Title:
Circuit protector having a slidable latch
Abstract:
A circuit protector comprising a case and a rocker or handle movable between "on" and "off" positions. A spring has one leg biased against the case and the other leg biased against the rocker for biasing the rocker to the "off" position. Within the case is a stationary contact and a movable contact carried by a movable contact blade. The rocker includes an extension which carries a pivotal latch lever and a slidable latch. The latch lever has a detent for restraining movement of the slidable latch. Further, the slidable latch includes a cam stop engaging a raised portion of the movable contact blade to keep the contacts engaged. A bimetal, on predetermined overload heating, engages the latch lever and pivots it away from the slidable latch, whereupon the detent is moved out of engagement with the slidable latch permitting the slidable latch to move upwardly under pressure of the movable contact blade and also permitting the rocker to be pivoted by the spring to the contacts "off" position.
