  • Patent number: 9664536
    Abstract: A calibration system having an actuator with a rotatable shaft and a switch box housing a proximity switch and a calibration mechanism. The calibration mechanism is coupled to the shaft and includes a base, a target carrier, a driver, and an actuating button having a cam. The base includes a locating magnet, and the target carrier includes a primary magnet and a bias magnet polarized in the same direction as the locating magnet. The driver is shiftable between a first position in which the driver engages the target carrier and a second position disengaged from the target carrier. The cam engages the driver and shifts the driver between the first and second positions. Upon rotation of the shaft, the bias magnet automatically moves to a position aligned with the locating magnet when the driver is in the second position.

  • Patent number: 8872607
    Abstract: A method and apparatus for controlling operation of a safety switch assembly having a number of fixed and movable contacts, a control mechanism that alters the conducting state of the contacts, and a magnetizable member that extends between alternate portions of the safety switch assembly. The safety switch assembly includes a magnetically operable electrical switch that is positioned proximate the magnetizable material such that changes in the magnetic condition of the magnetizable material alter the conducting state of the magnetically operable electrical switch.

  • Patent number: 8866571
    Abstract: An enclosed proximity switch assembly includes a top enclosure and a bottom enclosure that are coupled to form an interior volume. A shaft protrusion upwardly extends from a top surface of the top enclosure, and an interior bore portion having an enclosed volume is defined within the shaft protrusion to form a portion of the interior volume. A first end of a vertical shaft is rotatably disposed within the interior bore portion such that the shaft rotates relative to the top and bottom enclosures. A samarium cobalt target magnet is coupled to the shaft, and the target magnet interacts with a samarium cobalt driver magnet within a proximity switch when the target magnet is rotated within a predetermined distance of a top portion of the proximity switch. The interaction causes a switch to move from a first state to a second state, or vice versa.

  • Patent number: 8866570
    Abstract: A reed switch apparatus utilizes one or more reed switches to communicate with one or more devices. In one configuration, the reed switch apparatus utilizes a single magnetic field to simultaneously activate two or more reed switches. In another configuration, two or more reed switches, each acting independent of one another are simultaneously activated by a single magnetic field. Additionally, a method of controlling at least two devices includes exposing a reed switch apparatus to a single magnetic field. Yet another method includes activating a device via the use of a single reed switch mounted to a portion of a warehouse structure.

  • Patent number: 8854163
    Abstract: The invention relates to an operating element (10) for a regulating and/or switching functionality having at least two switching or regulating stages, comprising: an actuating part (4) which can be actuated manually and thereby moved out of a rest position; at least three permanent magnets (1, 2, 3), comprising: a first movable permanent magnet (1), which is driven synchronously in its range of movement by the actuating part (4); a second movable permanent magnet (2), which, in a first partial range of the range of movement of the first permanent magnet (1), is synchronously entrained by it through magnetic force, and whose further movement is inhibited in at least one second partial range of the range of movement of the first permanent magnet (1) by at least one stop (5a); a third permanent magnet (3), which is stationary relative to the actuating part (4), for generating a magnetic return force on the at least first permanent magnet (1).

  • Patent number: 8847715
    Abstract: A permanent magnet is pivotally mounted in a top spacer layer of a switching device and rests on a flex arm created in an underlying flex circuit layer. The underside of the flex arm rests on a thin bar formed in a lower spacer layer beneath which lies a base layer including an electromagnet. Activation of the electromagnet causes rotation of the flex arm to thereby close and open electrical contacts formed respectively on the underside of the flex arm and on the top surface of the base layer.

  • Patent number: 8797130
    Abstract: The magnetic switch assembly of an embodiment generally comprises a switch housing coupled to and/or adjacent to a magnet housing. The switch housing may be coupled to, for example, a door frame, a window frame, or other substantially fixed location. The magnet housing including at least one magnet may be coupled to, for example, a door or other substantially mobile location adjacent to the switch housing. The proximity to or distance from the magnets in the magnet housing may actuate one or more reed switches within the switch housing to open and/or close a circuit and/or otherwise generate a signal that may be communicated to, for example, a security system to detect whether the door is open or closed.
