The dual USB ports share a 5V DC 4.0A output, allowing two devices to charge simultaneously without needing a separate plug-in adapter.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential and light commercial installation, the socket fits standard 25-35mm back boxes depending on cable entry configuration. The single-pole switching isolates the live line when switched off, suitable for standard appliance loads up to 13A per outlet. The rounded edge plate sits flush to the wall with a subtle 7.5mm projection, while the brushed chrome finish provides directional grain that softens reflections and fingerprints compared to polished chrome.\u003c\/p\u003e\n\u003cp\u003eThe white insert behind the chrome faceplate defines each outlet aperture and gives a crisp contrast against the metal surround. The faceplate is constructed from premium-grade steel with a protective lacquer over the brushed finish, maintaining its appearance in high-traffic areas. The USB-C port supports modern fast-charge protocols for phones and tablets, while the USB-A port retains compatibility with older cables and devices.\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\u003e85.75 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e146.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e7.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.

Tighter cable bends or rear entry may require the deeper 35mm box, while side entry and neater wiring can work with 25mm.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between SP and DP switching?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSP (single-pole) switching isolates only the live line when switched off, which is standard for most residential sockets. DP (double-pole) switching isolates both live and neutral, providing additional safety for high-draw appliances or bathroom zones. This socket uses SP switching.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the USB charging output?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe dual USB ports share a total 5V DC 4.0A output. When both ports are in use, the 4.0A is split between the two devices. For optimal charging speed, use certified USB cables that match your device manufacturer's specifications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the rounded edge plate removable for redecorating?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The faceplate is fixed with screws visible from the front (this is not a screwless design). It can be removed for painting around the socket and refitted without re-wiring, though the visible screw heads will remain part of the design.\u003c\/p\u003e","brand":"Knightsbridge","offers":[{"title":"Default Title","offer_id":45293692748043,"sku":"CL9940BCW","price":18.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/1540068_5ba55757-1560-4146-8e3d-c5cc2078bd78.jpg?v=1714662682","url":"https:\/\/niori.co.uk\/products\/13a-2-gang-sp-switched-socket-dual-usb-a-usb-c-brushed-chrome-white-insert-rounded-edge","provider":"Niori","version":"1.0","type":"link"}
