Description
The Knightsbridge 5A unswitched round pin socket features a polished chrome faceplate with a white insert, designed for low-current lighting circuits and specialist applications. The socket accepts BS 546 round-pin plugs and provides an earth terminal connection, making it suitable for custom lighting installations, vintage appliance connections, and specific commercial fit-outs where 5A round-pin infrastructure is specified.
Installed in lighting control systems, theatre tech rooms, gallery exhibition spaces, and older properties retaining original round-pin circuits, the socket suits both modern and period interiors. The ultra-flat profile sits just 2.5mm proud of the wall surface once fitted to a standard 25mm back box, giving a discreet finish against plaster or tiling. The polished chrome reflects ambient light and pairs with chrome taps, door furniture and appliance finishes in kitchens and bathrooms rated IP20 or higher.
The 201 stainless steel construction provides corrosion resistance in environments with elevated humidity, though the IP20 rating limits the socket to dry indoor zones only. The white insert behind the chrome faceplate hides the back of the plate and defines the edge of each pin aperture. The built-in gasket between the plate and the wall surface helps prevent dust ingress behind the faceplate over time. Knightsbridge backs this socket with a 25-year guarantee covering material and finish defects.

Frequently Asked
What is a 5A round pin socket used for?
5A round pin sockets are typically used for low-current lighting circuits, vintage appliance connections, and specialist installations where BS 546 round-pin infrastructure is specified. They are less common than standard 13A rectangular-pin sockets but remain in use in period properties, theatre tech rooms, and gallery lighting systems.
Can this socket be used in bathrooms?
The IP20 rating limits this socket to dry indoor zones only. It cannot be installed within bathroom zones 0, 1, or 2 where water contact is possible. For bathroom installations outside splash zones, consult an electrician to confirm suitability under current wiring regulations.
What back box depth is required?
A minimum 25mm back box depth is required for safe installation. The socket recesses 21.1mm into the back box and projects just 2.5mm from the wall surface once fitted.
Is this socket switched or unswitched?
This is an unswitched socket. Power flows to the socket whenever the circuit is live at the consumer unit. If switching is required, it must be provided upstream via a fused connection unit or separate wall switch.
