The present invention relates to a switching device with at least one contact point and the contact point associated Lichtbogenblaseinrichtung, wherein the Lichtbogenblaseinrichtung at least one blow-out magnets for generating a magnetic blowout field, and wherein the blowout field is arranged such that an emerging when opening the contact point switching arc from the contact point blown becomes. The blowout field has a first magnetic field region and a disposed adjacent to the first magnetic field region second magnetic field on, wherein magnetic field lines of the first magnetic field region oriented opposite to the magnetic field lines of the second magnetic field region, and wherein the blowout field further comprises a transition portion which connects the first magnetic field region and the second magnetic field region together wherein the orientation of the magnetic field lines in the transition region, starting equalize each of the first magnetic field region and the second magnetic field region, the contact point towards, so that the switching arc within the transition region in dependence of the current direction from the contact point in either the first magnetic field region or in the second magnetic field region passed and there is blown away in both cases in the same direction from the contact point. The Lichtbogenblaseinrichtung has a first side pole piece, a second lateral pole plate and an interposed middle pole plate, wherein the first magnetic field region between the first side pole plate and middle pole plate, and wherein the second magnetic field region between the second side pole plate and middle pole plate, wherein the average is at least pole plate facing a first end of the contact point is shorter than the two side pole plates. According to the invention it is provided that the mean pole plate at a first end thereof opposite second end is also shorter than the two lateral pole plates.
