Abstract
A contactor for switching electric current has a stationary contact and a movable contact which when driven by a solenoid moves into and away from abutment with the stationary contact. An arc extinguishing chamber is adjacent to the movable and stationary contacts and includes two rows of splitter plates with a gap therebetween. Each row comprises alternating splitter plates of first and second types. The first type of splitter plate has a first member of non-magnetic material with an aperture within which a permanent magnet is received and a second member of a magnetic material abutting the first member remote from the gap. An outer casing of a non-ferrous, electrically conductive material extends at least partially around the first and second members. The second type of splitter plates are formed of non-ferrous, electrically conductive material. The magnets produce a magnetic field around each of the first type of splitter plates which causes the electric arc to move about the surface of the outer casing.
