Abstract
A battery powered radio programmable remote switch controller and a separate hand held programming unit (programmer) designed to conserve the life of the life of the controller batteries using a combination of low voltage circuitry in the controller and a magnetic switch in the controller that is triggered by the programmer. When brought into proximity with the controller, a magnet in the programmer activates a magnetic switch in the controller which energizes a radio receiver in the controller to receive programming transmitted by the programmer. After downloading the program, removal of the programmer from the proximity of the controller deactivates the magnetic switch turning off the radio receiver, thereby saving over 99% of the power otherwise required to continuously monitor for a radio signal. Controller power is further conserved by holding its remote switch energizing capacitor(s) in an uncharged state until just prior to activation, saving the energy lost by capacitive leakage and by using separate low and high voltage batteries to power the electronics and the remote switches respectively. Magnetic activation also allows for manual operation of the remote switch(es) by t…
