Summary:A fixed electrode 10 and a movable electrode have coil electrodes formed of plural coil portions installed at both contacts and on a rear surface side in a divided manner in a circumferential direction along peripheries of the contacts such that a longitudinal field is generated in a direction in which the fixed contact and the movable contact come close to and move apart from each other. Protruding portions joined to the contacts are provided to tip ends of the respective coil portions to form joint portions to the respective contacts. A current to be flowed is controlled by changing resistance values between the contacts and the coil electrodes for each joint portion.
