Duroplast Dimmer Round
A modern dimmer in the style of European switches of the 1920s and 30s, made from one of the classic materials of the era: Duroplast, the “white Bakelite”. This design features a more authentic round backplate (which requires a round back box).
This dimmer is available in four versions, depending on your light source:
- LED of combined loads from 3W to 35W, “Leading Edge” or TRIAC
- LED of combined loads from 5W to 85W, “Leading Edge” or TRIAC
- LED of combined loads from 5W to 150W, “Trailing Edge”
- Conventional dimmer for incandescant and halogen bulbs
Electronic dimmers (suitable for LED transformers for example) are also available – please get in touch if you require this type.
For combining these dimmers to create multiples (3-gang, 4-gang etc), you can use modular backplates that join at the ends. Please contact us for more information. NB: these multiples will only fit onto European back boxes, not British rectangular double boxes.
The modular nature of these dimmers also 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 handle, 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.
UK power sockets
Unfortunately this style doesn't have UK socket options yet.
Because of its round backplate shape, this switch doesn’t fit the regular British square or rectangular wall boxes. The corners of the back box (or the hole the switch is going into) WILL SHOW.
It is perfectly possible to fit a European-style round back box, which the backplate will cover. We sell these boxes here. But this will require electrical work and decorating/plastering to make good the new wall box.
Please be aware that we don’t accept returns of this product if you find that the necessary installation/decorating work is too extensive. We kindly ask that you and your electrician make sure that they are aware of the back box incompatibility before ordering this product.
What’s in the box?
This dimmer set consists of an insert (including rotary knob), and a round frame.

What does an electrician call this?
This is a 1-gang 2-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).
THPG dimmer switches are easy to install, but remember, the round backplate versions don’t fit onto standard British back boxes! Just follow the step-by-step pictures below or download the PDF with full instructions.

Does this cover a standard british back box?
No, a 70mm round back box is required. Check the available options below.
How deep does the back box need to be?
This insert is quite deep, it needs at least 45mm. Check the available options below.
Drawing on the popular switches of the early 20th Century, THPG Bakelite 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 the round or square backplate shapes, the elegance of a by-gone era shines through in these pieces. It’s a dimmer switch that will be talked about in your house.
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.
Bakelite has a unique look and is loved for its semi-glossy, silky finish and a tactile surface that is 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 electronic dimmer insert in this product is a high-tech unit, which can control any modern light source without flickering or unpleasant noises. It should work “out of the box”, but it can also be configured by your installer if necessary.
Old-school allure and craftsmanship – a contemporary icon
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.
The beauty of our Bakelite switches lies in their utilitarian, old-school allure. They could be sitting on a modern grey wall, providing a contrast with cocooning dark blue tones, or finishing off a period wall in floral flock or vintage prints, this switch is a versatile classic in its own right.
So whether you are planning an authentic restoration of a period property, or looking for a playful addition to your minimalist or mid-century modern interior scheme, this monochrome range of toggles and rotaries adds eye-catching architectural accents.
