ABSTRACT:
An operating mechanism is provided for a circuit interrupter, such as a battery disconnect apparatus, including a housing and a number of stationary electrical contacts enclosed by the housing. The operating mechanism includes a cam member having a profile with first and second portions. A movable contact assembly includes at least one movable electrical contact, and is cooperable with the cam member to move the movable electrical contact into and out of electrical contact with the stationary electrical contacts. An actuating assembly pivots the cam member between a first position corresponding to the first portion of the profile maintaining the movable electrical contact in electrical contact with the stationary electrical contacts, and a second position corresponding to the second portion of the profile releasing the movable contact assembly in order that the movable electrical contact is movable out of electrical contact with the stationary electrical contacts.
