Manufactured by Rosenthal, Serie 1930 is a switch that represents a tangible piece of design history. This finish has the classic, slightly off-white gloss of high-grade porcelain.
Apart from switches, Berker 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.
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 switch set consists of a rotary switch insert, an outer frame and a front plate with screw-in porcelain knob.

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 1-way switch controls two light sources from the same switch but those lights can not be controlled from elsewhere (a slightly old-fashioned wiring type).
THPG rotary 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 go to our THPG rotary switch installation page. We used a European round box in the pictures but the procedure is the same for square ones.

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.
The blueprint for this classic rotary switch is one of the original Bauhaus switches from the 1930s, which Berker had already reissued in 1999 in a plastic edition (and which can be found, amongst other places, in the Dessau Bauhaus, renovated true to its original state).
But the real feature of this collection is the fine Rosenthal porcelain, manufactured in a factory with a long tradition in iconic ceramics pieces.
The high gloss porcelain and the typically 1930s round backplate – slightly wider and flatter than the THPG switches of a similar era – make this a real statement piece. The black centre screw (instead of the standard silver) is just one of the little design details that makes this stand out from other similar products.
The whole piece is noticeably heavier than plastic switches, which gives it a traditional and durable feel. The rotary turns smoothly and quietly and makes this switch a joy to use.
A stylish return to the roots of classic switch design
The name Rosenthal has been synonymous with artistic flair and design, intricate craftsmanship and perfect porcelain for over 130 years. Many iconic pieces of tableware, created by artists and designers such as Dalí, Warhol, Wagenfeld and Gropius, made their brand a global success. In 2010 Rosenthal started collaborating with Berker on a range of porcelain switches, expertly forged in that luxurious material sometimes referred to as “the white gold”.
Fired and glazed porcelain is extremely robust and scratch-proof (which is a useful attribute for a light switch), but even though these pieces are built from industrial-strength ceramics, there is also still plenty of manual work involved in the production.
The history of these switches is steeped in the 1930 interior styles of the Bauhaus period, but that doesn’t mean it’s purely for faithful restorations or retro-style houses. The luxurious and at the same time industrial porcelain works in modern surroundings just as well.
One thing that we always notice in projects that are accessorised with these pieces is that the round, black or white accents on the wall add an eye-catching detail wherever you decide to use them,
