When a movable contactor is rotated without a rotation axis, a fluctuation of a rotation center of the movable contactor is not generated and a current limiting function is fast performed. Also, after contacts are separated from each other, the movable contactor is prevented from returning towards fixed contactors and the separated position is maintained for a predetermined time. An assembly process of the contactor assembly is simplified.
