Company History
Staco Systems has designed and manufactured switches since its commencement
in 1958. During the early years, a small manufacturing and assembly team
accomplished the first series 30 switch used in a Fokker F-27 in 1960. Fifty years
later, Staco Systems has evolved into an internationally recognized, high-tech
endeavor with numerous experienced experts in manufacturing, engineering,
sales, and quality control. Our product line has expanded to include rugged
keyboards and keypads, electronic controllers, and panel assemblies for
hundreds of applications worldwide.

SERIES 90 DISPLAY PUSHBUTTON
LED or Incandescent Illumination
Incandescent display pushbuttons accept four T-1 midget flange based
lamps that may be easily serviced from the front mounting panel. The
display pushbutton is also available with a serviceable High Bright LED
light plate, which provide an extended service life. Low power consumption of the LEDs, as well as the heat sink capabilities of the switch/
indicator assembly, result in a pushbutton that is cool to the touch.

Five Legend Heights
There are ten display types offering a combination of legend characters or background illumination color. LED configurations are available
in seven types. Designer matched colors enhance display appearance and contribute to increased operator attention and efficiency.
Graphic designs and custom legend heights in these ten display types
are available. Display styles include full-screen displays, two-way, three-way and four-way split screen displays.
Each of these sections may have its own color and be lighted independently of the others.
Night Vision Goggle Compatibility
Display certification of Night Vision Imaging System (NVIS) compatibility per the requirements of MILSTD-3009. Unique lighting capabilities of the Series 90 provide display
legends that are fully qualified for both Type I Class A and Type II Class B
night vision goggles. Legends with incandescent lighting are available in
four colors, NVIS Green A, NVIS Green B, NVIS Yellow, and NVIS Red,
all qualified to MIL-STD-3009. LED based units provide NVG compatibility with NVIS Green B, NVIS Yellow and NVIS Red NVIS Blue and
NVIS White. Trimmed to low level for night operations, the legends are
sharp and clear with no glare or hot spots, and are not detrimental to
darkness adaptation for unaided eye visual monitoring outside the crew
station. For incandescent configurations and white LED-based pushbuttons, sunlight readable legends and NVG compatibility are combined in
the same pushbutton display.
6
Sunlight Readable Display
Illuminated sunlight readable legend is clearly legible in 10,000 footcandle ambient light. When not lighted, the
legend is not readable when viewed in the same ambient light.
Staco Systems's sunlight readable displays are clearly legible in direct sunlight eliminating the problem of loss of
legend legibility due to reflection of bright ambient light ... the equivalent of direct sunlight at 70,000 feet altitude.
When the display’s dead-front face is unlit, the legend is indiscernible. The display has a viewing angle of an
80°cone perpendicular to the viewing surface. All lighting measurements are made in Staco Systems'’s in-plant Mil
certified light laboratory. Certification is performed photometrically per the exacting requirements of MIL-S-22885.
Typical Pushbutton Display
Choice of seven factory installed Display Types or three customer
assembled and installed Display Types. (See Table 7). All are available
with choice of eight Display Styles (Table 5 ). A color filter, in a choice of
eight designer proven colors (Table 8), goes over each of the four lamps.

Replaceable Legend Plates
For those applications where the customer wishes
to provide or replace legend plates, an alternative
assembly is available in three display styles for use
only with the T-1 flange based lamp pushbutton.
These are similar to factory installed Type 2, Type 5
and Type 6 Displays.
Display Types 8, 9 and 0, consisting of a customer
supplied legend plate stacked between the factory
supplied face screen and diffuser plate, may be substituted for the standard bonded face plate assembly
in the T-1 lamp pushbuttons. Display Types 9 and
0 replaceable legends are available for LED pushbuttons. (See Table 7). The usable legend area is
.520” square. Overall size of the face screen is
.575” square with a viewing area of .495” square.
Customer installed legends may not be of equal quality as compared to the laminated factory installed
assemblies.

