摘要： An electromagnetic relay includes a contact device, a movable member, a driving device, a return spring, and an insulating member. The contact device includes a first fixed terminal, a second fixed terminal, and a movable contact piece. The movable member presses the movable contact piece. The driving device is disposed on one side of a first direction with respect to the contact device and the movable member and moves the movable contact piece via the movable member to one side of a second direction intersecting the first direction. The return spring is disposed between the movable member and the driving device in the first direction for urging the movable member toward another side of the second direction. The insulating member separates the contact device from the driving device and has an opening where the return spring is inserted. The opening is open toward one side of the first direction.

摘要： An electromagnetic energy converter for a remote switch. The energy converter has an electrical coil and magnetic components, which comprise at least one permanent magnet and at least one ferromagnetic element. The permanent magnet and/or the ferromagnetic element are each movable between two extreme positions, where the movement of the permanent magnet and/or of the ferromagnetic element between the extreme positions leads to a directional reversal of a magnetic flux in the magnetic circuit. The magnetic flux is enclosed at least in part by the coil. At least one of the extreme positions is configured as a contactless extreme position at which at least two of the magnet components do not contact.

摘要： A relay switch (42) for a relay (10) is provided which comprises a first terminal (14a, 14b), a second terminal (16a, 16b), and a switching arm arrangement (36) between the first and second terminals (14a, 14b, 16a, 16b) which forms a first electrical conduction pathway in a contact condition of the switching arm arrangement (36). An electrical conductor (49) is also arranged between the first and second terminals (14a, 14b, 16a, 16b) which forms a second electrical conduction pathway in the contact condition in parallel to the first electrical conduction pathway.

摘要： An electromagnetic relay includes a base, a casing, a coil, a movable contact piece and two fixed contact pieces. Each of the fixed contact pieces includes a plate-shaped base. A portion of one side of the plate-shaped base extends outward and is bent to form a fixed contact fixing part. The fixed contacts are arranged on the fixed contact fixing part, and an abdicating through hole is defined in the base. The plate-shaped bases of the fixed contact pieces are respectively connected to an outer side surface of the base and spaced from each other. Each of the fixed contact fixing parts protrudes through the abdicating through hole and located between the base and the casing. Each of the fixed contacts faces to the movable contact on the movable contact piece, and a portion of the plate-shaped base on the fixed contact piece protrudes out of the casing to form a connecting part.

摘要： Switch device including a switch and a bypass mechanism and a method of manually operating the switch. The switch includes a first terminal, a second terminal, a contact member configured to be in a first position and a second position and to form a connection between the first terminal and the second terminal when in the first position or in the second position, and a control unit configured to facilitate a transition of the contact member and to retain the contact member at the first position or at the second position in the absence of an external force. The bypass mechanism includes at least one moveable member having a first surface configured to contact the contact member at a first angle that is acute or obtuse. Energy generation and/or storage systems contain the switch device, and methods of controlling connection of these systems to a power grid and/or a load.

摘要： An electromagnetic relay includes a case, a movable contact piece, a fixed terminal, a driving device, and an insulating wall. The movable contact piece includes a movable contact. The fixed terminal includes a fixed contact, a contact support portion, an extension portion, and a bent portion. The contact support portion supports the fixed contact. The extension portion extends from the contact support portion in a longitudinal direction of the movable contact piece. The bent portion extends in a bent shape from the extension portion in a first direction from the fixed contact toward the movable contact, and overlaps the movable contact piece in the longitudinal direction of the movable contact piece. The driving device is configured to move the movable contact piece. The insulating wall is integral with the case and is disposed between the bent portion and the movable contact piece.

摘要： A method for determining contact thickness change in a contactor includes sensing a first displacement distance moved by an armature of the contactor from a reference location to a first transition point during a switch-off operation of the contactor at a first contactor life reference time when movable contacts and fixed contacts of the contactor define a first contact thickness. The method further includes sensing a second displacement distance moved by the armature from the reference location to a second transition point during a switch-off operation at a second contactor life reference time that is after the first contactor life reference time when the movable and fixed contacts define a second contact thickness that is less than the first contact thickness. The first displacement distance and the second displacement distance are used to determine a contact thickness change between the first contact thickness and the second contact thickness. A contactor adapted to implement the method is also disclosed.
