    • A sealed receptacle includes a case, a cylindrical member, and a closure plate. The sealed receptacle is configured to house a fixed contact, a movable contact, and an arc protection member. The arc protection member includes a peripheral wall, and a bottom. The peripheral wall is configured to conceal a junction between the case and the cylindrical member from the fixed contact and the movable contact. The bottom is interposed between the movable contact and the closure plate. The sealed receptacle houses a contact pressure provision member configured to bias the movable contact to come into contact with the fixed contact. The contact pressure provision member is interposed between the movable contact and the bottom so as to come into resilient contact with both the movable contact and the bottom irrespective of a position of the movable contact.
