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.
