These smart Wi-Fi switches work with a choice of Touch, App- or Voice-Control with Amazon Alexa. They replace the traditional light switch with a smooth, ultra-thin toughened-glass front, leading-edge dimming technology and a stunning LED indicator to bring your home or office up to date. The screwless fronts are easy to install and fit a 35mm back box using standard wiring with no neutral required. The backlit LED indicators glow soft blue when off and bright blue when on, for locating your switches in the dark. Available in 4 colours and can be linked to  1-3 lights.
