The Retrotouch Touch & Remote light switch can be touch or remote controlled, and come with a handy 2-way remote control unit that works through walls for seamless lighting control. These remote controlled light switches are a retrofit solution, which use existing wiring and are quick and easy to install. They are less expensive than other home automation remote light switch products developed for installation primarily in new-builds. The Touch & Remote control light switch collection includes a wireless remote light switch for difficult-to-reach places and LED compatible light switches. Please note, the 2 way touch switches are only compatible with other touch switches. You're unable to control touch switches on one circuit if linked with a standard rocker switch.
