1 Gang Momentary Switch Invisible Plate with Stainless Steel button, Single Gang Button Dimmer Controller

This is the Forbes and Lomax 1GBELL/S, a one gang momentary switch invisible plate with stainless steel button, single gang button dimmer controller, manufactured by Forbes and Lomax. 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.

All momentary switches (contact-closure switches) require an in-line dimming pack to enable them to work as a dimmer, or a relay pack to have an ON/OFF function. The button dimmer controller allows dimming from more than one location, and it can be used to control home automation systems.
