Berker Serie 1930 White Porcelain Dimmer


Product Story

Using ceramics manufactured by Rosenthal, the dimmer of the Serie 1930 design range represents a tangible piece of design history. Its surround features the classic, slightly off-white gloss of high-grade porcelain, while the centre button is made of Duroplast (“White Bakelite”).

Electrician’s note: This product is a “universal”, self-sensing LED dimmer (Leading/Trailing Edge). Suitable for conventional light bulbs, halogen light bulbs and most LED light sources. The dimmer is a 2-way device but the second control has to be a “push-to-make” retractive switch.

Product Options

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.

The concept

The blueprint for this classic rotary switch is one of the original Bauhaus switches (which can be found, amongst other places, in the Dessau Bauhaus, renovated true to its original state).

Despite its origins in the 1930s, it has a more restrained and modern look than our Duroplast Rotaries and an altogether smoother feel. A classic switch concept, which endured while fashions came and went.

A stylish return to the roots of classic switch design

The source

Berker’s “1930” series was designed in close consultation with the Architectural Research Department in Dessau. The elegantly simple rotary switches embody the pure functionality to which Berker has been committed ever since its foundation in 1919 – rather like the ethos of the Bauhaus school.

In other words, despite being a modern electrical product, the switches look just as if they had been selected by Walter Gropius himself!

The inspiration

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 matt, monochrome finishes complement a Scandi-style living room just as beautifully as this lavish wallpaper and velvet headboard.

One thing that we always notice in projects that are accessorised with these pieces, is that the round, black or white dots on the walls add an eye-catching detail wherever you decide to use them,
