Abstract
An electrical switching device () which comprises at least one double breaking pole provided with two fixed contacts () that cooperate with two moving contacts () arranged so as to move in a breaking plane (P) and define, with every fixed contact, a breaking zone. The device comprises a permanent magnet () housed in an insulating holder arranged in the immediate environment, next to each breaking zone, symmetrically with respect to the breaking plane and oriented so as to generate a magnetic excitation vector parallel to the breaking plane (P) so that the induced electromagnetic force (FE) moves and stretches every electric arc (E, E), generated when opening the electrical circuit, in a direction perpendicular to the breaking plane (P), leading to the extinction of the electric arc regardless of the polarity of the magnet and/or of the current.
