Patent ID: 7015688

Claim:
A device for adjusting rotation angles and capable of functioning as a switch comprising a stator, which has a receptacle which is open on one side and is approximately in the form of a pot, a rotor which is mounted on the stator, which is mounted on a holder with an open side of the stator receptacle facing the holder such that the rotor rotates in the stator receptacle as a rotary bearing between at least two rotation angle positions, a magnet, which moves by means of the rotor, and a magnetic field sensor produces a signal in association with the magnet which signal corresponds to the rotation angle position, wherein 1) the magnetic field sensor is arranged in the stator receptacle on the stator and/or is on a part which is mounted in the stator, such that the stator acts as a mount for the magnetic field sensor, 2) the magnet is arranged on the rotation axis of the rotor, 3) the magnetic field sensor is a Hall sensor, which is two-dimensionally sensitive for magnetic fields parallel to its chip surface, and is mounted on the side of the stator receptacle, which faces away from the open side, and 4) the holder is a printed circuit board.
