JUNG · Schalksmühle, Germany · founded in 1912

The history of JUNG.

“Fortschritt als Tradition” — “Progress as tradition”, the company motto.

JUNG is a family company from the town of Schalksmühle, Germany, led by three generations of one family: founder Albrecht Jung, his son Siegfried, who headed the company from the early 1960s, and his grandson Harald, who has led it since 1993.

Founding · 1912

The first product — a switch with a one-eighth turn.

Albrecht Jung worked as a master craftsman in Schalksmühle, but his ideas met no support there. He rented several cellar rooms and produced his first product: a pull-cord switch with a one-eighth turn, for which he immediately filed a patent application. The especially short actuation path of that mechanism still underlies every JUNG switch today.

Timeline

Three family generations and two plants in Germany.

JUNG’s first own factory building is completed (1927/28).

A second plant opens in Lünen; both remain in Germany to this day.

1968

The LS 990 range is launched; its form has remained unchanged ever since.

1990

JUNG co-founds the EIBA association, which creates the EIB bus, the predecessor of KNX.

1999

The first LS 990 in stainless steel is made for the Office of the German Federal President; JUNG becomes a founding member of the KNX Association.

LS 990 · 1968

A 70 × 70 mm rocker and a five-millimetre frame.

JUNG set out to create a flat switch instead of the usual levers. Graphic artist Herbert W. Richter reduced the form to a square without decorative elements, in the Bauhaus spirit. The proportions were calculated from the dimensions: a maximum inner dimension of 71 mm and a cover of 81 mm yielded a 70 × 70 mm rocker with a frame 5 mm wide all around. Since 1968 the LS 990 has been produced in virtually unchanged form.

Le Corbusier compiled his Architectural Polychromy in two stages: 43 colours in 1931 and a further 20 in 1959. Any of the 63 shades combines with any other. Since 2014 JUNG has been the world’s only manufacturer of switches, sockets and controls in all 63 original colours: each item is made to order, hand-lacquered in Germany and approved by the licensor, Les Couleurs Suisse AG.

Production · Schalksmühle and Lünen

In-house production above industry standards.

All JUNG products are developed and manufactured at the company’s two own plants in Germany. The standard certifies a switch after 40,000 operations, whereas JUNG’s internal specification requires 50,000. The norm for a socket is 10,000 plug cycles; JUNG sockets are rated for more than twice that number. JUNG was the first manufacturer in North Rhine-Westphalia to receive TÜV NORD’s “Made in Germany” certificate.

Building automation · KNX

Helping to create the KNX standard since 1990.

In 1990 JUNG, together with Berker, Gira, Merten and Siemens, founded the EIBA association, which created the EIB bus, the direct predecessor of KNX. In 1999 the company became one of the founding members of the KNX Association. KNX has been the world standard for building automation for more than thirty years, and the LS TOUCH controller manages up to 32 KNX functions in the classic LS 990 frame, including the 63 Le Corbusier colours.
