MOUNTING
Build a custom keyboard with identical button
distances no matter how you stack them.
Designed to plug into any printed circuit board
horizontally mounted modules is not
recommended; the orientation of the rectangular,
lighted area will differ. See drawings.

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
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
