Abstract
A miniature illuminated push button switch includes a push button capsule mounted in a housing containing a switch assembly. The capsule contains a plurality of lamps for illuminating the face of the push button. The push button can be depressed into the housing for actuating the switch assembly, which includes a pair of sub-miniature switches mounted below a corresponding pair of spring biased plungers projecting from the capsule. The lamp contacts make contact with corresponding conductive volute spring contacts inside the housing. The spring biased plungers are pushed into contact with the switch contacts when the push button is depressed. The capsule can be removed from the housing, say for relamping, by pulling the capsule out of the housing to detach the capsule from the latch. An alternate action cam assembly latches the push button in a depressed position for holding the switch contacts closed on alternate actuations of the push button.
