Abstract
A DC contactor has stationary and movable contacts. A magnet is rotatably mounted adjacent to the stationary contact within a self magnetic field produced by the flow of electric current in the stationary contact. The magnet rotates so that its magnetic field extends around the stationary contact in the same direction as the self magnetic field. When an arc forms between the stationary and movable contacts, interaction with the self magnetic field and the magnetic field drives the arc toward an adjacent extinguishing chamber.