Incandescent Lamp Grounds
COMMON LAMP GROUND
Three types of incandescent lamp circuits are available. The schematics are shown in Figure 8 and the ordering codes in Table 4.
The “Common Lamp Ground” configuration is used when the power
for the display is from a single power bus. “Vertically Split” and
“Horizontally Split” Lamp Grounds allow the use of two power sources to illuminate the display of a given pushbutton. It should be noted
that the specific lamp circuit option which is utilized is totally independent of the display style (i.e., full screen, 2-way, 3-way or 4-way
splits) of Table 5.

white, lunar white, blue and aviation green) plus lemon yellow.
Night Vision Imaging System colors are plotted in the U’-V’ coordinates of 1976 CIE chart of figure 14. All four of
the colors defined in MIL-STD-3009 are available in incandescent displays. LED applications may use green B,
yellow and red. When ordering, colors are selected from Table 8.

Mounting Procedure
1. Remove pushbutton from switch/indicator assembly by pulling straight out. Use tool # 15190 for easier removal.
2. Rotate locking screws inside front of switch/indicator assembly counter clockwise with a small screwdriver.
This will release mounting cams.
3. Slide mounting sleeve and panel spacer off of the switch/indicator assembly.
4. Install switch/indicator assembly through panel cut-out from front of panel. Assembly is marked with word “TOP” to help properly orient position of the assembly in the panel.
5. Replace panel spacer and mounting sleeve.
6. Rotate locking screws clockwise to bring mounting cams to lock position. Recommended mounting torque is 10±2
oz. in. (0.071+ 0.014Nm).
7. Be certain that pushbutton has lamps or dummy lamps installed in all four positions before inserting into mating
switch/indicator assembly.
8. To Insert the pushbutton properly, be sure that the index post is at the top and that the pushbutton is held square
to the switch housing.
9. The two panel spacers, together with the mounting sleeve, provide various options for fitting the switch/ indicator
assembly to mounting panels with thicknesses ranging from essentially zero to a maximum of about .75” (see
dimensional drawings for exact thickness for each configuration).
10.For extended mounting of the assembly, as in conjunction with edge-lit panels, the black panel spacer is left
installed on the assembly before it is inserted in the panel cut-out so as to be in front of the panel when
installation is complete.
11. On sealed switch/indicator assemblies mounted flush, the panel seal is installed under the housing flange and on
the front of the panel. On the extended mount sealed units, the panel seal is place between the panel spacer
and the front the panel. (Refer to dimensional drawings.)

MODEL 99 SWITCH / INDICATOR
Crimp Pin Termination
Reduced wiring time with increased reliability - Staco Systems's Model
98 Switch/Indicator and the Model 99 Switch/Indicator and Display
Pushbutton, offer individually mounted units with crimp pin termination
receptacles. These units provide the advantage of fast and easy wiring
as well as quick and simple post installation maintenance. The crimp
pin terminals and the termination receptacle, may be removed from
switch/indicator. All soldering is eliminated, greatly reducing installation
time. Termination receptacles may also be prewired for connection after
switch/indicator assemblies have been installed. The crimp pin terminals
and associated installation tools are all military standard parts to assure
wide availability and high reliability.
Connecting wires, with socket contact crimp pins, are shown inserted in the switch/indicator termination receptacle. Wires can be removed and replaced individually, or the termination receptacle, with all wires left in place,
can be removed and replaced as a single unit.
Switch/Indicator Options
Model 98 and 99 assemblies with crimp pin termination receptacles are available with SPDT or DPDT circuitry,
momentary or alternate switch action, silver or gold contacts, EMI/RFI shielding, with or without moisture sealing
and with the optional Immersion Seal/High Impact Seal/Solvent Resistant Seal. Matching Indicators are also
available.
Display Pushbutton Options
Model 92 lighted display pushbutton is used with both the Model 93 and Model 99 Switch/Indicator with
Pushbutton assembly. The same illumination and display options are available for both the Model 93 and Model
99 Assemblies.
Assembly
Model 99 assembly is comprised of a termination receptacle, a switch/indicator body, and a display pushbutton.
The termination receptacle and/or individual wires and the pushbutton can be removed for servicing and
replaced without disturbing the switch/indicator installed in a control panel.

