LIGHTABLE MODULES

Light Source and Lamp Mounting

Each lightable button fits over a T-1 size LED

or incandescent lamp mounted to PC board

(see Figure 2-2a). The height of the lamp

should not exceed .250" (6,35 mm) from the

surface of the board. (Note: Grayhill does not

manufacture or sell LED's or incandescent

lamps).

For easy light replacement, mount the lamp or

LED through the back or solder side of the

board (see Figure 2). This method of mounting

allows you to replace light source without

removing the keyboard module. The other

method of light mounting (Figure 2a) requires

MOUNTING

Build a custom keyboard with identical button

distances no matter how you stack them.

Designed to plug into any printed circuit board

from 1/16" to 1/8" thick, modules stack in any

configuration, maintaining 11/16" button centers.

For Lightable Modules which will be continuously

lit, mixing vertically mounted modules with

recommended; the orientation of the rectangular,

for other module dimensions.

desoldering the keyboard module then

desoldering the lamp when it's necessary to

replace the light source.

The chart below lists ratings for a size T-1

incandescent lamp. To extend the life of the

lamp, use an alternating current and reduced

voltage. The chart also lists maximum

temperatures the module can withstand. For

higher temperatures, Grayhill offers modules

made of special plastics, polyester switch

housing and polycarbonate internal button. All

measurements were determined under

laboratory conditions. (Mounted model

Modular Keyboards

ORIENTATION OF MODULES

A module, depending on circuitry, may not be

symmetrical. Rotating it 180° will result in a

different pin location. Please note the button

PRINTED CIRCUIT BOARD LAYOUT

This layout provides the horizontal printed circuit board layout as viewed from the top side of the

PC board. Turning end to end will result in a different pin location. However, the dimensional

relationship will remain the same.

Lightable Modules–per drawing below.

This drawing indicates the layout to be used for a 6 button module with light sources mounted two

ways: the lamps for the upper 3 buttons are mounted from the top or component side of the board,

and the lamps for the lower 3 buttons are mounted by the easy replacement method. (See also Light

Source and Lamp Mounting.) Light sources, when mounted from the top side of the board, must

be mounted before the keyboard modules; when mounted, lamp should extend no more than .250"

(6,35 mm) above the board.

CIRCUIT DIAGRAMS

The bottom view of the line drawings shows

number (A1, A2, etc.) next to the pin locations

of each switch section. These pin numbers are

directly related to the circuit diagrams. For

example, if the switch under Button A of a

standard module were SPST, the pins would

be located at the "#2" Position. If the module

were a lightable one with SPST circuitry, the

pins would be located at the "#1" Position. If

other locations are desired, specify them.

The coded circuits shown are suggested

possibilities and each button may carry a

different circuit. Location of active pins on

each button may be varied to conform with

layout of the printed circuit board. Up to a 7-bit

code is possible under each button.

Combinations of simple circuitries are also

possible as shown in the sample diagrams.

SPECIAL LEGENDS

Molded-In Legends

For Unlighted Modules

In addition to standard white

legend on gray button, long-

wearing, molded-in legends are

available in white button with black

legend and white legend with red,

green or black buttons. Other

color combinations are possible.

Printed Legends (2 Styles)

Virtually anything which can be photographed

can be printed. Sturdy epoxy ink printing bonds

to the surface of the button. Standard printing

for the gray unlighted buttons is white; standard

printing for the translucent white buttons of the

lightable modules is black.

Top Surface Printing: Legend is applied directly

to top of button. Available on all standard,

unlighted modules.

Sub Surface Printing: Provides maximum wear

for printed surfaces. Available for lighted and

unlighted gray modules. Printed internal button

cap is protected by a clear outer cap.

Soldering Instructions

Series 82 Keyboard Modules have been

successfully tested for heat resistance to

soldering up to 260°C (500°F) for a maximum of

5 seconds. Careful flux cleaning is required

since the switch is not sealed. For applications

in excess of these limits or that require vapor

spray or immersion cleaning, contact Grayhill.

Printed Type styles

The type style chart below illustrates type style

and approximate sizes and limits for button cap

legends; other sizes are also available. Limitations

for legends differ with type size and character.

Legends for lightable modules are further limited

by the size of the internal button and lighted area.

Grayhill's library includes many popular legends.

Contact Grayhill for complete information.

Special Colors

Besides the standard

gray and black housings,

you may order white,

beige or brown. Button

colors may also be

specially ordered. For

ORDERING INFORMATION:

Special Legends

To order non-standard modules, information is

required for the areas listed below.

Your special order will be assigned a part number

for future identification. This number is

sequentially assigned and is non-descriptive.

1. Type of Module. Unlighted: 1-, 2-, 3-, or 6-

button. Lightable: 1-, 3-, or 6-button.

2. Mounting Orientation. Horizontal or

vertical.

3. Circuitry. Requirements for each button must

be listed by its reference letter designation.

For example: Button A = SPST, Button B =

4PST, Button C = 3PST, etc. For coded or

other available circuitry patterns a descriptive

diagram is required for each button.

4. Button Type (Legend). Grayhill offers four

legend types: molded-in; top surface printed;

sub-surface printed; and insertable. Unlighted

modules are available in all types. Lightable

modules are available in all types but molded-

in legends.

5. Button Color. Standard color for molded-in

legend modules is gray button with white

legend. Special button colors available are

white with black legends, red, green or black

buttons with white legends. Additional custom

colors are available by special order.

Lightable gray modules have a standard

translucent white button with black legend.

Special button color includes translucent red,

amber, yellow, blue and green. Lightable

black modules have a special opaque black

button; discuss special colors with Grayhill.

Colors can be intermixed, ie. buttons A-E

gray; and F, white.

6. Housing Color. Base in black. Upper

housing is black for lightable legends and

gray for all other module styles. Other stock

colors available include white, beige and

brown.

7. Legends. List legend requirement for each

button (Button A legend, "10", is type style

4GH088. Button B, "ON", is type style

1GH125, etc.). For legend information, see

page D-37.
