PROBLEM TO BE SOLVED: To improve flexibility of a flat piece under the same geometric arrangement of at least one flat piece being as it is without changing a total space condition of a micro switch. This is to be done without changing a maximum power obtained at an end part of the flat piece. SOLUTION: A magnetic microswitch includes two flat pieces 1, 2 each including end parts 5, 5' that form a clearance (e) at their overlapped parts, and at least one flat piece of two flat pieces made of a magnetic material has one end 3 attached to the base member through a leg part 9, a middle part 4, and the end part 5 with length L 0. The flat piece 1 has flexibility against the other flat piece 2. A cross section of the middle part 4 of the flexible flat piece 1 has small flexural resistance by forming to be smaller than the end part 5. Therefore, the flat pieces can be bent at least to the same distance as the clearance (e) to be contacted under an influence of magnetic field as well as they have an enough returning power to the opening position without magnetic field.

47 Electromechanical Latching Relay and Method of Operating Same US12268936 2008-11-11 US20090066449A1 2009-03-12 Jun Shen
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 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.

A micromechanical switch and a method for operating the micromechanical switch between an open position and a closed position by moving a magnet between two positions. The magnet produces a magnetic flux that travels through a magnetically conductive layer. The magnetic flux within the magnetically conductive layer forcibly draws a contact element into contact with an electrically conductive layer and electrically shorts the open electrical contacts.

A micromechanical switch and a method for operating the micromechanical switch between an open position and a closed position by moving a magnet between two positions. The magnet produces a magnetic flux that travels through one of two different conductive layers. The magnetic flux within the conductive layer forcibly draws a contact element into contact with the conductive layer and electrically shorts the conductive layer. Depending upon which conductive layer is shorted, the micromechanical switch is set in either the open position or the closed position.
