• a movable member including a pressure reception member and located at a position on an opposite side of the contact piece from the specific surface of the base member in the operation directions,
• the movable member including a through hole which is located in an area surrounding the pressure reception member and penetrates the movable member in the operation directions,
• the contact piece including a support part supported on the base member, a movable contact part movable between a position in contact with the fixed contact part and a position separate from the fixed contact part, and an interconnection part interconnecting the support part and the movable contact part,
• the contact piece being configured so that, when the pressure reception member is pushed to be moved closer to the specific surface of the base member to cause change in shape of the movable member, the interconnection part is pushed by the movable member and the movable contact part is moved along the operation directions, and
