<p>The present invention is provided with: a fixed contact (32); a movable contact (33) which comes in contact with and separates from the fixed contact (32); and a drive means which has at least an electromagnetic coil and drives the movable contact (33) so that the movable contact comes into contact with the fixed contact (32). The drive means generates a first driving force for bringing the movable contact (33) into contact with the fixed contact (32), and a second driving force, which is larger than the first driving force, for maintaining the contact state between the movable contact (33) and the fixed contact (32).</p> |
