摘要： A system may include a relay device that includes armatures associated with phases of voltage signals. The system may also include relay coils, such that each relay coil may receive a respective voltage that magnetizes a respective relay coil, thereby causing the respective armature to move from a respective first position to a respective second position. The system may also include a control system that receive an indication that a fault condition is present, identify a first phase of the phases of voltage signals that is expected to be the next phase of the phases to cross zero, and send a signal to the relay device in response to identifying the first phase. The signal is configured to cause a first relay coil of the relay coils to energize or deenergize.

摘要： An electromagnetic relay is provided with a housing; a first fixed contact terminal and a second fixed contact terminal secured to the housing; a movable contact accommodated in a chamber in the housing; a movable shaft with one end connected to the movable contact, and a solenoid configured to drive the movable shaft in a contact movement direction. A movable armature in the solenoid includes a groove that allows the movable shaft to be inserted from a direction intersecting with the contact movement direction. The other end of the movable shaft includes a first locking part and the groove in the movable armature includes a second locking part. The movable shaft and the movable armature engage in the contact movement direction with the engagement of the first locking part and the second locking part and move integrally in the contact movement direction.

摘要： A magnetic latching relay comprises a metal insertion portion of a contact portion and a slot of a base. The metal insertion portion is composed of two segments having different depth corresponding to the slot; when one segment is fitted to bottom wall of the slot, a preset gap is formed between the other segment and the bottom wall. The slot is formed by two segments having different thickness corresponding to the metal insertion portion; when two side walls of one segment of the slot are adapted to two sides of thickness of metal insertion portion, two side walls of the other segment of the slot and two sides of thickness of metal insertion portion respectively form a preset gap; one segment of metal insertion portions cooperates with the other segment of the slot, and the other segment of the metal insertion portion cooperates with one segment of the slot.

摘要： The movable body includes a pivot and a contact portion. The pivot is rotatably supported. The contact portion is disposed at a position contactable with a contact piece. The movable body rotates around the pivot and presses the contact piece via the contact portion to move the second contact close to the first contact. The actuator presses the movable body to rotate the movable body around the pivot. The contact piece has a curved portion located between the second contact and the support. The pivot is located on a side where the support is disposed with respect to the curved portion. The actuator includes a pressing member which presses the movable body. The pressing member moves in an axial direction of the pressing member to press the movable body.

摘要： Micro-electromagnetically actuated latched miniature relay switches formed from laminate layers comprising a spring and magnet, electromagnetic coils, magnetic latching material, and transmission line with contacts. Preferably the miniature relay switches transmit up to about 50 W of DC or AC line power, and carry up to about 10 A of load current, with an overall volume of less than about 100 mm3. In addition to switching large power, the device preferably requires less than 3 V to actuate, and has a latching feature that retains the switch state after actuation without the need for external applied voltage or current.

摘要： A GFCI includes a latch assembly provided with a rigid electrically conducting bar connected thereto such that when a user presses a reset button the latch assembly is moved toward a pair of contacts provided as part of a reset circuit to initiate a reset operation. When the electrically conducting bar on the latch assembly connects the pair of contacts, the reset circuit is closed and an actuator is activated to place the GFCI device in the latched, reset, condition. If the GFCI device is correctly wired, the latch assembly enters the latched state. If the device is not properly wired no power is provided to the actuator and the device remains in the tripped, or open, state.
