Illuminated push-button switch assembly

Claim 1

An illuminated push-button switch assembly comprising: a hollow cylindrical housing, a base member closing said housing at one end thereof and having a first aperture and a pair of spaced apertures therethrough, electric switch means carried by said base member outside said housing and having switch contacts extending through said first aperture into said housing, an actuator disposed for reciprocating movement within said housing longitudinally thereof between a normal rest position and an actuating position, said actuator having a light-transmitting portion closing said housing at the other end thereof, said actuator having a cam surface disposed within said housing for engagement with and closure of said switch contacts in response to movement of said actuator from the rest position to the actuating position thereof, said actuator including a pair of resilient legs extending longitudinally of said housing and provided with cam means at the distal end thereof, said cam means being engageable with the outer edges of said a pair of spaced apart second apertures for cammed deflection to permit insertion thereof through said pair of spaced apart second apertures, said pair of resilient legs having retaining means adjacent to the distal end thereof, said pair of resilient legs resiliently returning to their original position after insertion through said pair of spaced apart second apertures for bringing said retaining means into position for engagement with the outer surface of said base member when said actuator is disposed in its normal rest position, lamp receptacle means formed integrally with said base member and projecting therefrom into said housing externally of said actuator, electric lamp means carried by said base member in said receptacle means, and bias means resiliently urging said actuator to the normal rest position thereof.
