- a. a hand held programming unit having a data input mechanism, a radio transmitter and a radio receiver;
b. a magnet associated with said hand held unit;
c. a battery powered controller unit having a magnetically operable switch electrically connected to a radio receiver, said switch enabling said receiver when said magnet is brought into the conductive proximity of said switch; and
d. circuitry in said controller unit for controlling the at least one remote switch comprising (1) a first DC power source, at least one DC charge storage means, a first switchable connection between said first power source and said DC charge storage means, and a second switchable connection between said DC charge storage means and said at least one remote switch; and

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 the use of a simple magnet to signal the controller to initiate a default operation, such as brief serial operation of each switch. Programming and manual activation can thereby be accomplished by means of a radio control without sacrificing battery power.
