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

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

continuously lit in temperature controlled oven

with continuously circulating air for 24 hours.)
