4 Gang 250W Loading Rotary Dimmer in Invisible Plate with Brass Knob on a Quad Plate

This is the Forbes and Lomax 4GRD250, a four gang 250W loading rotary dimmer coming in an invisible plate with brass knob, manufactured by Forbes and Lomax - on a quad plate (a square double size plate).

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.

Please note: this is a 4 gang rotary dimmer with push on/off switch function using rotary knobs on a square double plate, fitting the ALM893 back box. The knobs have the function of both of switching ON/OFF only and of dimming (max. 250W per gang).
