ABSTRACT OF THE DISCLOSURE A single push-button switch comprising a housing, a switch activating rod extending within the housing, and an electrically conductive element displaceable by the rod within the housing. The rod is resiliently biased axially in one direction to a first position where the conductive element will engage a first set of electrical contacts in the housing. Lock means is provided in the housing and associated with the rod for locking the rod in a further position when displaced axially in opposition to the first position. The conductive element en- gages a second set of electrical contacts when the rod is locked in the further position. The rod is unlocked and urged to the first position by depressing the lock means. This lock means is a flat elongated flange member having a through bore therein to permit passage of the rod therethrough. The flange member has a spring biased end inwardly of the housing and an actuating end extending outwardly of the housing. The spring biased end urges a portion of the flange member adjacent the through bore against the rod whereby the portion of the flange member will enter a cavity provided in at least a portion of the rod when in planar alignment therewith to maintain the rod in the further position. The flat elongated flange member has finger engage- ment means at an actuating end thereof and extending to a side of a finger engaging end of the rod to permit unlocking of the rod by depressing the actuating end.
