Abstract (en)

[origin: WO2021001471A1] Switching contact system (1.1; 1.2; 1.3; 1.4; 1.5; 1.6) for a switching system consists of a first contact piece (7) and a second movable contact piece (8). A conductive contact piece support (2.1; 2.2; 2.3; 2.4; 2.5; 2.6) is electrically connected to a second electrically conductive component (10.1; 10.2; 10.3; 10.4; 10.5). One ferromagnetic element (11; 11') is spaced apart from the contact piece support (2.1; 2.2; 2.3; 2.4; 2.5; 2.6). In an operating state, at a short-circuit, the contact piece support (2.1; 2.2; 2.3; 2.4; 2.5; 2.6) is bent such an attraction force is caused that moves the second movable contact piece (8) such that an initial electrical contact point between the second movable contact piece (8) and the first contact piece (7) is shifted and any existing sticking points are broken up.
