Abstract
A travelling mechanism for a withdrawable circuit-breaker includes a crank handle that is secured in a manner that prevents it from being removed. A shaft of the crank handle revolves around an input shaft and is guided in a manner that permits it to be displaced in relation thereto. An accommodating recess holds the crank handle in its inoperative position. In its working position, the crank handle can only be pulled out when a locking lever that is dependent on the switching position of the circuit-breaker releases a locking slot on the shaft of the crank handle. In the working position, the crank handle is secured by a locking slide. An indicating device for indicating the position of the circuit-breaker comprises a two-armed indicating lever, which is provided with a window opening that permits the entry of a tongue of the locking slide in the test position.
