Electric circuit actuating mechanism
First Claim
1. Mechanisms for actuating an electric circuit comprising, in combination:
- a housing;
a front wall having a broad surface;
means for movably mounting the front wall relative to the housing enabling any point of the broad surface to move in an actuation direction from a normal position to an actuation position, with the front wall being biased from the actuation position to the normal position; and
a multiplicity of de-energizing momentary switches mounted to the housing in a spaced arrangement, with the de-energizing momentary switches each including a slideable actuating pin biased in a direction opposite to the actuation direction from a first position to a second position, with movement of any point of the broad surface of the front wall in the actuation direction from the normal position sliding the actuating pin of at least one of the de-energizing momentary switches in the actuation direction, with the de-energizing momentary switches de-energizing the electric circuit when the actuating pin of at least one of the de-energizing momentary switches is slid in the actuation direction from the second position, with the energizing of the electric circuit not occurring as the result of the movement of the front wall.

Abstract
A mechanism (10) for actuating an electric circuit is shown including a switch box (11) fastened to a housing (26) to which a cover (60) is movably mounted. The threaded stems (54) of four de-energizing momentary switches (52) extend through and are held to the front wall (32) of the housing (26). The cover (60) includes a sleeve extending rearwardly of its broad surface front wall (62) and slideably received in a tubular extension (46) of the housing (26). A flange (72) on the sleeve abuts with ledges (50) formed in the tubular extension (46) to prevent movement therebeyond. The cover (60) can be pushed against the bias of coil springs (74) arranged concentrically around the stems (54) such that any point of the broad surface front wall (62) can be moved in an actuation direction to slide the actuating pins (58) slideable in the stems (54) of one or more of the de-energizing switches (52) to de-energize the electric circuit. The electric circuit is energized by actuating an energizing momentary switch (18) mounted to the switch box (11).
