Abstract

Control signals are provided by means of a magnet, a sensor sensitive to magnets, and elements influencing the magnetic field and having a relative movement. A magnetoresistive circuit is placed between one stationary and at least two simultaneously linear or circular movable magnetic flux concentrators having an U- or V-shaped arrangement and being alternately effective in the magnetic circuit. The magnetoresistive circuit is operated in its saturation range, if at least one of the magnetic flux concentrators is effective.