WATERTIGHT SEAL
The Watertight Seal is part of the Staco Systems Series 90 family of illuminated pushbutton switches and indicators. It is covered
by MIL-S-22885/112. Assemblies incorporating this seal can be
ordered as an option to the Series 90.
This Watertight Seal is a flexible elastomeric boot which is an integral part of the pushbutton and provides a seal at the front panel.
The flexible nature of the seal allows actuation of the switch under
three feet of water while still sealing against leakage through the
switch or panel opening.
This same seal performs as a Splashproof Seal to protect against
washdowns using directed streams of water.
The seal is intended to protect the switch/indicator, as well as the behind-the-panel areas, against elements such
as rain, fog, snow, salt spray, sand and dust.
The watertight seal also insures that the pushbutton remains attached to the switch under high impact shock conditions (approximately 1,500 Gs). The combination of pushbutton with watertight seal will remain attached to the
switch when tested per MIL-S-901 for Class I and Class II equipment.
Panel Spacing of switches or indicators with watertight seals installed is 1.06 inches (26.9 mm) minimum center
to center horizontally or vertically. If the Pushbutton Guard (Assembly 15204/005) is to be installed, the minimum
horizontal center to center spacing is 1.40 inches (35.6 mm).

MATRIX HOUSING ASSEMBLIES
Series 90 Matrix Housing Assemblies
Matrix Housings are available in two different mounting configurations and any
matrix arrangement to meet the customer’s
required number of stations. Constructed of
square aluminum alloy tubes, the lightweight,
yet rugged assembly actually strengthens
the panel, regardless of cutout size. Matrix
Housings are constructed to meet the
requirements of MIL-S-24317. Installation
time is greatly reduced, requiring only one
panel cutout instead of many. For non-EMI/
RFI applications, a black anodized finish per
MIL-A-8625 is applied to the housing. For
EMI/RFI shielded applications, a chemical
film finish, per MIL-C-5541, is applied. Series
90 Switches and Indicators are inserted in
the front of the matrix and locked in place by
rotating the screw actuated locking cams.
Termination Options
Solder, PCB, and crimp pin terminations are available. Model 94 and 96 Matrix Housings for solder and printed
circuit terminations provide for direct connection of wires to the switch/indicator terminals. Model 95 and 97
Matrix Housings, for crimp pin connections, are lengthened to accommodate a crimp pin receptacle. The
mounted receptacle mates with a standard crimp pin switch/indicator, enabling the crimp pin socket contact to
make electrical connection to the switch/indicator terminals. The crimp pin matrix assembly allows the switch
to be removed from the front of the housing, leaving the receptacle and wiring in place. The receptacle can
also be removed from the rear of the housing, leaving the switch in place, or the wire may be removed from the
receptacle without disturbing the receptacle or switch/indicator assembly.
Rear Flange Mount Matrix Housings
Model 94 and 95 Matrix Housings for rear mounting of the assembly to the customer’s control panel are available with flanges having slotted mounting holes. Flanges may be located horizontally on the top and bottom
of the housing, vertically on the two sides, or on all four sides for applications where extreme vibration may
be encountered or for EMI/RFI shielding to assure complete panel contact for grounding. All units conform to
shock requirements of MIL-STD-202, Method 213, condition B.
Flange set-back is custom made to accommodate customer’s desired panel thickness. Flange set-back, dimension “H”
shown on housing drawings, measured from the pushbutton top to front of the mounting flange is variable, depending on
panel thickness and desired pushbutton extension, and must be specified by customer in the part number rationale. See
ordering information. The matrix housing is shipped fully assembled, ready to be installed in the customer’s control panel.
21
MATRIX HOUSING ASSEMBLIES
Front Dress Bezel Mount Matrix Housings
Models 96 and 97 Matrix Housings are supplied with attractive extruded aluminum dress bezel. The entire

