Locator (position sensor, position encoder), in particular for the selector lever of a vehicle gear (transmission, gearbox)

The invention relates to a locator for the selector lever of a vehicle gear, which is intended to sense the gear mode selected. According to the invention, the locator is a film pressure sensor consisting of two interlaminated polymer layers. One layer is coated with a semiconductor material and the...

Zusammenfassung:	The invention relates to a locator for the selector lever of a vehicle gear, which is intended to sense the gear mode selected. According to the invention, the locator is a film pressure sensor consisting of two interlaminated polymer layers. One layer is coated with a semiconductor material and the other with comb-like, interdigitised electrodes which branch off, on the one hand, from a conductor track and, on the other hand, from a resistance track. These pressure-sensitive regions are locally confined to the defined positions of the selector lever, the position of which is transmitted to the film pressure sensor by means of a slider.
