An electromagnetic relay includes: an exciting coil; a movable core driven by the exciting coil; a movable contactor having a first movable contact and a second movable contact to operate with the movable core; a first fixed terminal having a first fixed contact with which the first movable contact abuts when the movable contactor is moved by energizing the exciting coil; and a second fixed terminal having a second fixed contact with which the second movable contact abuts when the movable contactor is moved by energizing the exciting coil. An inclination angle of a central axis of the first movable contact with respect to a central axis of the first fixed contact and an inclination angle of a central axis of the second movable contact with respect to a central axis of the second fixed contact are inclined in opposite directions from each other.

An electromagnetic relay includes a fixed spring, a fixed contact configured to be swaged so as to be attached to the fixed spring, a movable spring, and a movable contact provided on the movable spring so as to be capable of making contact with the fixed contact, wherein a swaged portion of the fixed contact is formed so as not to protrude from a surface of the fixed spring.

An electrical contactor, and more particularly, but not exclusively, contactors having improved noise performance.

A relay includes a case and a coil unit is located in the case. Multiple first legs each have the first end thereof connected to the coil unit, and the second end thereof extending beyond the case. A second leg has the first end thereof located in the case and forms a contact, and the second end of the second leg extends beyond the case. A third leg includes an upright section and a transverse section which extends from the upright section and located in the case. The upright section has one end thereof extending beyond the case. An armature has a connection section connected to the transverse section, and a main section located beneath the contact. The connection section increases conductive area and flexibility of the armature in the case.

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.
