This Part M grid panel combines an intelligent dual mode dimmer with a 20A 2 way switch on a single graphite front plate with white rockers.
Part M of the Building Regulations requires that switches can be seen and located easily by people with impaired vision, and contrast is how that is achieved. The graphite plate stands out against a light-coloured wall and the white rockers stand out against the plate. There is no visible plastic around the rockers and the screws are colour matched, so nothing interrupts the contrast. The front plate matches the power products across the Part M range.
The dimmer gives smooth control of light levels with silent operation. It is switchable between trailing and leading edge, so it works with dimmable LED, halogen and incandescent lamps rather than being limited to one type. Soft start brings the lights to the set level in around one second, which extends lamp life, and support for lower wattage lamps eliminates flicker. Overload protection means that if too many lights or transformers are connected, the dimmer turns the lights down or off until the load is corrected rather than failing. Control is 2 way push on/off with a rotary dial. Please check that your lamps are marked dimmable.
The second module is a 20A 2 way single pole switch, suited to operating lights from two positions such as the top and bottom of a staircase or either end of a hallway. It can also be wired as a one way switch on its own.
Modules locate and clip into the grid frame, with captive backed-out terminal screws for fast installation. Requires a standard UK back box with a minimum depth of 25mm.
Please note that this switch will come in a grid format.

Your grid switch arrives as a kit: a front plate, a metal grid frame and the switch modules you chose. Modules clip into the frame, the frame screws to the back box, and the plate fits over the top.
Safety first: Only fit this yourself if you are competent to do electrical work. Work must meet BS 7671, and some jobs (for example new circuits, or work in bathrooms) are notifiable under Part P in England and Wales. If in doubt, use a registered electrician.
- Switch the circuit off at the consumer unit and confirm it is dead with a voltage tester before touching any wiring.
- Unscrew the old switch, take a photo of the wiring and label which cable goes to which terminal.
- Check the back box is deep enough: at least 25 mm for switches, 35 mm for dimmers and larger plates (see the spec sheets below).
- Clip each module into the grid frame from the front, in the order shown on this listing, with the 'TOP' marking facing up.
- Wire each module: one-way uses COM and L1, two-way uses COM, L1 and L2, and an intermediate takes both pairs of strapper wires. For dimmers and 20A modules, follow BG's leaflet below.
- Connect the earth (green/yellow) cable to the earth terminal on the grid frame or metal plate.
- Screw the grid frame to the back box, then fit the front plate. Screwless plates clip over the frame.
- Switch the power back on and test every switch and dimmer.
