ABSTRACT:
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.
