Each gang features a push on\/off rotary knob that dims the connected load when turned, with automatic trailing-edge or leading-edge mode selection depending on the lamp type connected.\u003c\/p\u003e\n\u003cp\u003eDesigned for multi-zone residential and hospitality installations where different lighting circuits need independent dimming control, the 4-gang configuration allows separate control of ambient ceiling lights, task lighting, accent lighting and decorative fittings from a single wall position. The 2-way function allows the same lighting zone to be controlled from two different wall locations when paired with a compatible 2-way switch.\u003c\/p\u003e\n\u003cp\u003eThe antique brass screwless faceplate provides a warm, aged metallic finish with a brushed texture that hides fingerprints and minor surface marks. The screwless design uses a cover plate that clips onto a separate metal sub-frame, so no visible screws appear on the wall once installed. Each rotary knob includes trim adjustment, mode switching between trailing-edge and leading-edge, and a reset function accessible from the front of the plate. Built-in overload and overheat protection prevents damage if the connected load exceeds the rated wattage.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e87.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e147.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e43.9mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e22.6mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e21.3mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.

This dimmer automatically detects which mode is needed when powered on, but the mode can be manually switched via the rotary knob if needed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I mix LED and halogen lamps on the same gang?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. Each gang should control a single lamp type and brand. Mixing different lamp technologies or wattages within the same circuit can cause flickering, buzzing, or premature dimmer failure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat back box depth is required?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA 25mm minimum back box depth is needed. The dimmer module projects 21.3mm into the box, with the screwless cover plate adding 22.6mm of projection from the wall once fitted.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I set the minimum brightness level?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEach rotary knob has a trim adjustment accessible from the front. Remove the knob, adjust the trim screw to set the minimum dimming level, then replace the knob.