are installed in the field. For proper operation, either this “discard”
plate, four T-1 lamps, or a combination of lamps and “dummy
plugs” (devices which simulate the specified lamps) must be used to prevent damage to the unit.
Factory-supplied lamps have nominal brightness as specified by the manufacturer in Table 6A. These have a mean spherical
candle power (MSCP) tolerance of ± 25%. Unless otherwise specified, all brightness tests performed at the factory, and those
published in this document utilize calibrated lamps with a luminous intensity of .15 ± .01 MSCP.
Light Emitting Diodes (LEDs)
The voltage options are 5 or 28 volts. LED polarity and other options are as specified in Table 6B. These LEDs
are a serviceable part of the pushbutton.
Incandescent Lighting Circuits
Electrical connections for pushbuttons lighted with incandescent lamps are shown in Figure 8. The lamp circuit is
optionally available with:
a)Common lamp ground for all four lamps (full ground plate); b) Vertically split ground plate (the two lamps on the left half and the two lamps on the right half may be on separate power circuits with separate grounding);
c) Horizontally split ground plate (lighting for the top half and the bottom half may be on separate power circuits).
The choice of lamp circuit grounding scheme is completely independent of the selection of legend display style (full screen
display, two-way horizontal split, etc., as shown in Table 5). The split grounds allow the lamps of a display to be powered from
two separate power sources.
Each incandescent lamp is lighted independently from the other three by applying power to the pin designated in the schematic. The power may be dc or low-voltage ac, within the rating of the lamp. Standard lamp selections are listed in Table 6A.
Incandescent-based displays are available in the colors indicated in the chromaticity diagram of Figure 13.
LED Lighting Circuits
Light emitting diode (LED) arrays within the Series 90 pushbuttons are available as an alternative to incandescent lamps.
Each of the four quadrants of a display is lighted using an assembly of three LED chips, giving a total of 12 LED junctions per
pushbutton. Schematics for typical LED configurations are shown in Figures 9 and 10. The required current regulating resistors are included in the pushbutton. There is also a voltage dimming option.
Unlike the incandescent pushbutton versions without common bussed switch bases, some LED configurations power need
only to be applied to one pin to control the lighting of a half-screen LED display if the display style is full-screen or half-screen
displays.
35
MODEL
99 SWITCH/INDICATOR
PRODUCT
DESIGN
& ENGINEERING DATA
For common lamp circuit configurations common terminals (pins 6 and 9) may be used as the common return circuit for redundancy.
The schematics of Figures 9 and 10 are typical. Figures 56 and 57 provide a complete set of schematics for all standard colored
LED configurations.
Current Requirements for LED Lighting: For 5 volt dc systems, all configurations use 45 mA per quadrant when illuminated.
Thus, a full-screen unit would use 180 mA, a two-way split with one half lighted would use 90 mA, etc.
For 28 volt systems, the current requirements dependent upon the configuration. When operated at 28 volts dc, either for a
full-screen or two-way configuration, the forward current is 20 mA for each half screen which is illuminated (40 mA with both illuminated). For three-way split, the one-half screen is 20 mA and each quarter screen is 20 mA (for a total of 60 mA with all three
areas illuminated). On four-way split configurations, each quadrant uses 20 mA ( mA with all four areas illuminated).
Maximum current usage for each configuration is tabulated in Table 6B. The current requirements listed are worst-case with all
legend areas lighted at maximum brightness.
LED Lighting Control
The accompanying schematics identify the pins to control the lighting of the specific portions of the displays on
LED-based pushbuttons.
Current Sourcing/Sinking for LEDs
Figures 11 and 12 show simplified schematics of typical control circuits for driving the LED circuits. LED lighted pushbuttons
may be configured through Table 4 for either current sourcing (codes 7 and 9) or current sinking (codes 8 and 10).
One characteristic of current sourcing is that it can be used to isolate the lamp load from direct power connection
if desired. For this, the cathode side of the LEDs is always grounded through a current-regulating resistor. The
driving circuits supply voltage to the anode side of the LEDs to illuminate them.
Current sinking, on the other hand, enables the controlling circuits to switch the cathodes to ground to light the
LEDs. The is a simpler control circuit to implement if MOSFET logic is being used. Also multi-channel output driver ICs with common grounded emitters are readily available.
Dimming
While incandescent lighting may be controlled by varying the amplitude of the applied ac or dc voltage, this is
not the ideal way to control LED lighting. LEDs are current-driven devices and operate best at the rated current.
Dimming is best accommodated
by turning the LEDs on and off at
a rate of several thousand times
per second. During the period of
time that they are on, they are
driven at their rated current. The
ratio of on-time to off-time then
controls the brightness. The Staco
Systems DDM111 and DDM111A
Digital Dimming Module are an
ideal way to precisely control
LED brightness. The DDM111
and DDM111A may also be voltage dimmed provided the option
is selected from the catalog
(only available in 28 volts) The
DDM111 and DDM111A are briefly
described on page 56.

