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.
