1. A switching device, comprising two fixed contacts and one movable contact in a switching chamber, wherein
the fixed contacts are arranged in juxtaposition along a longitudinal direction,
the switching chamber has a switching chamber wall with opposing transversal sidewall parts and with opposing longitudinal sidewall parts,
each of the two fixed contacts has a distance (T) to one of the transversal sidewall parts which is smaller than a respective distance (L) to the longitudinal sidewall parts,
wherein the fixed contacts and the movable contact are arranged along the longitudinal direction between permanent magnets,
wherein the switching chamber comprises at least one web which is arranged in longitudinal direction between the at least two fixed contacts and which extends from at least one longitudinal sidewall part in transversal
direction into the switching chamber.
