<p>A sealed receptacle (20) includes a case (21), a cylindrical member (22), and a closure plate (23). The sealed receptacle (20) is configured to house a fixed contact (31), a movable contact (40), and an arc protection member (60). The arc protection member (60) includes a peripheral wall (61), and a bottom (62). The peripheral wall (61) is configured to conceal a junction between the case (21) and the cylindrical member (22) from the fixed contact (31) and the movable contact (40). The bottom (62) is interposed between the movable contact (40) and the closure plate (23). The sealed receptacle (20) houses a contact pressure provision member (51) configured to bias the movable contact (40) to come into contact with the fixed contact (31). The contact pressure provision member (51) is interposed between the movable contact (40) and the bottom (62) so as to come into resilient contact with both the movable contact (40) and the bottom (62) irrespective of a position of the movable contact (40).</p> |
