<P>PROBLEM TO BE SOLVED: To surely prevent connection between a fixed contact and a movable contact due to vibration from outside, and the resulting flow of a high voltage current when it is to be cutoff. <P>SOLUTION: A movable armature 250 comprises: a first movable contact 206 arranged opposite a first fixed contact 202; and a second movable contact 207 arranged opposite a second fixed contact 203. The movable direction of the first movable contact 206 in contacting the first fixed contact 202 is opposite to the movable direction of the second movable contact 207 in contacting the second fixed contact 203. First elastic members 210a, 210b, arranged between an enclosure 201 and the movable armature 250, support the movable armature 250 in the enclosure 201 without contact between the first movable contact 206 and the first fixed contact 202 and without contact between the second movable contact 207 and the second fixed contact 203, while enabling the movable armature 250 to move by elastically deforming themselves, during cutoff of a high voltage current. <P>COPYRIGHT: (C)2013,JPO&INPIT |
