Wireless stick-on switches: a switch where you want one, without a wall chase
A switch that runs on a battery, talks to the light directly, and mounts with adhesive. It removes the single most expensive part of adding a light switch to a finished room: the wall.
What it takes out of the job
Adding a conventional switch to a room that is already decorated is not a switch problem, it is a building problem. Chase the wall, run conduit, pull the cable, make good the plaster, repaint the wall — and on a solid wall in a finished house that is a day's work, a mess, and a decorating bill that dwarfs the switch itself. On a partition or near a structural element it may not be allowed at all.
A stick-on switch replaces all of that with peeling a liner and pressing it to the wall. Ten minutes, no dust, no reinstatement, nothing to repaint. In rented accommodation, where cutting a wall is not an option at any price, it is the difference between having a switch there and not.
The position stops being decided by the cable
This is the part people underestimate until they have lived with it. A wired switch goes where the electrician could reach when the house was built. A wireless one goes where the person actually reaches for it.
- One on each side of the bed, both controlling the same ceiling light, with no second cable pulled across the room.
- At the top and bottom of the stairs — two-way switching that would otherwise need a dedicated run between the two positions.
- Just inside the door, on the side people's hands actually go to rather than the side the original wiring chose.
- On the outside of a cupboard, on glass, on a tiled splashback — surfaces that no wired switch is going into.
And it is reversible. If the position turns out to be wrong, take it off and move it. Getting a wired switch position wrong is a repeat of the whole job; getting this one wrong costs a new adhesive pad.
One switch to several lights, several switches to one light
Because the switch sends a command rather than carrying the load, the relationship between switches and lights is a setting rather than a wiring diagram. One switch can drive every fitting in a room as a group. Three switches in three doorways can all drive the same light. Two-way and three-way arrangements that would each need their own cable run are just three devices bound to the same target.
The switch does not replace app, remote or voice control — the light keeps all of them. What it adds is the thing those three are worst at: something on the wall that a guest, a child or anyone without the app can press without being told how.
Two years on one battery
These switches are designed for a two-year battery life in normal domestic use, and the reason is structural rather than clever: the switch is completely inert until it is pressed. There is no radio listening, no polling, no keep-alive. Pressing the button is what wakes the circuit, sends one short transmission and puts it back to sleep — a few milliseconds of activity per press, and nothing at all in between.
That is why a battery switch outlasts a battery sensor by years. A PIR or radar module has to stay awake to notice things. A switch only has to notice a finger, and a finger provides the power to notice it with.
Installing it so the link stays solid
The radio link is short-range and purpose-built, which is what makes it dependable in a house: it is not sharing a congested Wi-Fi channel, it does not route through a hub, and it does not depend on the internet, an account or a cloud service being up. Follow the placement rules below and it behaves like a wired switch in daily use.
- Do not stick it to metal, and do not put metal behind it. A steel back box, a metal door frame, a fridge door or a foil-backed insulation board directly behind the switch will detune the antenna. Non-metallic surfaces — plaster, wood, tile, glass, brick — are all fine.
- Keep it within the stated range of the receiver, and count walls rather than metres: a straight run across one room is nothing, three brick walls and a stairwell is a different question. Test the position before the liner comes off — press it and watch the light.
- Give it a hand's width from large metal objects in the wall or on it: a consumer unit, a steel stud, a wall-mounted television bracket, a radiator.
- Clean the surface and press it for thirty seconds. Adhesive failures on switches are nearly always dust or a cold surface, not the pad. On wallpaper, use the screw fixing instead — most of these ship with both options and the screw plate is there for exactly this case.
Where a light needs to answer to a wall switch, an app and a voice command at the same time, the mapping between all three is set in the app — which app controls your light identifies the right one for the fitting you have.
