(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 figure 1 panel mount cutout diagram lightable modules unlighted modules 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. 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.
