System and method for auxiliary contact assembly

摘要

A contact assembly for use in an electrical switching apparatus has an actuator. An enclosure comprises an interior space housing first and second stationary contacts fixedly mounted in spaced relation with one another in one of a normally closed position or a normally open position. A pusher is movably mounted in the enclosure and is selectively driven by the actuator to move between a normal position and an actuated position. The pusher comprises a top wall, a bottom wall and first and second side walls connected between the top wall and bottom wall to define an opening having respective first and second ends. First and second longitudinally spaced top ribs are on an inside of the top wall proximate the respective first and second side walls. First and second longitudinally spaced bottom ribs are in an inside of the bottom wall proximate the respective first and second side walls and laterally offset from the respective first and second top ribs. A movable contact is received in the opening. A contact spring is captured between the top rib and the bottom rib at either the first or the second end of the opening to bias the movable contact against the top rib and the bottom rib at the other of the first end and second end of the opening.
