ABSTRACT:
A passive magnetic position sensor, has a substrate with a resistance network arranged on it, and a contact structure which is associated with the resistance network and which can be deflected under the action of a magnet device. An electric connection which is dependent on the position of the magnet device is produced between resistance network and contact structure. In order to provide a position sensor which has a high resolution, operates with a little wear, and is constructively simple to produce, the contact structure is developed as contact-spring structure, and the junction points of the resistance network are connected to contact surfaces also applied on the substrate. The contact-spring structure is arranged at a constant distance from the contact surfaces, the latter entering into contact with the contact-spring structure under the action of the magnet device. At least the contact-surfaces and the contact-spring structure are enclosed in a tight housing, and the magnet device is movable outside the tight housing. A stepped output signal is tapped off from the contact structure as a function of the position of the magnet device.