Legends
Type Style and Fonts
The standard type face used for legend text is Alternate Gothic Number 2 (AG2), a condensed gothic, sans serif style.
The nominal letter height-to-width ratio is approximately 6:1. Always Visible White (AVW) legends are an exception;
they use the Helvetica Light font.
Character Heights
The character height, as defined in this document, is the distance (in decimal inches) from the top to bottom of a
capital letter (no descenders) in the standard font AG2. Unless otherwise specified, the size of punctuation and
symbols in that font will be artistically proportional to the size specified for the capital letters.
As listed in Table 5, the standard character heights for the Series 90 Product Line are .072, .087, .100, .125 and
.145. Other AG2 character heights, available by special order (or if needed, for special artwork) are: .060, .066, .075, .077,
.080, .082, .090, .094, .097, .105, .110, .114, .120, .132, .139, .155, .164, .175, .188, .203, .219, .239, .263, .293 and .329.
Standard Character/Symbol Set
The standard AG2 typeface provides capital letters and numerics in all the sizes listed above. Lower case characters are not available in this font. Many typical European characters such as Ä, Å, É, Ö, Ñ, Ü, and others, are
available as standard within this font. Other symbols available in AG2 include arrows, @, #, $, %, &, (, ), ', !, ., +, /,
:, ;, =, ?, \, _, <, >, *, ±, °, 1/2, 1/4, and others.
The “character height” of an arrow is the length from the tip of the point to the end of the shaft, independently of its
orientation, i.e., a .145” arrow will have the same appearance if vertical or horizontal.
The symbols * and # are available either as proportional to the size of the AG2 font or as full-size characters with
the same height of the capital letters. Unless otherwise specified, the symbol used will be the proportional one.
Optional Fonts
By special order Helvetica Light and Helvetica Medium are available in a range of sizes similar to that of AG2. Either
of these Helvetica typefaces may also be ordered in their normal, condensed, bold, or expanded variations. Both of
these typefaces provide capital letters, numbers, lower case characters, and many of the symbols and European
characters identified in the previous paragraphs. The “characters per legend area” of Table 5 does not apply.
Math and Greek Symbols Sets
Math symbols and Greek characters available by special order and may be mixed with the standard AG2 font.
Other Non-Roman Alphabets
Camera ready art, at 10 times the final size, is required for legends using other non-Roman characters
such as Hebrew, Japanese, Korean, Chinese, Russian, Arabic, Sanskrit, etc. A bold face character set,
with a stroke width ration of 6:1 or 8:1 is recommended.
Special Artwork
Simple shapes, such as squares, rectangles, borders, circles or diagonal lines may be generated in the normal legend-making process. For complex shapes, icons, or others graphic symbols, it is recommended that the customer
supply camera-ready artwork at a 10:1 scale (to fit in a 4.95” square area) for photographic reproduction.
Characters Per Legend Display Area
The approximate number of AG2 characters of a given size which will fit into a display area is given in Table
5. AG2 characters are proportionately spaced (i.e., a character “M” or “W” is about three times as wide as
the character “I”). The actual number of characters will depend on the specific characters used. If the specific characters used in a given area exceed the space available, but by no more than 10%, the characters
will be condensed by 10%, using the same height but less width, on order to accommodate the legend as
requested by the customer.

