摘要： An interrupter system includes a first coil and an interrupter electrically connected to the first coil. The interrupter includes: a first terminal; a second terminal electrically connected to the first terminal; a third terminal electrically separated from the first terminal and the second terminal; a heat generating element electrically connected to the third terminal; and an explosive configured to be ignited by the heat generating element to produce a gas for interrupting an electrical connection between the first terminal and the second terminal. The first coil is electrically connected to the heat generating element via the third terminal. Moreover, the first coil is configured to, when an abnormal current flows between the first terminal and the second terminal, generate an electric power for igniting the explosive from the abnormal current.

摘要： A high voltage relay resistant to instantaneous high-current impact is disclosed, and includes an electromagnet system, a control system, a contact system, and a base support. In the present solution, an electromagnetic force generated by the contact system is used to resolve a problem of contact separation caused by an electric repulsion force generated by an instantaneous high-current.

摘要： This disclosure relates to ingress-tolerant input devices. Aspects of the disclosure relate to an ingress-tolerant switch assembly for operating an electronic device in an ingress-protected manner. The switch assembly includes a button configured to be coupled to an outer surface of an enclosure of the electronic device. The switch assembly also includes a spring operably coupled to the button and a magnet coupled to the spring. A pressing force applied by a user to the button overcomes a spring force of the spring to move the magnet into proximity of the magnetic sensor to cause the magnetic sensor to generate a sensor signal for performing a function of the electronic device.

摘要： Systems of automatic transfer switches (ATS) are disclosed herein. One apparatus includes at least two automatic transfer switches coupled together. Each automatic transfer switches has contacts to couple a power source to a load. For each switch, an electromagnetic force biasing the contacts to each other is present if an electrical current flows through the switch. The automatic transfer switches may be on separate cassettes or on a single cassette. The power source of each switch may be the same or different.

摘要： An electromagnetic relay has a contact device and an electromagnet device. An electromagnetic relay has stators which are a pair of rod-like members, and a mover. The mover may face the side of the stator. A housing supports the stator and accommodates the mover. A yoke is fixed to the housing so as to face the movable facing surface and contains a soft magnetic material.

摘要： A contact device includes a moving contactor, a pair of moving contacts arranged in one direction, a pair of fixed terminals, and a pair of fixed contacts. At least one fixed terminal, selected from the pair of fixed terminals, includes a contact holder. The contact holder includes a first fixed extension and a second fixed extension. As for either a current component flowing in the one direction into the fixed contact or a current component flowing in the one direction out of the fixed contact, the current component flowing through the first fixed extension has a larger amount of current than a current component flowing through the second fixed extension.

摘要： A keyswitch structure includes a base plate, a keycap, a lift mechanism connecting the keycap and the base plate, a movable part movably disposed relative to the base plate, a linking support, and a magnetic part on the base plate. The linking support has a pivotal connection portion, a magnetic portion, and a driving portion. The magnetic part and the magnetic portion produce a magnetic attraction force therebetween. When the movable part is located at a first position, the pivotal connection portion is rotatably disposed on a protruding portion of the movable part, and the magnetic attraction force drives the keycap through the linking support to move away relative to the keycap. When the movable part moves from the first position to a second position, the protruding portion moves away, so that the pivotal connection portion falls down and the keycap moves toward the base plate.
