Abstract (en)
The system has a contact arm (10) supported in a switching shaft (2) and for each pole in a switch housing around a pivotal point (12). A contact force spring (20) acts on an axle of a spring catch (30) at the arm by the catch that is supported in a support (24). The area is shifted during opening movement, so that a force vector is deviated by the pivotal point of the arm. The spring lies between a spring pivot (22) in the shaft and the support, where the support is guided on a circular arc in a longitudinal-relocating manner.
