Abstract
A switch which can be activated by a magnetic force and which includes a housing having at least two spaced apart electrical terminals thereon. Internal of the housing is contained a coil spring supported at one end thereof, and axially holding an elongated, magnetically responsive, conductive member in cantilevered fashion within the housing. The elongated member and spring can move from an aligned position to a deflected position responsive to the magnetic force. A first contact interconnects one of the electrical terminals with the supported end of the elongated member, by means of the coil spring. A second contact is interconnected to the other of the electrical terminals and contacts the cantilevered end of the elongated member in one of its two positions.
Claims17
A switch activated by a magnetic force comprising:
- a housing;
- at least two spaced apart electrical terminals;
- on said housing;
- an electrically conductive coil spring supported at one end thereof within said housing;
- an elongated, magnetically responsive, conductive member axially supported by said spring in a cantilevered fashion within said housing, said elongated member and said spring being adapted to move from aligned to deflected positions responsive to a magnetic force;
- first contact means interconnecting the supported end of said spring with one of said terminals, and second contact means interconnected to the other of said terminals encircling said conductive member and contacting said conductive member in one of said aligned and deflected positions.
A switch activated by a magnetic force, comprising:
- a housing;
- at least two spaced apart electrical terminals on said housing;
- an electrically conductive coil spring supported at one end thereof within said housing;
- an elongated, magnetically responsive, conductive member axially supported by said spring in a cantilevered fashion within said housing, said elongated member and said spring being adapted to move from aligned to deflected positions responsive to a magnetic force;
- first contact means interconnecting the supported end of said spring with one of said terminals, and second contact means interconnected to the other of said terminals encircling said conductive member and contacting said conductive member in one of said positions, and wherein said first contact means comprises a U-shaped member, one leg of which is connected to said one terminal and the base of which contacts and supports one end of said spring.
A burglar alarm, comprising:
- a source of energy;
- an alarm means;
- and a magnetic switch interconnecting said source and said alarm means, wherein said magnetic switch further comprises;
- a housing;
- at least two spaced apart electrical terminals on said housing;
- a coil spring supported at one end thereof within said housing;
- an elongated, magnetically responsive, conductive member axially supported by said spring in a cantilevered fashion within said housing, said elongated member and coil spring being adapted to move from an aligned position to a deflected position responsive to a magnetic force;
- a first contact means interconnectig the supported end of said elongated member with one of said terminals, and second contact means interconnected to the other of said terminals encircling said conductive member and contacting the cantilevered end of said elongated member in one of said positions.
