Patent ID: 8022796

Claim:
A contactless switch comprising a) an angularly and/or axially adjustable rotor with a key retention device at a first axial end of the rotor, wherein the rotor is rotatable around a rotational axis, b) at least two magnetic field sensors, c) at least one main magnet which is rotatable around an auxiliary axis, wherein the at least one main magnet is arranged so that a magnetic field of the at least one main magnet influences the at least two magnetic field sensors, and wherein, due to the influencing by the magnetic field, the magnetic field sensors are adapted to issue signals which correlate with a magnetic field strength of the magnetic field and/or a change of the magnetic field strength and/or a polarization of the magnetic field, d) an infrared transceiver arranged centered on the rotational axis and adjacent to a second axial end of the rotor opposite the first axial end, and e) a connecting element comprising at least one gear and/or at least one auxiliary magnet between the rotor and the main magnet, wherein the contactless switch is adapted to displace the main magnet by the rotor via the connecting element.
