  • Position switch
    Patent number: 7893802
    Abstract: A position switch is disclosed with a device to generate a magnetic force, with at least a first coil and at least one armature, it being possible to magnetize and move the armature via the first coil. How the magnetic force, particularly at the start of movement of the movable components of the device, can be increased to reduce the necessary power consumption of the first coil, is a focus of at least one embodiment. For this purpose, at least one embodiment of the device to generate a magnetic force includes at least one device to premagnetize the armature. The result includes a series of advantages, e.g. a smaller design, lower power consumption and possible use with multiple different switching units with different counterforces.
