Abstract

Es sind schon magnetische Positionssensoren bekannt, mit einer auf einem Träger ausgebildeten Widerstandsbahn, einer zur Widerstandsbahn beabstandeten Leiterbahn, einem beweglich gelagerten Kontaktmittel zur Herstellung einer lokalen elektrischen Verbindung zwischen der Widerstandsbahn und der Leiterbahn. Das Kontaktmittel ist ein Magnet, der einzelne Segmente der Leiterbahn an die Widerstandsbahn anzieht und auf diese Weise den Kontakt zur Widerstandsbahn schließt. Nachteilig ist, dass die Herstellungskosten für den Positionssensor vergleichsweise hoch sind. Bei dem erfindungsgemäßen Positionssensor werden die Herstellungskosten verringert. Erfindungsgemäß ist vorgesehen, dass die Leiterbahn (5) auf einer elastischen Folie (12) ausgebildet ist, dass das Kontaktmittel (6) auf der elastischen Folie (12) entlang der Leiterbahn (5) beweglich gelagert ist und derart gravimetrisch auf die Leiterbahn (5) wirkt, dass ein lokaler Kontakt mit der Widerstandsbahn (2) entsteht.
