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.12-27-2012
20120286907MULTI-STAGE MAGNETIC SWITCH - A multi-stage magnetic switch includes a base and a rotary member rotatably held in the base. The base holds a latch member elastically extended outwards. The rotary member includes a plurality of latch notches. Each latch notch has a latch plane and an arched convex surface which have respectively one side extended to the outer surface of the rotary member. The latch member latches on the latch plane and is adjacent to the arched convex surface. The latch member is pressed and retracted through the latch plane when the rotary member rotates against the base so that the latch member latches on the latch notches sequentially to form multi-stage positioning. Moreover, greater force can be applied to retract the latch member pressed by the arched convex surface to reverse the rotary member. The switch of the invention thus formed has simple structure and makes multi-stage positioning easier.11-15-2012
20130021123Enclosed Proximity Switch Assembly - 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.01-24-2013
20080231400Low Current Switch for Motor Car Anti-Theft Lock - A switch for starting and stopping at least one operating unit of a motor vehicle configured to cooperate with an anti-theft lock having a stator and a rotor that can be rotated inside the stator and that has at least one permanent magnet secured to the rotor has at least two Reed bulbs provided with flexible leads and electrically linked by the leads to the contacts of a connector. Said Reed bulbs are arranged on a connector body designed to be fixed removably to said stator in a so-called operating position.09-25-2008
20130169388PROXIMITY SWITCH - Proximity switches are disclosed that preferably are provided in a hermetically sealed unit that can be used in harsh environments and under significant pressures, such as underwater and in nuclear power facilities, without having any parts that would require replacement or periodic maintenance. The proximity switches are preferably switches actuated by physical movement of a contact in response to changing magnetic forces. The switches are preferably disposed in a body tube optionally including a hermetic seal assembly to seal an open end of the body tube and/or a ferrule that prevents electrical wires attached to the switch inside the body tube from being pulled away from the switch. Further, the switches preferably maintain a contact pressure between electrical contacts sufficient to withstand acceleration seismic testing of 10 g with no contact discontinuity.07-04-2013

20080278269System and Method for an Information Handling System Articulated Magnetic Latch - A magnetic latching system selectively couples and releases an information handling system housing and lid by moving a magnet associated with one of the housing or lid relative to a ferrous metal in the other of the housing or lid to selectively apply magnetic attraction between the housing and lid. A latch retainer interfaced with the magnetic latching system retains the magnetic latch in a released position until the lid and housing approach a closed position and then allows the magnetic latch to return to a locked position, thus bringing the lid and housing to a securely closed configuration without slamming together due to the magnetic attraction between the magnet and ferrous metal.11-13-2008

An electrostatic comb drive pivots the rod between a first and second pivotal position in dependence upon the input signal for the comb drive. In its first position the magnetic material is positioned closely adjacent a magnetic flux sensor on the substrate so that flux flow through the rod flows through the sensor which then generates an output signal. Conversely, with the rod in its second position, the magnetic material is spaced from the sensor so that flux does not flow through the magnetic flux sensor.08-15-2013
