A single pull switches the light on or off; holding the cord dims the light up or down to the desired brightness. The switch includes a built-in potentiometer for tuning the dimming curve to match specific bulb types, reducing flicker and improving compatibility.\u003c\/p\u003e\n\u003cp\u003eDesigned for bathrooms, bedrooms and other rooms where wall-switch access is impractical, the pull cord extends 1.5m from the switch body, allowing it to be mounted on a ceiling or high on a wall with the cord hanging within reach. The 75mm diameter circular body is 36mm deep and fits ceiling roses or surface-mounted back boxes. The trailing edge technology works best with dimmable LED and low-voltage halogen lamps; always verify compatibility with the lamp manufacturer before installation.\u003c\/p\u003e\n\u003cp\u003eThe smoked bronze finish is a dark metallic tone partway between gunmetal and aged brass, providing a contrast accent against white ceilings or pairing with darker interiors. The body is constructed from premium-grade steel and ABS, rated Class II (double-insulated) with IP20 protection for dry indoor locations. The switch is certified to EN 60669-2 and carries a 2-year warranty.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e75 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e36 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePremium grade steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction 2\u003c\/td\u003e\n\u003ctd\u003e\u0026amp; ABS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eSmoked Bronze\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClass\u003c\/td\u003e\n\u003ctd\u003eII\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd\u003e230V 50Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable Length\u003c\/td\u003e\n\u003ctd\u003e1.5 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_4959630_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/manual_1363696.pdf\" target=\"_self\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between trailing edge and leading edge dimming?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTrailing edge dimmers (like this model) reduce voltage at the end of each AC waveform cycle, making them compatible with most dimmable LED and electronic low-voltage transformers. Leading edge dimmers cut the start of the waveform and work better with traditional incandescent and mains-voltage halogen bulbs. Trailing edge technology reduces buzzing and flicker with modern LED lamps.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this be used in a bathroom?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, provided it's installed outside bathroom zones 0, 1 and 2 as defined by Part P Building Regulations. The IP20 rating means it must not be exposed to direct water spray. Most bathroom installations mount the switch on the ceiling outside the shower\/bath zone with the pull cord hanging within reach.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow is the dimming curve adjusted?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe built-in potentiometer is a small dial or screw adjustment accessible on the switch body (see the product manual for exact location). Turning the potentiometer changes the minimum and maximum brightness levels, allowing the dimmer to be tuned for specific bulb types and reducing flicker or dropout at low settings.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat happens if I use it with a non-dimmable LED bulb?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNon-dimmable LED bulbs may flicker, buzz, or fail to dim smoothly when used with this switch. Always use dimmable-rated LED bulbs and verify compatibility with the bulb manufacturer. Some budget dimmable LEDs also perform poorly; branded dimmable LEDs from Philips, Osram or similar tend to give better results.\u003c\/p\u003e","brand":"Knightsbridge","offers":[{"title":"Default Title","offer_id":45293653393675,"sku":"8301SB","price":24.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/1068332_248eaa5a-298f-4939-a870-a87ab69ad618.jpg?v=1714661910","url":"https:\/\/niori.co.uk\/products\/1-way-10-150w-trailing-edge-pull-cord-dimmer-switch-smoked-bronze","provider":"Niori","version":"1.0","type":"link"}
