Each gang operates independently via a rotary push-on control knob that dims when rotated and switches on or off when pressed. The matt white screwless faceplate sits flush against the wall with no visible fixings, presenting as a single clean panel with four matching white dimmer knobs.\u003c\/p\u003e\n\u003cp\u003eDesigned for hallways, living rooms, dining rooms and open-plan spaces where four separate lighting circuits need individual dimming control, the intelligent circuitry automatically detects and adjusts to different load types. Each dimmer can switch between trailing-edge and leading-edge modes via the front control knob, making it compatible with most dimmable LED, CFL and incandescent lamps without needing to access the back box. The trim, mode switch and reset functions are all accessible from the front of the plate, allowing adjustments if lamp types are changed after installation.\u003c\/p\u003e\n\u003cp\u003eThe premium-grade steel construction and matt white finish provide a neutral backdrop that pairs with both cool and warm interior palettes. The 4.3mm projection from the wall is minimal, and the screwless cover plate clips onto a separate metal sub-frame fixed to a 25mm minimum back box. Built-in overload and overheat protection shut down each gang independently if a fault is detected, and an inrush current limiter (ICL) prevents surge damage when lamps are first switched on. The dimmer is preset in trailing-edge mode on delivery, which suits most modern dimmable LED lamps.\u003c\/p\u003e\n\u003cp\u003eEach gang must control lamps of the same brand, type and wattage — mixing different lamp brands or wattages on a single gang will cause flickering or failure to dim correctly. The 2-way wiring configuration allows the same lighting circuit to be controlled from two locations (e.g. top and bottom of stairs, opposite ends of a hallway).\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e87.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e147.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e4.3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e21.3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.
