This is the X4GT3DIM 4 Gang Mixed Plate: 3x Dimmers and 1x Dolly Invisible Plate Forbes and Lomax (Dolly and Dimmer Modules Ordered Separately) available at Sparks Electrical Wholesalers for the best price. 

Note: It comes with the grid transparent perspex plate, the knobs, collars and rings - but not the modules, which need to be ordered separately. You need to select the finish of the insert (by default is brass, it can also come in Antique Bronze, Stainless Steel, Brushed Brass, or Nickel - mention this at the checkout) for the dimmer and the dolly switches. See the required items.

You can choose the code for your required mix of dolly (T) and dimmer module (DIM) along with the finish and then pick the modules in the required list. This is a 4 gang invisible plate taking 1 dolly switch module and 3 dimmer modules - the toggle modules and the dimmer module need to be ordered separately. 

Please note: by default, the insert is unlacquered brass; it is shiny/polished brass, which after time becomes aged brass (there is a patina), which can be polished to become shiny again. The insert is unlacquered, designed to mellow with age if left unpolished to match older brass fittings in the home.

4 Gang Mixed Plate: 3x Dimmers and 1x Dolly Invisible Plate - Features

  • If you already have a particular finish of Forbes and Lomax at home and you wish to add more modules, this is one of the "mix-and-match" plates - you can select the desired plate and the required modules to obtain the item you require.
  • The Invisible plate is inspired by the 1930s glass switches but with all the advantages of modern technology, the Invisible Lightswitch has become synonymous with Forbes & Lomax.
  • Switches and dimmers have 3mm bevelled transparent acrylic plates which are secured without the use of fixing screws.
  • The plates are flush to the wall and are supplied with brass, nickel silver, stainless steel or antique bronze toggle switches, dimmer knobs or buttons.
  • 0.5mm 'inner plates' of primed aluminium sit behind the Invisible plates which can be decorated in the same way as the walls giving the illusion that the wallpaper or paint finish runs seamlessly behind the switch plate.
  • Invisible plates and rocker switches with 2mm thick acrylic plates complete the range.
