Position detecting device for switching device of motor car for detecting position of shift lever, has magnetic field influence device influencing magnetic field of magnetic field generation device in magnetic field portion

摘要

The device has a magnetic field generation device (2) producing a magnetic field and characteristic of a magnetic field seizing detector e.g. magnetic field sensor and hall sensor. A magnetic field influence device (4) influences the magnetic field of the magnetic field generation device in a magnetic field portion. The magnetic field generation device comprises a magnet i.e. permanent magnet, and the magnetic field influence device comprises a flux guide plate and the magnet e.g. permanent magnet.
