The Forbes and Lomax Dolly Switch

The Forbes and Lomax Dolly Switches are On/off Switches available in 2-way, Intermediate and double pole versions. Retractive dolly switches can be used as dimmer controllers when connected to a dimmer pack or dimming system. 2-way-and-off switches can be used to operate blinds.

The Forbes & Lomax dolly switches are available in: the Invisible Lightswitch® Range, the Antique Bronze Range, the Stainless Steel Range, the Aged Brass Range, the Unlacquered Brass Range, the Nickel Silver Range, and the Verdigris Range.

  • Invisible plates and rocker switches with 2mm thick acrylic plates complete the range.
  • The Forbes and Lomax Momentary / contact closure switches require an in-line dimmer pack to enable them to work as a dimmer. They can be used for lighting control and home automation systems. The dimmer pack has to be located in an accessible void, out of earshot; any noise generated when dimming will come from the dimmer pack - no noise will be emitted from the switch itself. 
  • You can achieve multiple switching locations on one lighting circuit by wiring the buttons in parallel; all the locations must have momentary controls, and each location can be used to dim. However, you cannot use normal switches on the same circuit as the button dimmer. 
  • To use a momenary control as a simple ON/OFF switch, you need to put a link to the in-line relay pack. 

Please note: The button dimmer / momentary switch will only work in conjunction with an inline dimmer (see the required items). The way it works is: one in-line dimmer (impulse dimmer) per button dimmer. For 50-1000W 4A dimming you can order the ID0401 and for LED dimming you can use ID0101LE. 

The Invisible Range from Forbes and Lomax

  • Inspired by the glass switches of the 1930s but with all the advantages of modern technology, the Invisible Lightswitch has become synonymous with Forbes & Lomax.
  • The transparent acrylic plates are secured without the use of fixing screws. The plate sits flush to the wall and is supplied with brass, nickel silver, stainless steel or antique bronze switches or dimmers.
  • Each acrylic plate has a 0.5mm underplate which can be either painted or used as a template where wallpaper is used.
