Abstract (en)
[origin: EP2284340A2] The catch has magnets (4) attached to a fixed part (2), where the magnets sealed with a yoke (3) comprise a permanent magnet (5). Magnetic field closure is generated within the former magnets by switching magnets (7) that connect pole shoes (6) of the former magnets. Magnetization direction of the switching magnets runs along the connection of the shoes. The switching magnets are magnetized to change magnetic field discharge of the former magnets. The shoes are detected by measurement of a sensor e.g. winding (8), coil (9) and Hall sensor or giant magnetoresistance (GMR) sensor (11). The sensor is arranged as a Hall sensor or giant magneto-resistance (GMR) sensor or as a resistance strain gauge. The switching magnets comprise aluminum nickel and cobalt magnetic substance.
