Proposed is a magnetically passive position sensor (1) comprising a movable magnet, a plurality of contact spring elements (4) arranged in a motion region of the magnet and a resistance device (2). The contact spring elements (4) are spaced opposite the resistance device (2) and can be moved by the magnet to the resistance device (2). The resistance device (2) comprises a plurality of electrical contact surfaces (3) arranged opposite the contact spring elements (4) and arranged separately from each other. Each contact surface (3) is, for example, designed in a U-shape, comprising two limbs (11, 13) made of electrically conductive material, a gap (15) arranged between the limbs (11, 13) without electrically conductive material and a base region (17) made of electrically conductive material, said base region joining the limbs (11, 13). Owing to the U-shaped design of the contact surfaces (3), a potentially expensive electrically conductive material can be saved. In addition, dirt particles can preferably accumulate in the gap (15), where same scarcely affect the function of the position sensor. |
