STABILIZER FOR A CIRCUIT BREAKER HANDLE MECHANISM

摘要

A switching mechanism interfaces a flexible shaft to the handle of a circuit interrupter which handle is rotated in a arcuate path betwee n an on position and an off position. The switching mechanism includes a handle attachment for rotating between the on position and off position. The switching mechanism includes a base plate which is attached to the circuit interrupter and secures a flexible shaft thereto. The other end of the flexible shaft is connected to a remote, exteriorly mounted operating handle. The base plate has a perpendicularly extended tab with ears thereon which feeds through an opening in a portion of the linearly moving part of the handle mechanism actuator. Since the present apparatus is to be disposed on the side of the circuit breaker, there is a likelihood for sideways twisting or tors ional rotation of the yoke in the direction perpendicular to the plane in which the ar c of the handle of the circuit breaker is to move during opening and closing operations. The presence of the tab which captures the actuating mechanism between the ears thereof and the flat surface of the base prevents or greatly minimizes sideways twisting, torsion or rotation during the operation of the handle mechanism.
