Abstract
An illuminated membrane switch assembly lighted by internal bulb units. A membrane switch sub-assembly is finger touch actuated by a small translucent plastic button with a graphic overlay on its forward surface and a light-diffusing textured rear surface. A clear plastic backplate is provided for the membrane switch sub-assembly, and in one embodiment light is transmitted to the button directly through a complex partly opaque conductor area in the membrane switch by a single bulb unit mounted in the rear of an enclosing housing that has a white interior surface, and in another embodiment light is transmitted to the button through the switch conductive area by a bulb mounted inside the transparent backplate.
