Abstract
A two-terminal line-powered control circuit is disclosed in which a triac is used to switch AC power to a load. When the triac is not conducting, a portion of the voltage appearing across it is rectified and filtered and used to supply power to a radio control circuit. When the triac is conducting, the voltage appearing across inverse-parallel connected diodes, which are in series with the triac, is stepped-up using a transformer, then rectified and filtered and used to supply power to the radio control circuit. The radio control circuit is in turn used to control the operation of the triac in response to a remotely transmitted radio signal.
