The history
Created by Jungย in 1967, the LS990 switch range was inspired byย theย Bauhausย design philosophyย of the 1920s. Drawing on the principle of the unity of practicality and aesthetics, ย the LS990ย incorporated geometric form with simple elegance. It becameย an instant classic, enhancing the ambience of manyย iconic buildings, and is still lovedย by architects, interior designers and homeowners alike.
The LS990ย has been in production for 48 years and is still one of the most recognisable switches you will find.

unpretentious and attractive, reliable and multifunctional
The inspiration
With its clean, square lines and sleek finish the LS990 switch is at home in modern, minimalist interiors as well as more traditional homes, where the innate character needs to be drawn out. It is a timeless, simple switch that will sit visibly on your wall without being attention-seeking. Even surfaces and an effortless modular form offer comfort and style in equal measure, whether you choose it for a clean white space or to contrast with a busier print or pattern.
The basic LS990 ranges offer semi-glossy finishes in monochrome colours for understated interiors, as well as complementing the otherย LS990ย Silver, Luxe orย Dark Metalย ranges, which makes it the perfect companion for a wide range of styles.
