Kew collection
Must be used with our bespoke back boxes.
These switches and sockets are our subtlest. To get a flush finish, they’re fitted with our own back boxes that are deep enough to house all the electrics.
Grove collection
Suitable for use with most standard back boxes. Check the required back box depth listed on the product page (this varies by product) to ensure compatibility.
The switches and sockets in this range are precisely machined for crisp, clean edges. We’ve engineered them to work with existing back boxes, so they’re ideal for retrofitting (they simply clip in place).

A retractive switch flicks back into the top 'off' position when you let go. A center retractive switch flicks back to the center 'off' position when you let go. It can be pressed up or down to make two separate connections.
When used with one of our in-line dimmer modules, a short press will turn the light on and off. A press and hold will dim and brighten the light.
Both versions must be used with one in-line dimmer module per circuit.
Intermediate switches need to be used when three or more switches are required to control the same light. Two-way switches are used at the start and end of the circuit, and one or more intermediate switches are added to the middle of the circuit.
Multiple two-way dimmer modules can't be used to control the same light. A two-way dimmer can be combined with two-way or intermediate switches to control the light from multiple locations.
Retractive and centre retractive toggles/rockers can be used for a multiple point dimming circuit when used with an in-line dimmer module (one per circuit).
Alternatively, our multiway dimmer module can be used to dim and turn lights on/off from multiple locations on one circuit.
All our dimmers have been engineered with anti-flicker technology. If you're experiencing flickering, please follow our mode setting instructions.
We ship the components and front plates separately to protect the plates before installation. This approach allows electricians to install the switches and sockets without having to disassemble each one too.
