Smart Switches

This category covers wall switches, in-wall relay modules, a 20 A switch for high-power circuits such as water heaters, and touchscreen panels that combine switching with scene control. What fits is decided at the wall: the number of gangs, whether the back box carries a neutral wire, and the box itself — the Light Switch H2 and Dimmer H2 sold here are the square EU System-55 models, and the MagicPad S1+ mounts on a single 86 × 86 box. Where the existing switch plate has to stay, an in-wall module behind it does the same job without changing the look of the room.
