The single-pole switch isolates the live line when the socket is switched off, while the dual USB ports provide 5V DC 2.1A shared output for charging phones, tablets and other portable devices without needing a separate plug-in adapter.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential and commercial installation, the socket fits mounting boxes with 25-35mm depth depending on wiring configuration, making it compatible with most standard UK back boxes. The square edge metal plate sits flush with the wall, and the built-in gasket ensures a tight seal against the mounting surface. The black insert behind the faceplate hides the back of the cover plate and provides a defined edge to the socket aperture and USB ports.\u003c\/p\u003e\n\u003cp\u003eThe brushed chrome finish is applied to premium-grade steel, giving a directional grain that softens reflections and resists fingerprints better than polished chrome. The metal rockers match the faceplate finish, maintaining a consistent appearance when the socket is in use. The 13A rating handles standard UK appliance loads up to 2,990W, while the IP20 rating confirms suitability for dry indoor locations.\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\u003e89 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e89 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e10.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.

Most standard UK single-gang back boxes at 25mm or 35mm are compatible.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the USB charging output?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe dual USB-A ports provide 5V DC output with a combined maximum of 2.1A shared between both ports. This is suitable for charging smartphones and tablets, though fast-charge protocols are not supported.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does SP switching mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSP stands for single-pole switching, which isolates the live line when the socket is switched off. The neutral line remains connected. This differs from DP (double-pole) switching, which isolates both live and neutral.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the square edge faceplate removable for redecorating?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The faceplate is screw-fixed to the mounting box and can be removed to paint or paper around the socket, then re-fitted without re-wiring. The built-in gasket ensures a clean seal when re-installed.\u003c\/p\u003e","brand":"Knightsbridge","offers":[{"title":"Default Title","offer_id":45293779583243,"sku":"CS91BC","price":11.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/321256_5348f5d9-410a-49cc-a093-6330acbe58ed.jpg?v=1714664012","url":"https:\/\/niori.co.uk\/products\/13a-1-gang-sp-switched-socket-dual-usb-brushed-chrome-square-edge-black-insert","provider":"Niori","version":"1.0","type":"link"}
