Abstract
Remote control of a slave electric circuit is produced by sensing change in state of power flow through a master electric circuit and transmitting a resultant wireless signal between apparatus included in each the master circuit and the slave circuit. In a representative embodiment, the master electric circuit might include a main lamp which can be switched on and off while the remote electric circuit may include a supplementary lamp which is to be controlled. A fundamental implementation is that of producing a distinctive electromagnetic wireless signal at the master circuit apparatus in immediate response to the sensed change in the state of power flow through the master electric circuit whereupon the signal may be transmitted to and remotely received by the slave electric circuit control apparatus and utilized to correspondingly change the immediate state of power flow through the slave circuit with the subsequent result that the slave electric circuit may remotely turn-on when the master electric circuit is locally turned-on and conversely the slave electric circuit may remotely turn-off when the master electric circuit is locally turned-off.
