Problems solved by technology
Depending on the geometry of the switching chamber, the arc can burn permanently at specific points (e.g. at the ends of the guide rails), which correspondingly prolongs the arc burning time and thus correspondingly increases the thermal load on the switching chamber, which shortens the service life of the switch

Embodiment Construction
[0030] figure 1 A switch chamber 1 of a switch according to the invention is shown in transverse section, which has a first embodiment of an interrupter arrangement 21 according to the invention. In order to guide a not shown arc formed between the first contact 9 and the second contact 18 when the contacts 9, 18 separate, two guide rail structures are provided, a first guide rail structure 37 and a second guide rail structure 38. The function of the first guide rail structure 37 is to guide the arc with the first current direction at the arc extinguishing device (here the arc extinguishing plate structure 21 according to the invention). The function of the second guide rail structure 38 is to guide an electric arc with a second reverse current direction in the same arc chute structure 21 . A corresponding switch with a plurality of switching chambers 1 is described in detail in EP 2 747 109 A1 and will not be described in detail here.
