The popular THPG Porcelain range now has a toggle switch version too. Porcelain fittings were common in the 1920s, when wall-mounted switches started becoming more affordable.
The surface of these beautiful hand-finished pieces is a pure black, which complements matt painted walls as well as period wallpaper and is also a great companion to the off-white original of this range.
NB: These switches are meant to be fitted into European back boxes, not standard British rectangular ones.
Please review the “What You Need To Know” section below for essential product details, dimensions, fitting info and more.
Apart from switches, THPG offer a selection of wiring products and functions that can be combined with these frames, such as audio speaker inputs, TV/SAT sockets and network sockets. Contact us for information on other options if you can’t find what you’re looking for.

What does an electrician call this?
This is a 1-gang 2-way 10A single pole switch, or a 1-gang intermediate 10A single pole switch
Where is this used in the home?
A 1-gang 2-way switch is commonly used for controlling a single light source from one or two places. A 1-gang intermediate is used as the middle switch of three, controlling a single light source (for example in a hallway).
Installation
THPG rocker switches require a bit more patience to wire up, simply because they are modelled on original designs and don’t have the modern conveniences of push-contacts and encapsulated backplates.
Just follow the step-by-step pictures below or go to our “THPG toggle switch installation page. Like all THPG switches, these have open screw terminals. IMPORTANT: Don’t over-tighten the brass screws, it could cause the porcelain centre plate to split.
NB: We used a European round box in the step-by-step pictures, but the procedure is the same for square UK boxes.

The source
THPG have brought together a producer of electro-technical switches from Westphalia and a producer of electro-technical porcelain from Thuringia. The result is this porcelain switch system: it is both functional and pleasant in three ways: to the eye, to the touch and to the ear
All porcelain parts originate from Schierschnitz in Thuringia, where electro-technical porcelain has been produced since 1913. The porcelain is moulded under a pressure of 35-40 MPa into metal mouldings, then glazed and sintered at a temperature of 1320-1330° C.
