Create a 3-way, 4-way, or more-way switch by combining the X10 Companion Switch for WS4777 with an X10 Master Switch (WS4777). This companion switch sends commands to the master switch, which then relays commands to the appropriate X10 receiver. It's perfect for hallways, stairways, and other areas where two switches for one X10 receiver would be convenient.