Display Types
The display types available as standard products in the Series 90 are listed in Table 7, along with the corresponding symbol used in MIL-PRF-22885.
Legend and Faceplate Assemblies
The lens and faceplate assemblies are part of the pushbutton assembly. These pushbuttons are removable
from the front of the panel to allow the replacement of incandescent lamps without the need for special tools.
LEDs are not replaceable.
Color Filters
Incandescent and LED display types 2, 3, 4, 5, 8 and 9 utilize color filter caps which may be interchanged
among the four color cell areas or replaced with color caps ordered from the factory. Incandescent display
types 1, 6, 7 and 0 utilize flat color filters which are an integral part of the faceplate assembly and are not
replaceable in the field.
Customer Replaceable Legends
Display types 8, 9 and 0 allow for the customer to replace the legends. Each type is available in configurations
with incandescent lamps. For LED-lighted pushbuttons display types 9 and 0 are available. The overall size of
the replaceable faceplate is .575” (14.6 mm) square, with a viewing area of .495” (12.6 mm) square. Displays
with customer installed legends may not be of equal quality to that of factory installed assemblies that are laminated together.
Sunlight Readability
Sunlight readable displays in the Series 90 Product Line provide a black, non-reflective, dead-front appearance
when no lighted and provide brightly lighted legend characters, in the specified colors, when the displays are energized. This display (type 6) protects the crew station viewer from false indications in direct sunlight at high altitude.
The design overcomes two problems associated with high-intensity light directed at the instrument panel. First,
when lighted, it enables the viewer to read the legend despite the intense brightness of direct sunlight at 70,000
feet altitude. Secondly, the design prevents this high intensity light from causing the legends to falsely appear to be
lighted when the are actually unlighted. The measure of its effectiveness is by means of calculating two sets of contrast ratios based on laboratory measurements conducted under very specific conditions.
Contrast Ratios
The average contrast ratio of each legend character to the background is measured with an incidental illumination of 10,000 foot-candles minimum, at 5,000° ±500° Kelvin color temperature, directed at an angle of 45°
±2° to the normal of the viewing surface. Luminance readings are point readings taken with a calibrated photoelectric photometer directed perpendicular to the display surface. At least three readings are taken at equally
spaced points on each legend character and the readings averaged. At least three readings are then taken at
points in the background immediately adjacent to each character. The contrast ratios C , and C , are calcuL
UL
lated for each character.
The lighted contrast (ON/BACKGROUND) is defined by C = (B - B )/B

Lamps for testing are aged and selected for a mean spherical candlepower (mscp) of .15 ± .02, for general testing,
and .15 ± .01 for QPL testing. The standard legend for SLR testing has a character height of 0.1 inch (2.54 mm),
two display lines, and the words “REMOTE” on the top half and “ALT LOW” on the bottom half.
Incandescent Type 6
The average contrast ratio of each lighted legend character to background is 0.6 minimum, except for blue
which will be 0.2 minimum. In the unlighted legend condition, the average contrast ratio of each legend character to the background will have an absolute value less than or equal to 0.1.
SLR And NVIS-Compatibility
Incandescent LED pushbuttons with NVIS-compatible colors will have an average contrast ratio of each lighted
legend character to the background of at least 0.6 in accordance with MIL-STD-3009. The unlighted contrast
ratio for each individual character will not exceed 0.1. Incandescent lighted NVIS Red will have an average
lighted contrast ratio for the entire legend of 0.6 or greater, however, individual characters may be below that
contrast ratio. LED pushbuttons add NVIS White and NVIS Blue to the available colors.
Sunlight readability requirements apply to NVIS-compatible LED pushbutton configurations.
SLR Sealed Displays
SLR performance is not degraded for standard Dripproof, Splashproof or Watertight seals. SLR requirements do
not apply to Solvent Resistant or Hazardous Environment Seals.
Night Vision Imaging System
Series 90 Products, when type 7 legends are specified, provide instrumentation displays which are compatible with
night vision imaging systems (NVIS). NVIS compatibility is ensured with extensive testing and analysis by a computer controlled and calibrated spectral radiometer, the most accurate and sophisticated NVIS laboratory equipment available. This system is used to qualify products, to evaluate incoming filters and to perform certifications.
Also, all NVIS-compatible products are 100% inspected for IR leakage prior to shipment.
NVIS Qualifications
The Series 90 incandescent versions are fully qualified to MIL-STD-3009 under MIL-S-22885/101 for NVIS compatibility for the colors Green A, Green B, Yellow and Red, and for Type I systems, Class A and Class B goggles,
and for Type II systems, Class A and Class B goggles, where applicable. These NVIS units are also “sunlight readable” per MIL-S-22885/101.

