Essential Info

These easy-to-install three-way wall switches offer you a simple solution for automating any wired-in light fixture currently controlled by two or more switches. You can control lights directly from the switch or remotely from any X10 -compatible transmitter. The switch also responds to the ALL LIGHTS ON/OFF command, and you can dim the light from any X10 transmitter with DIM/BRIGHT control.


What's Included

  • 1x - Three-Way X10 Master and Slave Switch Set - White
  • More Info

    Just like the standard X10 wall switch, you can use the three-way wall switch with the Mini Timer, Clock Radio Timer or Home Automation interface for automatic timed lighting control. You can also control lights from anywhere in the world with a single phone call using the X10 Telephone Transponder.

    Important ordering information: When two switches control the same light, it's called a three-way circuit. A three-switch system is a four-way circuit, etc. Each three-way circuit requires one master switch and one slave switch. For circuits with more than two switches, simply add additional slave switches for each additional switch. 500 watts. Wall plate not included.

    Order your X10 Three-Way Wall Switches and discover how easy automating three-way lights can be.

    Please note that the X10-compatible dimmer switch can be used only with incandescent lights.

    JOHN -- hampton, NH   4/8/2010
    Works great. Easy installation.
    DAVID -- landenberg, PA   3/15/2010
    I've purchased and installed X10 switches in the past for my customers and they work just fine. From my perspective and easy installation for nearly anyone - you do NOT need to be an electrician like me. Instructions are simple to follow. These were a replacement for the newer versions that smarthome offers (ToggleLinc Relay - INSTEON Remote Control On/Off Switch (Non-Dimming), Ivory ) which I had to send back "2" times, both sets were NOT working even when wired on a system that we created on the customers kicthen table!! If you want a simple system and need a 3way application this is the only way to go in my humble opinion! Dave Bartlett - owner of Bartlett Electric

    ANDREW -- lakewood, CO   12/12/2009
    Had on of these installed previously and after a couple of years of functioning well, the switch went out. Love the switch hopefully the new one lasts longer
    THOMAS -- carlsbad, NM   11/28/2009
    I will need another 3 way switch since I blew up the first. I have an old house with old wiring and I connected the wrong set.
    JOHN -- oakland gardens, NY   11/21/2009
    works perfect
    RICHARD -- scotch plains, NJ   8/23/2009
    This switch brings the lights up slowly instead on on and off.
    WILLIAM -- sierra vista, AZ   3/8/2009

    ROBERT -- villa rica, GA   2/19/2009
