ABSTRACT:
An operating mechanism for the operation of a circuit breaker by movement of a toggle handle in a vertical plane and a switch handle movable in a horizontal plane, and comprising a housing, a shaft, a toggle handle and a gear plate mounted on the shaft, and a pivot plate. The pivot plate has slots arranged in an arcuate path, a butterfly cut-out section which receives and engages the switch handle of the circuit breaker, and an arcuate opening and pin arrangement for guiding the pivot plate in its pivotal movement. The gear plate has a flat portion and an arcuate portion with gear teeth. These gear teeth on the gear plate enter the slots in the pivot plate to rotate the pivot plate for operation of the switch handle. Rotation of the pivot plate is generated by movement of the toggle handle in a vertical plane.
