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 desoldering
the keyboard module then desoldering the

use an alternating current and reduced voltage.
The chart also lists maximum temperatures the
