Abstract: A lock having depending sides with holes therein is snap fit attached to a rocker actuator by causing the sides to straddle the actuator and the holes to receive beveled lateral tabs on the actuator, the holes being longer than the tabs to permit and define sliding movement of the lock on the actuator. Four feet depend from the depending sides of the lock within a housing opening in which the actuator is pivotally mounted to abuttingly align with corresponding abutments in the housing on opposite sides of the pivotal axis of the actuator, preventing rotational movement of the actuator when the lock is in a first position with respect thereto under the bias of a compression spring. The actuator is released by sliding the lock against the bias of the spring to move the feet radially offset from the abutments, thereby permitting rotational movement of the actuator in either direction, actuating corresponding switch contacts.

Abstract: A multiple leaf spring interlock switch having a pair of contacts in each side of an A.C. supply inherently biased to open positions and operated to closed positions by a linearly reciprocably movable cam acting only against the biased of the contacts. A latch is operable to alternately latch and release the cam on successive operations to hold the contacts closed or released. An interlock system has plural slides coupled to a rotary cam which is in turn coupled to a lock member to block movement of the linearly movable cam when either slide is in a non-operated position and to release the latch when a slide is moved to a non-operated position while the cam is latched, such action also causing the rotary cam to separate the contacts. An energy storage and release mechanism provides non-reversible momentum for a depressible operation.
