This is the Forbes and Lomax X4GRD250/AB, a a four gang rotary dimmer - 2 x 250W and 2 x 400W loading dimmers - coming in an invisible plate with antique bronze knobs, manufactured by Forbes and Lomax - on a twin plate (a two gang 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.
Please note: this is a 4 gang rotary dimmer with push on/off switch function using rotary knobs on a double plate, requiring a double back box. The knobs have the function of both of switching ON/OFF only and of dimming. They are not suitable for LED dimming - this is not an LED dimmer (see X4GTE250/AB for the corresponding LED dimmer).
