Abstract

A switching device having at least one contact pair includes a first contact and a second contact, where at least the second contact is movable relative to the first contact. There is an extinguishing device with at least one extinguishing chamber for extinguishing an arc produced between the contacts, a first guide rail arrangement for guiding the arc with one direction of current and a second guide rail arrangement for guiding the arc with the second direction of current in said extinguishing chamber. Both guide rail arrangements have a first guide rail and a second guide rail, where both first guide rails starting from the first contact run in the opposite direction, and both second guide rails starting from the second contact run in the opposite direction. The first guide rails are connected with each other in an electrically conductive arrangement in the form of a closed loop.
