There is provided a sealed contact device capable of enabling a movable contact member to move smoothly. A sealed contact device includes an electromagnet block 2 including a coil bobbin 21, a movable iron core 25, a yoke 26, and a return spring 27; a contact block 3 including a sealing container 31, fixed contact points 32, a movable contact member 35 arranged within the sealing container 31 and composed of a substantially rectangular body portion 35a, first and second protrusions 35b, 35c formed in longitudinal sides of the body portion 35a and movable contact points 34 for making movement toward and away from the fixed contact points 32, and a shaft 37 connected to the movable contact member 35 at one end and to the movable iron core 25 at the other end to move the movable contact member 35 toward the fixed contact points 32; and a case 4. The first and second protrusions 35b, 35c of the movable contact member 35 are formed in non-point symmetry with respect to a connection portion of the movable contact member 35 and the shaft 37 so that, when the movable contact member 35 is rotated, only one of the first and second protrusions 35b, 35c makes contact with the sealing container 31. |
