摘要： An electromagnetic relay includes a case including a base, a first fixed terminal held by the base, a movable contact piece, a gas inflow space, and a gas passage. The first fixed terminal includes a first fixed contact disposed apart from the base in a first direction inside the case, a contact support portion disposed between the first fixed contact and the base and configured to support the first fixed contact, and a first extending portion extending at an angle from the contact support portion and penetrating the base in the first direction. The movable contact piece includes a first movable contact facing the first fixed contact in the first direction. The gas inflow space is formed between the base and the contact support portion inside the case. The gas passage penetrates the base in the first direction and communicates the gas inflow space with an outside of the case.

摘要： A relay device includes: a first contact and a second contact; a driving mechanism; a first conductor; a second conductor; and a static relay and an electric heating element. The driving mechanism is configured to cause the first contact and the second contact to be close to each other or separated from each other. The first conductor is electrically coupled to the first contact. The second conductor is electrically coupled to the second contact. The static relay and an electric heating element are coupled between the first conductor and the second conductor. The electric heating element is disposed to allow heating of one or both of the first contact and the second contact.

摘要： Provided is an electromagnetic relay which can sufficiently dissipate heat generated from a coil to secure desired attracting force even when the electromagnetic relay is miniaturized. The electromagnetic relay includes an electromagnet block and a contact switching mechanism. A movable contact piece of the contact switching mechanism includes a contact attaching portion to which a movable contact is attached, and a first fixed portion attached to a first movable iron piece of the electromagnet block. The first fixed portion is in surface contact with the movable iron piece and is substantially equal in width dimension to the movable iron piece.

摘要： The present invention relates to an electrically operated switch, and particularly to an electrically operated switch for long-term use comprising a first electrically conductive heat-dissipating fin, a second electrically conductive heat-dissipating fin, and a plurality of relays. All the input terminals on the plurality of relays are interconnected through the first electrically conductive heat-dissipating fin, and all the output terminals on the plurality of relays are interconnected through the second electrically conductive heat-dissipating fin. In the present invention, the plurality of relays is interconnected through a first electrically conductive heat-dissipating fin and a second electrically conductive heat-dissipating fin. The first electrically conductive heat-dissipating fin and the second electrically conductive heat-dissipating fin may not only perform electrical conduction but may also speedily dissipate heat from the contacts on the plurality of relays to allow the plurality of relays to operate under long-term high current flow without getting burned.

摘要： A system includes first and second relays which physically adjoin one another and are controlled such that one of the relays is off whenever the other relay is on. In operation, heat generated in the first relay thermally conducts to the second relay where the relays physically adjoin one another whereby the second relay functions as a heat sink for the first relay while the second relay is off and the first relay is on. Correspondingly, in operation, heat generated in the second relay thermally conducts to the first relay where the relays physically adjoin one another whereby the first relay functions as a heat sink for the second relay while the first relay is off and the second relay is on.
