Abstract

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) and having flux concentration, structure associated therewith.
