Coupling element for an electrical switching device

A coupling element for an electrical switching device, the element comprising:

• a first switching contact for opening and closing an electrical contact;
• a second switching contact;
• a rod-shaped winding body with a longitudinal axis, wherein the first switching contact is arranged at one end of said winding body;
• a rotating body through which the winding body extends,
• the rotating body including two sides with a first side facing one end of the winding body and a second side facing the other end of the winding body;
• wherein the rotating body is mounted to rotate on the winding body and the winding body is mounted to translate along the longitudinal axis;
• a cord 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 on the winding body is caused by opposite rotational movements of the rotating body driving a translational movement of the winding body;
• two springs coupled to the rotating body so that a spring force always acts on the rotating body in both directions of rotation;
• and
• a lock blocking the rotating body in at least two extreme positions of the translational movement of the winding body.
