| Zusammenfassung: | In the contact apparatus of the present invention, a permanent magnet (32) is disposed in a region where a fixing contact point (7) mounted tot he fixing contact (3) and a movable contact (8) to which the movable contact point (9) is mounted. An arc (34) generated between both the contact points (7, 9) is moved sideways by the magnetic force of the permanent magnet (32) and stretched. An arc-extinguishing member (31) which is heated by the arc (34) for generating arc-extinguishing gas is provided such as to surround the fixing contact point (7) and the movable contact point (9). With this structure, the arc voltage of the arc (34) generated between both the contact points (7, 9) abruptly rises, the arc is swiftly extinguished, and the breaking performance of an electric path is enhanced. |
