Abstract
In a magnetically passive position sensor, a mechanical axis (11) and a magnetic axis (12) of a magnet (2) point toward the same contact spring element from two or more contact spring elements (5, 6). This results, in particular, in the end regions of the position sensor achieving a particularly high accuracy. The magnet (2) has a guide polygon (8) which is used to hold the magnet (2) in a holder (10) such that it cannot rotate.
Claims5
A magnetically passive position sensor having a magnet arranged on a pivoting arm and having a large number of contact spring elements arranged in the pivoting range of the magnet, the contact spring elements lying opposite a thick film mesh, and it being possible for the contact spring elements to be moved by the magnet toward the thick film mesh, characterized in that the magnet (2) is held such that it cannot rotate about its mechanical axis (11), which points toward the thick film mesh (4), and is arranged with its magnetic axis (12) pointing in an intended direction.
A method for manufacturing a magnetically passive position sensor in which a magnet is arranged such that it can pivot over contact spring elements lying opposite a thick film mesh, characterized in that a magnetic axis of the magnet is determined, and in that the magnetic axis of the magnet is aligned with that contact spring element which is the least remote.
