A cutting device in accordance with some example embodiments is provided for use with an arbor assembly. The cutting device includes a blade having a plurality of teeth, and a back plate at a proximal end of the blade. The back plate has an outer end surface in which a plurality of ramp surfaces and pin locking recess are provided. A central through hole extending through the back plate. The ramp surfaces only allow the cutting device to be rotated relative to the arbor assembly in one direction.

A driver is used to manually drive a fastening member. The driver includes a shank, a handle provided at an end thereof, and a socket provided at the opposite end thereof. The socket has a receptacle which includes a front portion extending from a front face of the socket a predetermined distance and a tapered portion extending from the front portion a predetermined distance. The front portion is larger than the outer dimension of the fastening member and is formed from walls which are parallel to the centerline of the socket. The tapered portion tapers inwardly from the front portion toward the centerline. The tapered portion extends uninterrupted 360&#xb0; around the receptacle such that a rear edge of the fastening member continuously contacts the tapered portion when inserted therein.

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.

System and method for auxiliary contact assembly

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.
