    摘要: A contactless switching device has a permanent magnet which is rotatably mounted so that it is movable relative to a magnetic field dependent resistance which is located between the return poles of a return yoke. The permanent magnet is rotatably mounted in the manner of a rotatably mounted coil between the return poles of the return yoke and is magnetized in a diameter of the circle of rotation. Rotation of the permanent magnet varies the component of the magnetic field effective via the return poles between a maximum and substantially zero.
