摘要： A switching machine comprises a frame, a point detector bar, an indication contact assembly, at least one detector bar follower able to act on the indication contact assembly depending on the position of the point detector bar relatively to the frame, an inhibiting element jointly movable with the detector bar follower, and a cam bar translatable relatively to the frame between an unlock position and a lock position. The cam bar comprises a tongue portion which is able to be in contact with a stop of the inhibiting element when the cam bar is in its unlock position and to be away from the stop when the cam bar is in its lock position. The inhibiting element comprises a main body relatively to which the stop is vertically translatable between an active position and a passive position.
