Abstract
A smart switch for control of a lighting load from an AC voltage source can replace any switch in a three-way lighting control system. The smart switch can be connected on the line-side or the load-side of a three-way system with a standard three-way switch in the other location. The switch includes two semiconductor switches to control the connected lighting load. The switch preferably includes two sensing circuits for detecting the voltages at two of the load terminals of the switch to determine the state of the connected three-way switch(s), and thus, the load.
