The Soho Lighting Charterhouse Collection 4 Gang Dimming Toggle Switch features four independent dimming toggles on a single antique brass plate. The metal is plated, brushed, and aged to achieve a warm, period-correct aesthetic that naturally masks fingerprints and small surface marks. As part of the Charterhouse range, this switch utilises a screwless faceplate, providing a clean and seamless profile by concealing all internal fixing screws.

Each of the four gangs is powered by the award-winning Enkin IDM250 in-line 250W LED dimmer module. This technology includes a soft-start function that gradually brings the lights to the set level over one to two seconds, which helps to prolong the life of the lightbulbs. The modules feature flicker-free technology, short circuit protection, overload protection, and a self-recovering thermal fuse. Each module also offers a simple push-button setup and is backed by a five-year guarantee.

The IDM250 module can control up to 250W of LED lighting per circuit and supports multi-point dimming when used alongside additional toggles or rockers. For multi-point configurations, only one IDM250 module is required per circuit. This 4-gang unit allows for the sophisticated atmospheric control of four separate lighting zones, combining modern electrical reliability with a traditional toggle design that coordinates with other antique brass hardware, such as kitchen handles and door furniture.
