Abstract
A position sensor includes a first part having several electrically conductive elements, a second part having an electrical conductor, and holding device holding the first part and the second part together with the conductive elements and the conductor being spaced apart and permitting relative movement between the conductive elements and the conductor. Included is a signal generator for generating and supplying different electrical signals to one of the first part and the second part for reception in a contactless manner by the other of the first part and the second part with a magnitude that is dependent upon the relative position between the conductive elements and the conductor. There is also a signal detector connected to the other of the first part and the second part for differentiating the electrical signals received thereby to determine the relative position between the conductive elements and the conductor.
