摘要:
An improved magnetic switch assembly (16) has a housing (24), a first electrode (40) positioned within the housing (24), a second electrode (42), and a magnetically movable component (48) located within the housing (24) and shiftable between a first position in simultaneous contact with electrodes (40, 42), and a second position out of such simultaneous contact. The electrode (40) has a radially enlarged contact section (44, 58) adjacent the free end thereof which prevents hangup or sticking of component (48) in the first position.

An improved, low-cost magnetic switch assembly (16, 16a) is provided having an easily fabricated housing (24, 24a) and cover (29, 29a) formed of non-conducting synthetic resin material. A pair of electrically conductive switch elements (30, 32, 30a, 32a) are positioned in spaced relationship with the housing (24, 24a) along with a body (40, 40a) shiftable between a first position in simultaneous contact with the switch elements (30, 32, 30a, 32a), and a second position out of such simultaneous contact. The housing (24, 24a) is also equipped with a first attractive component (38, 38a) which magnetically reacts with the body (40, 40a) to hold the latter in one of the positions thereof when the assembly (16, 16a) experiences a first magnetic field condition, but allows the body (40, 40a) to move to the other of the positions thereof when a second magnetic field condition is experienced adjacent the assembly (16, 16a).

A lock having a sensor, the lock comprising a housing defining a chamber with a longitudinal axis. A latch mechanism is located within the chamber of the housing and is movable relative thereto in a direction transverse to the longitudinal axis between a retracted position wherein the latch mechanism is substantially within the housing, and an extended position wherein the latch mechanism extends at least partially outside of the housing. The latch mechanism at least partially comprises a ferrous material. A first switch mechanism fixed within the chamber, the latch mechanism ferrous material causing the first switch mechanism to activate in one transverse position of the latch mechanism and the first switch mechanism deactivated in another transverse position of the latch mechanism.

A device for setting up a contact connection between independent electrical circuits, which comprises a plate made of magnetic material 1 on which is placed a sheet 2 of insulating material, supporting at least two independent conductor circuits 3, 4 adapted to be connected together by means of a magnetized conductive member 6, held in position by the attraction of the said magnetic plate 1.The invention relates to a device used in games and in the audio-visual field.
摘要:
A security switch for detecting an actuator comprises a magnetic field source, a magnetically susceptible object, and a circuit. The magnetic field source is configured to produce a magnetic field gradient. The magnetically susceptible object is suspended at a first position at least in part due to the magnetic field gradient and shiftable to a second position when the actuator affects the magnetic field gradient. The circuit is configured to detect when the object is in the second position.
摘要:
A magnetic tether switch for equipment or vehicles is described. The magnetic tether switch may include a base having a first magnetic assembly. The first magnetic assembly may include a magnet and a first magnetic flux return component, or multiple magnets with reversed polarization directions. The magnetic tether switch may include a cap including a second magnetic assembly. The second magnetic assembly may include a magnet and a magnetic flux return component, or multiple magnets with reversed polarization directions. Alternatively, the second magnetic assembly may be composed of a ferrous material. The base may include a circuit with multiple contacts, where attaching the cap to the base may connect or disconnect the contacts to each other by moving the magnet within the base by magnetic attraction from the cap.
