You must use our back boxes to install our Kew switches and sockets. They’re deep enough to hold all the electrics inside, and the design means the plate sits in the correct position every time.
You can fit this double back box into masonry or stud walls. It has tabs and a lip that grip the plasterboard securely when installed into a cavity.
It’s also made from fully recycled and recyclable post-consumer plastic.
We sell 9mm and 3mm trims to add to your back box so you can render or skim it into the wall for a perfect finish. The box comes with a cover that allows you to do this without getting plaster inside.
- Patented electrical system engineered to make our signature flush-fit design possible
- Made from recycled and recyclable post-consumer plastic
- Quick and easy to fit
- You’ll need one of our 71mm hole saws to install our back boxes
- Fire retardant

Four-way switches need to be used when three or more switches are required to control the same light. Three-way switches are used at the start and end of the circuit, and one or more four-way switches are added to the middle of the circuit.
Multiple three-way dimmer modules can't be used to control the same light. However, a three-way dimmer can be combined with three-way or four-way switches to control the light from multiple locations.
Retractive and center retractive toggles/rockers can be used for a multiple point dimming circuit when used with an in-line dimmer module (one per circuit).
All our dimmers have been engineered with anti-flicker technology. If you're experiencing flickering, please follow our mode setting instructions.
