ABSTRACT:
A unitized, switch activating mechanism for use in keyboard assemblies for activating snap dome or similar type switches. The mechanism includes a relatively hard actuating tip portion disposed intermediate an elastomeric conical skirt portion and a light guide portion. The conical skirt functions both as a light reflector and as a return spring. The light guide portion is constructed from a diffused translucent, relatively hard elastomeric material which functions as a highly efficient light guide for uniformly illuminating the key legend of the key board assembly with which the light guide interfaces.
