An actuator (16) is allowed to move toward +A direction and toward -A direction. A movable contact (18) engages with the actuator. A fixed contact (726, 736) touch the movable contact with electrical connection when the movable contact is located at an ON position, and are apart from the movable contact with electrical isolation when the movable contact is located at positions other than the ON position. An arc prevention mechanism (19) prevents arc between the movable contact and the fixed contact. |
