Abstract:
1. A door position monitor system, comprising: a magnet; a magnetically conductive screw suitably adapted for securing a door latch to a door; a magnetically conductive set screw; a magnetically actuated switch; a nonmagnetic tubular housing unit suitably adapted to being mounted into the edge of a door at door latch mounting screw location for mounting said magnetically actuated switch into a door wherein said nonmagnetic tubular housing unit is further suitably adapted to align said magnetically conductive screw, said magnetically conductive set screw, and said magnetically actuated switch with said magnet to create a path for the magnetic force generated from said magnet to activate said magnetically actuated switch and said nonmagnetic tubular housing unit comprises external threads for mounting said nonmagnetic tubular housing unit into the edge of the door at door latch mounting screw location, internal threads to accept said magnetically conductive set screw and said magnetically conductive screw, and means to receive said magnetically actuated switch in the rear end of said nonmagnetic tubular housing unit; means for transmitting information, including information comprising the presence or absence of a magnetic field of said magnet mounted in a door frame, from said magnetically actuated switch to a sensor or signaling device; and means for protecting said magnetically actuated switch.
