An indicator on a stored energy motor operator indicates that the circuit breaker is "on" when the contacts are closed and the handle is in an on position and when the contacts are open and the handle is in an on position. The indicator only indicates that the circuit breaker is "off" when the contacts are open and the handle is in an off position. To achieve these conditions, the stored energy motor operator includes a flag bearing on and off indicia, the flag attached to one end of a connecting bar, the other end of the connecting bar pivotally connected within the stored energy motor operator. A lever is attached to a central portion of the connecting bar at a spring, the lever including a hook portion for hooking onto a pin within the motor operator. When the contacts are closed, thus indicating an "on" condition, the lever remains hooked onto the pin. When the contacts are open, on-off indicator attached to a rotor drive pin within the circuit breaker moves the lever off of the pin. The connecting bar, however, does not move away from the pin until the handle is also in the off position and moves a second pin extending from the handle so that the connecting bar can move in its spring biased direction.
