Abstract (en)
[origin: WO2017032508A1] The contact device (30) for the electrical switch comprises a first connection element (31), a second connection element (32) and a movable contact bridge (33). Furthermore, the contact device (30) comprises at least two magnets for extinguishing arcs which arise during the switching of the electrical switch. The magnets generate a magnetic field in a first region which comprises at least one first contact region and one second contact region, in which contact regions, with the electrical switch in a closed switching position, the first connection element (31) and, respectively, the second connection element (32) are in contact with the contact bridge (33). In addition, the contact device (30) comprises one or more deflection elements which are arranged and designed to distort the magnetic field in such a way that a first arc which forms between the first connection element (31) and the contact bridge (33) and a second arc which forms between the second connection element (32) and the contact bridge (33) are forced into different directions, which extend pointing away from one another, independently of a respective flow direction in the connection elements (31, 32).
