Abstract
A series connection of an auxiliary switching position and a cut-on resistor is connected parallel to at least one primary switching position. A common drive rod is provided with which there is coupled a transmission system operatively associated with the primary switching position as well as a transmission system operatively associated with the auxiliary switching position. The transmission system associated with the auxiliary switching position comprises a cam cooperating with a follower or entrainment member mounted to an actuator rod leading to the auxiliary switching position. For positively controlling the sequence of movements without having to tension a spring during the cut-on of the auxiliary switching position the cam comprises a stationary cam or guide track containing a closed loop engaged by the follower member. Additionally, the follower member traverses an elongated hole of a bracket or cantilever connected with a longitudinally reciprocatable drive rod and extending parallel to the plane of the cam or guide track. The elongated hole extends transversely with respect to the direction of movement of the drive rod at least across the width of the closed loop. The foll…
