Patent number: 8264308Abstract: A magnet is affixed to a shaft or other pivoting or rotating member of a switch mechanism, on the axis of rotation. The radial position of the resulting magnetic field is monitored. A change in the magnetic field radial position, optionally in excess of a threshold, indicates the onset of switch actuation, prior to operative actuation of the switch mechanism. The radial position of the magnetic field is sensed by a magnetic rotary encoder. The detection of switch actuation onset may be used to remove current from a circuit prior to operative switch actuation. Because the magnet is rigidly affixed to the shaft, there is no lost motion. Because the shaft position and encoder are magnetically coupled, the detection mechanism contains no moving parts and no mechanical linkage or coupling, and its performance does not degrade due to shock, thermal effects, vibration, or wear.Type: GrantFiled: September 4, 2008Date of Patent: September 11, 2012Assignee: Shallco, Inc.Inventor: Roderick M.

A magnet associated with one of the movable and static portions reacts with structure associated with the other of the movable and static portions so as to provide haptic feedback when the movable portion is moved with respect to the static portion.Type: GrantFiled: March 12, 2008Date of Patent: March 20, 2012Assignee: TouchSensor Technologies, LLCInventors: John North, Deron Stambaugh

Patent number: 8134431Abstract: 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.Type: GrantFiled: March 9, 2007Date of Patent: March 13, 2012Assignee: Valeo Schalter und Sensoren GmbHInventors: Reiner Mozer, Daniel Horst, Conny Hein

Patent number: 8134430Abstract: A trigger device includes a retaining frame, a swing arm, a toggle switch, a resilient member and a touch component. An end of the swing arm is connected to the middle of the retaining frame, and another end of the swing arm is connected to a magnetic sensor, and an end of the toggle switch is pivotally connected to the top of the retaining frame. The swing arm forms a pressing rod disposed on the toggle switch and pressed for swinging the swing arm. The retaining frame and swing arm are connected to the resilient member, and the touch component is mounted into the retaining frame and installed at another end of the toggle switch. An elastic button is installed between the touch component and the toggle switch for pressing the toggle switch. Obvious feel and tough can be provided to enhance the operability and convenience of the trigger device.Type: GrantFiled: November 14, 2006Date of Patent: March 13, 2012Assignee: Unitech Electronics Co., Ltd.Inventors: Chun-Hsien Chen, Tzu-Chi Wei

Patent number: 7994886Abstract: A contactless switch module, which is actuatable between a closed circuit position and an open circuit position, a plurality of magnetic field sensing sensors, and a plurality of magnets. The switch also includes a multi-channel switch controller. Each one of the plurality of magnetic field sensing sensors is communicatively coupled to an input channel of the multi-channel switch controller. The multi-channel switch controller is configured to determine a switch state based at least upon the respective states of its input channels.Type: GrantFiled: May 17, 2007Date of Patent: August 9, 2011Assignee: Korry Electronics Co.Inventor: Jeffrey Clark Bedell

Publication number: 20110128102Abstract: A magnetic switching device is provided with a first switching device which is provided with a movable magnet connected to a contact bridge, and with a second switching device which is provided with a magnet connected to a movable switch element. The magnets have the same polarity on the front faces facing each other. Positioned between the magnets is a separating plate made of ferromagnetic material, which is smaller than the front faces of the magnets which face each other.Type: ApplicationFiled: February 20, 2008Publication date: June 2, 2011Inventors: Klaus Pfeiffer, Ulrich Konzelmann

Patent number: 7948378Abstract: A non-defeatable magnetically actuatable switch device is shown and described for restricting access to industrial controls. The non-contact switch device employs one or more non-contact access switches, and an access key removably disposed in close proximity to each access switch. Removal or installation of an access key alters the electrical state of a corresponding access switch. A connected control unit determines a mode of operation, or grants permissions, based on the combination of access keys that are present or absent from the device. A lockable or sealable cover is provided over the access keys to limit unauthorized access. A tamper detection switch is also provided for the sole purpose of identifying foreign magnetic sources in the vicinity of the access switches to ensure that the device is non-defeatable.Type: GrantFiled: October 6, 2008Date of Patent: May 24, 2011Assignee: Toptech Systems, Inc.Inventors: Michael Magargee, Robert Denney, William Porthouse, Thornton Caraway
