Abstract: The contactless proximity switch detects one or more predefined spacing distances between a first part and a second part. The two parts are movably disposed relative to one another. A magnetic angle sensor is disposed in or on the first part and a driver magnet with a driving magnetic field is arranged in or on the second part. When the two parts are at the predefined spacing between then the driving magnetic field produces in the angle sensor an effective direction of field lines which differs from the direction of the original state field lines of the angle sensor. The original field direction is imposed on the angle sensor by a biasing magnetic field which originates either from the driver magnet or from a separate biasing magnet.
