Abstract: Conventional example is arranged simply to turn a circuit on/off, and not to changeover connection.Sealed relay 1 comprises: insulating tube 2; first relay connect portion 4 attached to one end of insulating tube 2, and provided with first contact 3 on inside surface; second relay connect portion 5 disposed in confrontation with first relay connect portion 4 in insulating tube 2; movable member 7 disposed movably between first and second relay connect portions 4 and 5, and provided with second contact 6 contacting with first contact 3 when moved toward the first relay connect portion; and operating mechanism to move the movable member. Third relay connect portion 10 including third contact 9 is provided between the second and first relay connect portions. Movable member 7 includes a fourth contact contacting with the third contact when the first and second contacts are out of contact from each other.

Abstract: In case of using multi-contacts or flat braided wires for constituting a current carrying structure of a movable part in a vacuum relay, problems tend to appear, which are enlargement of a control mechanism, complication, increased operation force and the like. The vacuum relay 1 includes an insulating cylinder 2, a first relay connecting portion 4 that is connected to one open end of the insulating cylinder 2 and has on its inner surface a first contact 3, a second relay connecting portion 5 that is arranged in the insulating cylinder 2 to face the first relay connecting portion 4, a movable member 7 that is movably arranged between the first and second relay connecting portions 4 and 5 and has a second contact that is brought into contact with the first contact when the movable member is moved toward the first relay connecting portion, and a control mechanism 8 that moves the movable member 7 in both directions to establish and break the contact between the two contacts. Between the movable member 7 and the second relay connecting portion 5, there is provided a bellows 11 through which the movable member 7 and the second relay connecting portion 5 are electrically connected.
