Abstract
A key assembly including a key support structure, a switch, a base, and a moveable key. A light source, such as an LED, is mounted to the base to provide illumination for backlighting a translucent region disposed in the moveable key. In operation, when pressure is exerted against the moveable key, the moveable key axially translates to operate the switch. When the moveable key is in its at-rest position, light from the light source will be efficiently and uniformly dispersed through the key assembly to backlight the translucent region based on the location of said light source.
