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： A relay includes an insulating cover having a contact chamber and a pair of first through holes in communication with the contact chamber; a pair of static contact leading-out terminals passing through the pair of first through holes; a fixing member including a fixing part and a connector with a tubular structure, the connector is fixedly connected between the insulating cover and the fixing part; a moving part within the contact chamber and movably connected to the fixing member; a first magnetizer within the contact chamber and connected with the moving part; and a movable member within the contact chamber and including a movable contact piece. The first magnetizer is movable relative to the movable member through the moving part and is configured to adjust a distance between the first magnetizer and the movable member according to a value of a current flowing through the movable contact piece.

摘要： An electromagnetic relay includes a fixed contact, a movable contact piece, a movable contact, a contact case, a drive device, and an elastic member. The movable contact is disposed to face the fixed contact. The movable contact piece is connected to the movable contact. The movable contact piece is configured to move in an opening direction and a closing direction. The contact case houses the fixed contact, the movable contact, and the movable contact piece. The drive device includes a coil. The coil generates an electromagnetic force that moves the movable contact piece. The elastic member is disposed between the drive device and the contact case. The elastic member seals between the drive device and the contact case.

摘要： A magnetic switch apparatus for detecting relative movement between first and second members comprises a switch assembly, a magnetic actuator, and an enclosure. The switch assembly mounts on the first member and is configured to shift between states. The magnetic actuator mounts on the second member and is configured to shift the switch assembly between states when the members change positions. The enclosure houses the switch assembly or the magnetic actuator on its respective member and includes a coupling structure configured to decouple from the respective member when the enclosure is shifted in a direction away from the respective member. The direction is at least partially toward the other member when the members are in a close position.

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： An electromagnetic relay includes a fixed contact, a movable contact, a movable contact piece, a case, and an adhesive material. The movable contact is disposed to face the fixed contact. The movable contact piece is connected to the movable contact. The movable contact piece is movable between a closed position in which the movable contact is in contact with the fixed contact and an open position in which the movable contact is separated from the fixed contact. The case accommodates the fixed contact and the movable contact. The adhesive material is disposed in the case. The adhesive material captures foreign matter in the case.

摘要： A mechanical latching device of an electromagnetic contactor eliminates a need to adjust a gap between portions mechanically preventing returning of a latch support. A latch support includes a protrusion protruding laterally and formed with a latch surface facing a released side. A rotating member has one end side rotatably supported and the other end side biased toward the protrusion. When the latch support is on the released side, an outer peripheral surface of the other end side contacts with a tip of the protrusion to allow the latch support to be displaced to a closed side. When the latch support is on the closed side, the other end side rotates according to a position of the latch support in a displacement direction, and a tip surface faces the latch surface to mechanically prevent the latch support from returning to the released side at plural positions along the displacement direction.
