Various embodiments may include a coupling element for an electrical switching device comprising: a first switching contact at a first end of a winding body; a second switching contact; and a rotating body through which the winding body extends. The rotating body rotates on the winding body and the winding body translates along its longitudinal axis. A cord is arranged on each of the two sides of the rotating body between the rotating body and the winding body so that winding and unwinding of the cord is caused by opposite rotational movements of the rotating body driving a translational movement of the winding body. The rotating body is coupled to two springs so that a spring force always acts on the rotating body in both directions of rotation. A lock blocks the rotating body in at least two extreme positions of the translational movement of the winding body.
