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.
