Knightsbridge ML accessories, SF1200,MBB. A matt black, screwless 10AX 1G intermediate switch.
An intermediate switch is used when you have three switches controlling one light. A typical example of this is on a landing. There is a switch at the bottom of the stairs, one at top of the stairs and one at the end of the landing. On this circuit you would need the middle switch to be intermediate in order for all the switches to function properly.
Flawless Screwless low profile metal design with matching metal rocker.
