  • Current switching member for circuit breakers
    Patent number: 4339642
    Abstract: The movable arm of a circuit breaker provides at its lower extremity a backing surface against which a copper carrier is clipped. A movable contact is affixed to the exposed surface of the carrier beyond the backing surface, such that current flow between the contact and a flexible, conductive braid, also affixed to the carrier, is conducted through the carrier rather than the arm which may then be fashioned from a less expensive, relatively low conductivity material such as steel.