Night Vision Imaging System Types
MIL-STD-3009 defines night vision imaging systems by type and class. Type I is direct view imaging where the
Gen III night vision goggle (NVG) is used to view outside the cockpit and the pilot glances under the goggles to
view the instruments. Type II also is a Gen III goggle, but uses a projected image where the pilot simultaneously
views both external and internal information through optical mixers.
Night Vision Imaging System Classes
Two NVIS classes have been defined, based on the cut-off frequency of the filters used in the goggles. Class A NVIS
uses the 625 nanometer (nm) minus blue objective lens filter while Class B uses the 665 nm filter. The lower cut-off
of the Class A filters allows for maximum near-IR response to tree bark, grass and other green vegetation, a general
requirement for helicopter applications operating below tree-top level. The Class B filter, with the higher cut-off, allows
the goggles to be used in conjunction with orange and red warning indicators in the cockpit, and is intended for aircraft which are operating above tree level.
NVIS Radiance
The NVIS radiance (NR) is measured for Class A (NRA) for compatibility with 625 nm applications, and for Class
B (NRB) for 665 nm systems. Both are the result of spectral radiance measurements, in 5 nm increments, from
450 to 930 nm. The readings are automatically scaled by the spectroradiometer system to a selected brightness level
given in footlamberts.
NVIS Radiance Requirements
The accompanying table summarizes the NVIS
radiance specification (MIL-STD-3009, Table IX) for
configurations which are applicable to the Series 90

NOTES:
1 This is an approximate
1
value. Actual number of
characters will depend on
the specific characters
used. If the specific
characters used exceed
the space available, the
characters will be con densed, but only by 10%
using the same height,
in order to accommodate
the legend requested.
2 The character format for
legend alphanumeric is
Alternate Gothic No. 2
(AG2), a condensed,
sans serif font.
3 The character height, as
defined here, is the dis tance (in decimal inches)
from the top to bottom of
a capital letter (excluding
descenders) in the stand ard AG2 font. Unless
otherwise specified, the
punctuation and symbols
in that font will be artist ically proportional to the
size specified for the
capital letters.
4 The standard type font,
AG2, provides capitals
and numerics; lowercase
characters are not avail able in this font. Many
foreign characters, such
as Å, É, O, Ñ, U and
others are available.
Helvetica typefaces,
math symbols and Greek
characters are available
by special order.
5 Camera ready art, at 10
times the final size, is
required for non-Roman
characters (such as
Hebrew, Japanese,
Korean, Chinese and
Russian).
6 For special graphic art work, contact the
factory-based Sales
department.

15091 Dummy Lamp Plug
NOTES:
1 All lamps are T-1 sub-midget flange based.
Lamp code numbers 01 through 09 and 11 through
19 require four (4) each per pushbutton.
2
Current (milliamp) values are with all four quadrants
lighted.
3
Lamp specifications and performance are published
by the lamp manufacturers. Staco Systems does not
warrant lamp performance as specified.
4
When lamps are not furnished with pushbuttons, a
removable fiberboard plate is installed at the factory
in order to insure the pushbutton returns to full
normal position. This plate is removed and discarded
when lamps are installed. Applies to code 00 and 10.
5
Caution: Do not install pushbutton without lamps or
dummy lamps in all four positions, or a fiberboard
(discard) in place. Otherwise, when power is
connected, a short circuit will result.
6
Pushbutton with Night Vision Imaging System (NVIS)
compatible display (Type 7, NVG) must be “sealed.”
7
8
Recommended for lower faceplate temperature.
9
SLR performance may be degraded with these lamps.
10
Unless otherwise specified, MSCP values are ± 25%.
6
APPLICATION NOTES:
The faceplate temperature will stabilize at ambient
room temperature of 72°F, and with no forced air
movement, 120°F with .72W to 1.14W of power input,
depending on display type, and at 140°F with .87W to
1.62W. It is recommended to reduce the input power
and improve the heat exchange efficacy of the pushbutton either by:
1.Reducing the input power to the lamp.
2.Utilizing forced air movement.
3.Reducing duty cycle, thus reducing over all input
power per unit of time of each lamp.
4.Reducing the number of active lamps for long
periods of operation.
5.Mitigating excessive power radiation and conduc tion with reductions in ambient temperature,
increased flow of cooling air, and enhanced
heat-sinking of mounting panels.
6.Using low wattage lamps, such as the 3071 for
5 volt applications or the 3335 for 28 volt
applications.
7.Changing design to higher efficacy illuminant
source, Light Emitting Diodes (LED) lighting.

