Product Story

An updated, European twist to the traditional dolly switch in an authentic satin white resin, often referred to as “white Bakelite”. This particular design features a square backplate, which makes it a great companion for standard British back boxes.

Product Options

For combining these switches to create multiples (3-gang, 4-gang etc), you need a 2-gang backplate – see below. Please contact us for more information. NB: these combinations will only fit onto European double backboxes, not standard British rectangular ones.

The modular nature of these switches mean that you can also mix and match finishes! Please get in touch if you would like to combine a Bakelite frame with a contrasting Duroplast toggle, for example.

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 you need to know

What’s in the box?

This switch set consists of an insert including toggle, a square frame and a smaller round front plate, fixed with a small metal screw.

What does an electrician call this?

This is a 1-gang 2-way 10AX switch, or 2-gang 1-way 10AX switch, or a 1-gang intermediate 10AX 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). A 2-gang switch is used for controlling two light sources from one or two places.



THPG toggle 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. We used a European round box in the pictures but the procedure is the same for square ones.

Like all THPG switches, these have open screw fittings for the wiring. Because in UK installations both line and neutral wires are permanently live, it is especially important to make sure the power to the switch is switched off at the consumer board during installation!

Does this cover a standard british back box?
This product covers a standard knockout box, but it doesn't cover the flanges of standard drywall boxes. We recommend using "flat plate" drywall boxes or European round boxes.

How deep does the back box need to be?
This needs a slightly deeper box, at least 35mm.

The concept

Drawing on the popular switches of the early 20th Century, THPG Duroplast switches are designed to recreate a vintage look with a clean, sleek finish. They are faithful replicas – in fact made using original machinery and processes – but they don’t come across too old-fashioned to be a charming focal point in a modern interior either.

Whether in this round backplate design, or the round one, the elegance of a by-gone era shines through in these pieces.


The detail

Duroplast, like Bakelite, has a unique feel. Its semi-glossy, silky finish and tactile surface are hard to resist. It feels "warmer" than modern plastics and this quality is used to great effect in the soft and friendly shapes of the THPG switches.

The small screws that hold the parts together are sunken into the resin, not to distract from the gently curved look of the piece.

Old-school allure and craftsmanship - a contemporary icon

the range

Available in a striking monochrome palette, the THPG Bakelite and Duroplast designs come in round or square frames. Central toggles and rotaries provide a pleasing focal point, drawing the eye into the centre of the switch. The toggles can be ordered in single or double versions but even if you require a "double" rotary, get in touch - there are options!

The round frames in this collection work brilliantly with our Porcelain Button and Porcelain Rotary ranges (also by THPG), allowing you to create interest with different textures and materials whilst retaining a unified shape. Square frames make a bolder statement and also have the advantage of being able to be installed into standard UK back boxes.

The source

Working in partnership with manufacturers in Westphalia, THPG have restored original moulds and reintroduced traditional specialist tools in order to create a truly authentic, top quality Bakelite light switch. Their highly skilled artisans, chosen for their experience working with this material, hand-finish the mechanical inserts and covers in a factory that has been making products for several hundred years.

Due to the 'matrix method' of moulding, along with the inherent durability of Bakelite, these switches are built to last. Once the material has been pressed and moulded it will retain its shape forever. The collection has a superior look and feel, and its internal functions are just as effective and efficient as those we can see and touch.
