ABSTRACT:
An arrangement for producing electrical signals by way of semiconductor elements which are dependent upon a magnetic field employs at least two field plates which are arranged adjacent to each other on at least one pole of a magnet. An iron part can be moved over the field plates whose width is selected in such a way and which is guided with respect to the field plates in such a way that when the iron part completely covers one field plate the other plate is not covered. The field plates are magnetic field dependent two pole elements having an electrical resistance characteristic which changes as a function of an applied magnetic field so that electrical signals are generated in response to field change when the field plates are connected in an electrical circuit.
