PROBLEM TO BE SOLVED: To provide a sealed contact device of high productivity, having small number of components.SOLUTION: In a sealed contact device, an annular flange 32a extending sideways from the edge of the lower opening of a metallic case 32 is welded to the upper surface of a planar yoke 37 integrally therewith and an internal space is formed, and a fixed contact 33a and a movable contact 48a are provided oppositely and separably in the internal space. In particular, an annular protrusion 32c provided along the lower surface of the annular flange 32a is integrated with the upper surface of a planar yoke 37 by resistance-welding. |
