Assemblies for providing the contacts of a circuit breaker with a pivoting motion. Each assembly is adapted to electrically couple the contact to the base of the assembly which is connectable to a terminal of the circuit breaker. Each assembly includes an arm for supporting an electrical contact, a pivot pin for pivotally mounting the arm, a base for supporting the pivot pin, and means for urging the pivot pin into contact with contact surfaces of the base. The arm is pivotable about the longitudinal axis of the pivot pin, and the arm and pivot pin are arranged such that at least two contact locations occur between the arm and the pivot pin.

Pivoting circuit breaker contact arm assembly

An improved connection assembly which saves space and eliminates the need for many conventional fastener means such as nuts and flanges. The assembly includes a receptacle for accepting and engagement member, wherein a small amount of clearance is present between the receptacle and the engagement member. The engagement member includes a slot having two substantially parallel surfaces. A threaded fastener is used to fix the engagement member within the receptacle by passing the fastener through an opening in the bottom of the receptacle and causing the threads of the fastener to cut into and engage the surfaces of the slot.

Fastening means

A plastic fastener assembly is provided which has a base with an upstanding stab which has a single first tooth formed on one side of the stab and at least one second tooth formed on the opposite side of the stab. A cover defines an opening for receiving the stab. The cover has a control rail adjacent the opening and a flap extending into the opening opposite the central rail. The rail slides along the surface of the first tooth during assembly and urges the first tooth and stab toward the flap until the rail engages the notch of the first tooth. The flap automatically moves from the base during assembly as the first tooth and stab move toward the flap. The flap engages the second tooth when assembled inhibiting separation of the stab and cover.

Fastener having dual teeth

A system for operating electrical equipment such as circuit breakers from a remote point is disclosed. A flexible push-pull type cable connects a linkage coupled to a pivoted handle and to a remote slider mechanism. The slider serves as a slave operator to effect reciprocation of a handle or similar operator element.
