| 摘要 |
The invention relates to a magnetic passive position sensor, comprising a substrate (1) with a resistance network (2) which is arranged on this substrate (19) and is assigned a contact spring structure (8), which can be deflected under the action of a permanent magnet (11), with electrical connection between the resistance network (2) and the contact spring structure (8) being established by contact which is dependent on the position of the permanent magnet (11), the contact spring structure (8) and the resistance structure (2) being enclosed in a sealed housing (1, 12) and the permanent magnet (11) being movable outside the sealed housing (1, 12). In the case of a position sensor with improved magnetic force of the permanent magnet (11), the permanent magnet (11) is polarized in the direction of movement of the contact spring structure (8), a flux guiding device (14, 15a; 15b) for increasing the concentration of the force of attraction of the undisturbed magnetic field being arranged near the permanent magnet (11).
