A circuit breaker includes a housing, separable contacts, an operating mechanism having a pivotally mounted operator handle for opening and closing the separable contacts, and a trip mechanism releasing the operating mechanism to move the operator handle to its tripped position. A micro-switch includes an actuator lever movable between an actuated position and a non-actuated position and adapted to engage a surface of the operator handle. The micro-switch also includes a normally open contact having a closed state corresponding to the actuated position and an open state corresponding to the non-actuated position. The operator handle surface engages and moves the actuator lever to the actuated position in only the ON position of the operator handle. The actuator lever is in the non-actuated position in the OFF position and the tripped position of the operator handle.
