Abstract
A sealed contact device having a small number of components and high productivity. In the sealed contact device a ring-shaped flange portion extending laterally from a lower opening edge part of a metallic case is welded and integrated with an upper surface of a plate-shaped yoke to form an internal space and a stationary contact and a moving contact are opposed to each other in the internal space so as to enable approach/separation. A ring-shaped projection provided along a lower surface of the ring-shaped flange portion is integrated with the upper surface of the plate-shaped yoke by resistance welding.
