13A 2 Gang SP Switched Socket Dual USB-A & USB-C - Polished Brass Screwless (Black Insert)

The Knightsbridge 13A 2-gang SP switched socket adds one USB-A and one USB-C charging port behind a polished brass screwless faceplate with a black insert. The single-pole switching controls the live line only, suitable for standard residential loads where dual-pole isolation is not required. The USB ports share a 5V 4A output, providing up to 20W of charging power split between connected devices.

Designed for residential and hospitality installation, the socket fits a standard 25-35mm back box depth depending on wiring conditions and uses a screwless cover plate that clips onto a separate metal sub-frame. This means there are no visible screws or fixings on the wall once installed, giving a cleaner finish than traditional screw-fixed plates. The built-in gasket sits between the sub-frame and the cover plate, preventing dust ingress around the edges and maintaining a tight seal against the wall surface.

The polished brass finish provides a warm metallic accent that pairs well with traditional, classical and warm-toned contemporary interiors. The black insert behind the brass faceplate hides the back of the cover plate and gives a defined edge to each outlet aperture. The premium-grade steel construction provides a substantial feel at 4.3mm projection from the wall once fitted, thinner than standard screw-fixed plates. The IP20 rating confirms this is an indoor socket not rated for bathroom zones or outdoor use.

Product Specification Sheet

What back box depth is required?

A 25-35mm back box depth is needed depending on wiring conditions. The screwless cover plate adds 4.3mm of projection from the wall once fitted, making this one of the slimmer profiles in the Knightsbridge range.

What's the USB charging output?

The USB-A and USB-C ports share a 5V 4A output, providing up to 20W total charging power. When both ports are in use, the 4A is divided between the two devices. Knightsbridge recommends using certified USB cables to ensure safety and compatibility.

What's the difference between SP and DP switching?

SP (single-pole) switching controls the live line only. DP (dual-pole) switching isolates both live and neutral lines when switched off, providing additional safety for high-draw appliances. This SP model is suitable for standard residential loads where DP isolation is not required.

Is the screwless plate removable for redecorating?

Yes. The cover plate clips onto a separate metal sub-frame fixed to the back box. The cover can be removed for painting around the socket and re-clipped without re-wiring. The built-in gasket maintains a dust-tight seal when refitted.
