PROBLEM TO BE SOLVED: To realize a direct current high voltage control relay which is applied for cutting off both circuits simultaneously and has a long life. SOLUTION: A first and a second open-close parts 11, 20 are arranged in parallel on Y2 side of a base 100, and an exciting coil unit 105 is fixed to Y1 side of the base 100. First and second permanent magnet pieces 30, 40 are insert-molded into a case, and the first and second permanent magnet pieces 30, 40 are respectively arranged upward the first and second open-close parts 11, 20. Both in the first and second permanent magnet pieces 30, 40, the N electrode is opposed to the first and second open-close parts 11, 20. This is used by connecting the first open-close part 11 to an anode of a direct current power supply and a load, and by connecting the second open-close part 20 to a cathode of the direct current power supply and the load. Arc generated in the first and the second open-close part 11, 20 is blown away outside and arc-extinguished. By a single relay, both of a first circuit wiring and a second circuit wiring can be cut off simultaneously. COPYRIGHT: (C)2009,JPO&INPIT
