  • Patent number: 6864768
    Abstract: An electrical switching system comprises a main housing enclosing an actuable apparatus including an actuator extending outwardly of the housing. A contact housing encloses an electrical contact and a pusher selectively actuable by the actuator to operate the contact. A mortise is provided on one of the main housing and contact housing and a tenon is provided on the other of the main housing and contact housing for joining the contact housing to the main housing. A snap lock resiliently locks the contact housing to the main housing.

  • Patent number: 6844800
    Abstract: 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.

  • Patent number: 6720510
    Abstract: The present invention is related to a pusher assembly (105) for use with an operator. According to one aspect of the present invention, a pusher assembly generally comprises a body portion (208); first window (216) formed in the body portion; second window (218) formed in the body portion adjacent to the first window, the second window being wider than the first window. According to another aspect of the present invention, a method for assembling a pusher assembly comprises the steps of inserting (602) a movable contact into a first position in a first window; moving (608) the movable contact to a second window; and rotating (610) the movable contact to a second position within the second window.

  • Patent number: 6677841
    Abstract: A contact assembly for use in an electrical apparatus comprises a housing and a pusher movably mounted in the housing. A movable contact is supported on the pusher. A stationary contact is proximate the moveable contact in the housing. A return spring biases the pusher to a normal position. A contact spring operatively associated with the moveable contact forces the movable contact against a stop associated with the pusher. The contact spring and the return spring are of identical construction and are positioned in the housing so that force or torque produced by the return spring is greater than force or torque produced by the contact spring.

  • Patent number: 6545237
    Abstract: A contact assembly for use in an electrical apparatus includes an armature comprising a base and a post having first and second ends. The first end is connected to the base and the second end comprises intersecting cross members defining four quadrants and a body extending between the cross members in one of the four quadrants. A moveable contact is received on the post. The moveable contact comprises an elongate bar having contact pads at opposite ends of one face and a central opening. The central opening comprises intersecting slots defining four quadrants and a void extending between the slots in one of the four quadrants. The central opening is slightly larger than the post second end so that the moveable contact is mounted to the post with the contact pads facing in a desired direction.
