A circuit was required that would detect when current was drawn by a varying AC load and once this current was detected, switch on the load's AC line voltage to other circuitry. The circuit would also need to meet the following requirements: 1) draw zero current until the varying AC load was activated, 2) have Universal AC voltage compatibility (90 to 264 VAC), and 3) be low in parts count and compact in size.
