Abstract

A switching device for direct current applications having a first switching chamber for a first current path and a second switching chamber for a second current path, each current path having a switching contact arrangement having a first and second contact, wherein both the contacts, switched-on, come into contact with each other and, switched-off, are kept out of contact with each other by the creation of an isolation gap; a current path having an extinguishing device to extinguish an arc created between the contacts; an arc driver arrangement, arranged in one of the two switching chambers, and which creates a magnetic field at least in the area of the switching contact arrangement for the relevant current path that drives the arc into the relevant extinguishing device.
