Dimmer switch for use with lighting circuits having three-way switches

摘要: A smart dimmer switch for control of a lighting load from an AC voltage source can replace any in three-way or four-way system. The be connected on the line-side load-side system with standard other location. Further, and is operable to coupled two switches. includes either one semiconductor switches intensity load. preferably sensing circuit detecting electrical characteristic (i.e., current) at terminal determine state switch(s) switch. controls response toggle actuation button
