<p>Position sensor 1 generates an electric signal according to the position of a movable element (e.g. a vehicle clutch pedal, steering arrangement or throttle). It comprises: first sensor element 2 with a (e.g. linear, arc-shaped or elliptical) resistive track 5 (and optionally conducting track 4) formed on substrate 3; and second sensor element with slider finger 8 which forms a sliding contact 9 with the track so as to transmit the position of the movable element. The first sensor element comprises functional and dead areas 10, 11, the sliding track being laid in the functional area only; and a filling structure 19 which bridges a difference in level between the track and the substrate (e.g. a metal, plastic or ceramic ramp (14. Fig. 2) in transitional area 15 or a bridge across the entire dead area (19, Figs. 3 and 4)).</p> |
