  • Patent number: 10207732
    Abstract: A steering column switch for a vehicle includes a switching lever that operates by pivoting in relation to a housing. The lever has a locking pin which assumes a stable position on a switching gate when the lever is not operated and is guided into an unstable position by operation of the lever. The switching gate guides the pin back into the stable position when operation of the lever ceases. A permanent magnet on a body of the lever is brought against an electromagnet on the housing by pivoting the lever into the unstable position. The lever is held in the unstable position by magnetic attraction between the magnets for a time in which a function associated with the lever being actuated into the unstable position is active. Afterwards, the electromagnet produces a counter magnetic field which interrupts the magnetic attraction so that the lever returns to the stable position.

  • Patent number: 10192701
    Abstract: An actuation apparatus includes a module movably tethered to a base member. Each of the module and base member include a plurality of magnetic elements aligned in a plurality of paired magnet sets such that in a non-actuated condition a repulsive magnetic force generated by each paired magnet set causes separation of the module and base member. Application of an actuation force to an actuation surface of the module, in opposition to the magnetic repulsive force, causes movement of the module toward the base member such that contact is made between terminals defined by the magnetic elements of at least one of the paired magnet sets, to generate an output signal. In an illustrative example, the base member is a steering wheel armature of a vehicle and the module is a wheel hub assembly including an air bag and a hub cover defining the actuation surface.

  • Patent number: 10181387
    Abstract: An electromagnetic repulsion actuator for a circuit breaker is provided. The actuator can include a housing; a first fixed electrode having therein an operating space open at both sides; a pair of movable electrodes capable of reciprocally moving and being electrically connected to the first fixed electrode; second fixed electrodes selectively contacting the pair of movable electrodes to be electrically connected thereto, thereby transferring power supplied from a first side to a second side; and actuating coils selectively moving the movable electrodes in a direction of being separated from the second fixed electrodes by generating electromagnetic force from induced current. In the present invention as above, the structure of a circuit breaker is simplified and moving speeds of the movable electrodes are increased since the movable electrodes move by using induced current generated by a close coil and open coils to perform an open operation.
