CONTACT DEVICE, AND ELECTROMAGNETIC SWITCH USING SAME |
摘要 |
The present invention provides a contact device capable of narrowing a gap between a fixed contactor and a movable contactor and reducing the number of parts and the production costs, and an electromagnetic switch that uses this contact device. The contact device has: a pair of columnar fixed contactors (6a, 6b) which are fixed to a surface of an insulation airtight container (4) while keeping a predetermined space therebetween and each have at least a tip end contact surface protruding into the insulation container; a movable contactor (11) that is disposed so as to be capable of coming into contact with and separating from the pair of fixed contactors (6a, 6b); and a pair of arc extinguishing annular permanent magnets (9a, 9b) which are respectively attached to outer circumferential surfaces of the pair of fixed contactors (6a, 6b) and drive an arc outwardly. |
