This switch is 3 gang 2 way - meaning the switch can control three sets of lights whilst working with another RetroTouch RTS2020 or RTS2040 2 way light switch. Please note this 2 way switch will not work when paired with a mechanical or non RetroTouch 2 way switch - it must be used with another RTS2020 or RTS2040 2 way switch. Each gang can control up to 580 watts (simply add the wattage together for all the bulbs being controlled by each gang). The stunning Retrotouch RTS2020 Touch and Remote light switches can be touch or remote controlled, and come with a remote control unit that can control up to 3 gangs and can work through walls for seamless lighting control. The Retrotouch RTS2020 Touch and Remote light switches have a glass surround with chrome trim around an LCD touch screen and come in 1 gang and 3 gang options so enabling you to control from 1 to 3 independent lights from one unit. The light switches can, if needed, be controlled by an optional master remote control. This gives the user the power to turn on/off any light switch in the home, or set scenes - patterns of light - in different rooms, without the need for expensive controllers or senders. All models in the Touch and Remote full glass range measure 86mm x 86mm and come with a 1 year warranty. Retrotouch products give the user the power to control their lighting the way they want, using the advanced features or simple controls. This switch can be a straight swap for your old switch and uses the existing wiring. Suitable for LED bulbs but a minimum load of 5w is required.
