You don't need to rewire your house in order to install a three-way switch system. The Wireless 3-Way Decora Switch Kit adds a second, remote control to a wall switch that powers an incandescent light up to 300 watts. The Wall Switch operates on 4 AAA batteries (sold separately).Replace your existing wall switch with this Wireless 3-Way Decora Switch Kit's Decora base switch. You'll be able to mount the included Decora wireless switch anywhere you want up to 50 feet away from the original switch for both local control from the base's built-in Decora switch and convenient remote control from the wireless wall switch, which sends a radio-frequency signal to the base to turn the light on and off. The included antenna wire increases the range of the receiver. The Wireless 3-Way Decora Switch Kit is designed for single-pole switches only. Since it incorporates a selectable A/B code switch, you'll be able to install more than one set of these 3-way kits within the 50-foot operating range. This switch set is not X10 compatible. The Wireless 3-Way Decora Switch Kit is also available in white.
