The handle of a circuit breaker is controlled manually by sliding a linkage member right, or left, upon a flat surface of the housing of the circuit breaker. The linkage member is at one end pivotally attached through a knurled pin to the handle and, at the other end, a handhold portion is provided with a recess admitting a finger, or thumb, to push or pull the linkage member and actuate the circuit breaker through its handle.
