2 Gang 2 Way Dimmer Switch - Cool Grey

Two rotary knobs on a single screwless plate, finished in cool grey with chrome controls that lift the face just enough. Each knob turns to set the brightness and presses to switch off, so there is nothing to learn. It handles up to 100W of LED lighting on each gang, and it is a two way type, so it can take its place in a circuit that is also switched from elsewhere. The front is flat and square with no screw heads on show.

We would fit this where a room needs its light level to change through the day: a sitting room that drops low in the evening, a bedroom, a dining room where the table wants a softer setting. Because it covers both circuits from a single position, it suits a room with a pendant and a run of downlights, or a hall and landing controlled side by side. It is intended for indoor domestic lighting circuits, and it is worth checking that the lamps or drivers on those circuits are marked dimmable, since plenty are not. Grey plates hold their own against darker paint and against greys and taupes, where white can jump out.

The plate and knobs are moulded ABS, double insulated, and light enough to feel unfussy in the hand. It carries a ten year warranty. For cleaning, switch off at the consumer unit, then wipe the plate with a dry or barely damp cloth; household sprays and solvents can dull the moulding, so keep them clear. We stock it in this cool grey with chrome knobs, and it sits comfortably beside chrome sockets and cool grey plates elsewhere in the room. It is one we reach for when a plain on and off switch leaves a room feeling too bright.

What size is the plate?

The plate measures 88mm square, with a back box depth of 35mm behind it.

How much lighting can each knob control?

Each gang is rated for up to 100W of LED lighting.

Will it dim any LED lamp?

Only lamps or drivers marked as dimmable will dim correctly. Non-dimmable LEDs may flicker, buzz or refuse to start, so check the lamp packaging before you buy.

Can it be used where a light is switched from two places?

Yes. It is a two way rotary dimmer, so it can be wired into a circuit that is also switched from another position.

Is it suitable for a bathroom or an outbuilding?

No. It is rated IP20 and made for indoor domestic lighting circuits in dry rooms.

What is it made from, and how should it be cleaned?

The plate and knobs are moulded ABS, double insulated. Isolate the circuit, then wipe with a dry or barely damp cloth and avoid solvents or abrasive cleaners.
