A movable electrode with a movable contact at one end and driven in the axial direction, a cylindrical part through which the movable electrode is inserted, a bellows with one end fixed to the movable electrode and the other end fixed to the cylindrical part, and a magnetic flux that is movable. A sealed contact device comprising: a permanent magnet disposed perpendicular to the axial direction of the electrode so that the flow passes through a movable contact and a fixed contact; and a yoke surrounding the permanent magnet to form a magnetic path. A sealed contact device characterized in that a yoke is electrically insulated from the movable contact and the fixed contact. (2) The sealed contact device according to claim (1), wherein the yoke forms a magnetic path on a surface perpendicular to the axial direction of the movable electrode.
