mounting

Build a custom keyboard with identical button

distances no matter how you stack them.

Designed to plug into any printed circuit

board from

/16" to

/8" thick, modules stack

in any configuration, maintaining

/16" button

centers.

For Lightable Modules which will be continuously

lit, mixing ver tically mounted modules

with horizontally mounted modules is not

recommended; the orientation of the rectangular,

lighted area will differ. See drawings.

See Figure 1 Panel Cutout diagram for 6 button

module mounting dimensions. Refer to drawings

for other module dimensions.

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

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 continuously lit in temperature

controlled oven with continuously circulating air

for 24 hours.)