HEADS
Models 91, 92 & 98
The tables not only identify the code numbers associated with each option, but also supply additional information
relating to the option. The convention for notes is that a number followed by a period (i.e., 1.) is a general note and
the text which follows applies to the entire table. Whereas a specific note refers only to the item with the corresponding symbol (i.e., 2 ) in a manner similar to a “delta note” on a drawing.
The term “sealed” for switches and pushbuttons in the following tables are for “dripproof” seals (to withstand a spray of five
gallons in five minutes). For “splashproof”, “immersion” and “solvent-resistant” seals, see the section beginning on page 20.)
To have a dripproof unit, both the switch and the pushbutton should be ordered as “sealed”. All Type 7 display
pushbuttons, NVIS compatible, are configured as sealed units.

HEADS
Model 98 Switch /Indicator Without Pushbutton
Models 93 & 99
Each of the standard and optional features of the Series 90 Switch and Indicator are described in this catalog. The
part numbering rationale provides for ordering a complete switch or indicator assembly with a pushbutton assembly,
including illumination source, legend, colors, and display style. Individual switch or Indicator assemblies and individual pushbuttons may also be ordered separately.
To determine the type of switch or indicator and push-button you need, simply insert the code numbers from Tables 1
through 8, as outlined in the following pages, in the appropriate locations in the part number listed with the charts.
Model 98 Switch/Indicator is supplied with a crimp pin termination receptacle installed. To designate the type of
switch or indicator required simply insert the appropriate code numbers from Tables 1, 2, and 3 on pages 12 and 13.
The Model 99 includes a Switch/Indicator and a Display Pushbutton. To designate a complete Model 99 assembly,
insert the code numbers from Tables 1-8. The associated crimp pins are not furnished with each part, but may be
ordered separately as part number 15095.
The Model 93 configurator, shown below, provides the part number information to define switch and pushbutton
assemblies. It is a 16-digit part number, with no spaces or hyphens, followed by the text for the display.
Example: Following the code number 93, the next four sets of digits, from Tables 1 through 4, define the switch portion of the assembly. The rest of the part number, from Tables 5 through 8, defines the display pushbutton. The color
for each of the four quadrants must be included, even if they are all the same color in a full-screen display.
The convention for legend text is to enclose the text for each area within parenthesis and to indicate a new line by
inserting a semi-colon. In the example below, the Display Style (of Table 5) is a 42. This represents a three-way split
with character height of .087 ".
The top half has two lines, OIL and OK. The lower left quadrant has the text LO; the lower right quadrant has the
text HOT. The quantity of parenthesis pairs corresponds to the area numbers identified in Table 5. The text for each
area is enclosed by parenthesis. If one area is blank, a space would be inserted between the parenthesis, for example: (OIL;OK)(LO)( ).

Text for legends, when applicable, follows the /005. An example using the Model 99 would be as follows:
9917418156257777/005 (Bright; LEDs)
Switches, indicators and pushbuttons cannot be reworked in the field to retrofit existing equipment with the Watertight
Seal. All applications requiring the use of the watertight seal must use factory supplied and assembled hardware.
A switch/indicator service kit is offered which contains ten sets of panel seals and retainers. This kit, P/N:
15196/005, can be used to replace damaged or misplaced hardware.
Matrix assemblies utilizing Series 90 switches cannot make use of this watertight seal. Customer replaceable
legends (Pushbutton Types 8 and 9) are not available with watertight seals.

number, called a Location Code.
The first digit in the Location code identifies the horizontal row and the second digit identifies the vertical
column. In the example 2-3 is the second row down
and the third
column to the right. Location 1-1 will always be top
left as viewed by the operator. Pre-numbered work
sheets are available from the factory upon request.
