  • Patent number: 8174343
    Abstract: A relay comprises a movable body placed in a cavity which is formed on a substrate and surrounded by a spacer layer and sealed by a cover layer. The movable body comprises a first magnet which is permanently magnetized and has at least a first end. A nearby switching electromagnet, when energized, produces a switching magnetic field which is primarily perpendicular to the magnetization direction of the first magnet and exerts a magnetic torque on the first magnet to force the first magnet and said movable body to rotate and close an electrical conduction path at the first end. Changing the direction of the electrical current in the switching electromagnet changes the direction of the switching magnetic field and thus the direction of the magnetic torque on the first magnet, and causes the first magnet and said movable body to rotate in an opposite direction and opens the electrical conduction path at the first end.

  • Patent number: 8143978
    Abstract: An electromechanical relay employing a movable first magnet and a nearby switching electromagnet is disclosed. The movable first magnet is permanently magnetized with a magnetic moment and has at least a first end. The switching electromagnet, when energized, produces a switching magnetic field which is primarily perpendicular to the magnetization direction of the first movable magnet and exerts a magnetic torque on the first magnet to force the first magnet to rotate and closes an electrical conduction path at the first end. Changing the direction of the electrical current in the switching electromagnet changes the direction of the switching magnetic field and thus the direction of the magnetic torque on the first magnet, and causes the first magnet to rotate in an opposite direction and opens the electrical conduction path at the first end. Multiple magnetic layers can be arranged to form closed magnetic circuits to facilitate switching and maintaining switched states.

  • Patent number: 8134431
    Abstract: The invention relates to a switch, in particular a vehicle switch, comprising a switching part which can be coupled to an actuation element, is rotationally mounted about a rotational axis and can adopt defined switch positions. The switching part comprises at least one permanent magnet comprising several south pole and/or north pole sections, and at least two magnetic field sensors which are arranged in a fixed manner in relation to the switching part. The output signals of said sensors, according to the switch position of the contact piece, is dependent upon whether a south or north pole section of the at least one permanent magnet is in the detection range of the respective magnetic field sensor and said output signals form an easy to determine binary switch code in the respective switch position. The invention also relates to an evaluation device for said type of switch, a switch unit comprising said type of switch and an evaluation unit.
