Abstract

A magnetic passive position sensor including a base plate and a cover which form a housing, a magnet that can be moved outside the housing, a resistance network that has several individual electric contacts, and a plurality of contact spring elements that are arranged within the range of motion of the magnet, are interconnected by a common base, and consist of a bending zone and a contact zone. The contact spring elements face the contacts of the resistance network in such a way that the contact zones can be moved from the magnets against the contacts of the resistance network, the contact zones of at least two contact spring elements being assigned to each individual contact of the resistance network. Two adjoining contact spring elements are mechanically interconnected.
