A direct current switch with a device for arc extinction independent of current direction includes at least two interconnected switch units, each switch unit having at least one current path having an interruption surface and having at least two switch contact elements for forming the interruption surface. An arc extinction device is associated with one or a plurality of current paths of the switch units. Devices for magnetic field generation are included, each generated magnetic field being assigned to different switch units' interruption surface and oriented such that its field lines run transversally to the respective interruption surface. Given a current flow direction, deflection forces of at least two generated magnetic fields act through flow paths contrary to arcs extending longitudinally to respective interruption surface such that an arc is deflected towards the arc extinction device and a further arc is deflected away from the arc extinction device. |
