Abstract:
Micro magnetic position sensor apparatus comprising:a magnet generating a magnetic field with magnetic field lines; a mounting substrate; a first fixed contact mounted on the substrate; a cantilever including magnetic material positioned in the cantilever to produce a torque on the cantilever in the magnetic field, the torque tending to align the cantilever with magnetic field lines in the magnetic field; and the cantilever being mounted on the substrate so as to provide the cantilever with a first position in electrical connection with the fixed contact and a second position in electrical disconnect with the fixed contact, the cantilever further being mounted so as to be normally in one of the first and second positions and movable to an other of the first and second positions when the magnetic field lines in the magnetic field are altered relative to the cantilever to produce the torque on the cantilever tending to move the cantilever to the other of the first and second positions.
