Abstract

A switch for multi-pole direct current service independent of polarity includes a plurality of switching chambers. Each chamber includes a double interrupter having two separate fixed contacts with a first contact area, a movable contact piece with two second contact areas, each for creating a connection between the contact areas in an ON state and for separating the contact areas in an OFF state, and at least two quenching devices for quenching arcs occurring when the OFF state is brought about. The switch also includes magnets for exerting a magnetic field in an area of the contact areas to exert a magnetic force on the arcs and drive the arcs, independent of their current direction, in the direction of one of the erasing devices. The contact pieces are disposed with the second contact areas essentially in a line perpendicular to a direction of motion of the arcs.
