摘要： A system that senses proximity includes a magnet producing a magnetic field and a sensor having a switch. The switch includes a cantilever supported by a supporting structure. The cantilever has a magnetic material and a longitudinal axis. The magnetic material makes the cantilever sensitive to the magnetic field, such that the cantilever is configured to move between first and second states. The switch also includes contacts supported by the support structure. The switch can be configured as a reed switch. When the magnet moves relative to the sensor, the cantilever interacts with a respective one of the contacts based on the position of the magnet during movement. The sensor can have multiple functionalities, such as it can: (1) be used to detect distance to an object, (2) be used to detect direction of a moving object, (3) include a memory that stores a last location of an object; (4) detect ferromagnetic-based materials and hard or soft magnetic objects; (5) be used to detect velocity and/or acceleration of an object and/or (6) be modified to include any function desired by a user.

摘要： Micro magnetic position sensor apparatus includes a magnet for producing a magnetic field, a fixed contact, and a cantilever having magnetic material positioned therein 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. The cantilever is mounted to provide it with a first position in electrical connection with the fixed contact and a second position in electrical disconnect with the fixed contact. The cantilever is further mounted so as to be normally in one of the first and second positions and movable to the other of the first and second positions when the magnetic field lines in the magnetic field are altered relative to the cantilever by proximity of an external object.

摘要： A latching relay employing a movable cantilever with a first permanent magnet and a nearby second magnet is disclosed. The permanent magnet affixed to the cantilever is permanently magnetized along its long (horizontal) axis. The cantilever has a first end associated to the first pole (e.g., north pole) of the first magnet, and a second end associated to the second pole (e.g., south pole) of the first magnet. When the first end of the cantilever approaches the second magnet, the first pole of the first magnet induces a local opposite pole (e.g., south pole) in the second magnet and causes the first end of the cantilever to be attracted to the local opposite pole of the second magnet, closing an electrical conduction path (closed state). An open state on the first end of cantilever 10 can be maintained either by the second pole of first magnet being attracted to a local opposite pole in the second magnet or by a mechanical restoring force of flexure spring which supports the cantilever. A magnetic generator provides a third magnetic field about the first magnet and produces a torque on the associated cantilever to force the cantilever to switch in one of the closed, neutral and open states.

A third electromagnet (e.g., a coil or solenoid), when energized, provides a third perpendicular magnetic field about the first magnet and produces a torque on the associated cantilever to force the cantilever to switch between closed and open states. A few alternate embodiments of the relay are also disclosed which include a case where the latching feature is disabled, and another case where an external magnet is used to switch the cantilever.
