LS – a true classic

A true classic is a product from another era that effortlessly outlasts every trend. With ease and only minimal changes, it adapts to new circumstances and challenges. A genuine classic sets standards for decades. It is universal and timeless.

DORNBRACHT x JUNG: One finish. Two brands. 

One shared finish for switches and fittings. With a new cooperation, DORNBRACHT and JUNG combine their design expertise under the motto “Signature Design. Crafted in Finishes”. From May 2026, both manufacturers will offer a shared finish – enabling a consistent design across architecture and interiors.
LS 990 in Bronze brushed 
A first in interior design: with the real metal finish in a copper tone, DORNBRACHT and JUNG offer a shared finish. For JUNG, LS Bronze is a new variant within the LS design range; for DORNBRACHT, the finish corresponds in name, colour and feel to the established Bronze brushed version. The result is an authentic, brand-spanning identical finish for switches and fittings.
With LS TOUCH, JUNG expands the range with a smart room controller for KNX single-room control. 

The high-resolution touch display combines operation and visualisation. Control is via swipe gestures, following the logic of modern smartphones. The display colour is coordinated with the respective frame finish. Also available worldwide exclusively in the 63 colours of Les Couleurs® Le Corbusier®. Integrated in LS 990 and flush-mounted in LS ZERO.

50 years of LS 990 

Half a century after its introduction, the switch classic continues to impress with its timeless elegance. A reduced form, flat surfaces and a clear design define its identity. At the same time, the system has evolved dynamically in technical and functional terms in recent years.
LS 1912 – the aesthetics of switching 

Since 1912, JUNG has combined purist design with innovative strength. With the LS 1912 toggle push-button, we continue this tradition and reinterpret it for the present day. Material and mechanics give the LS 1912 switch a very special charm. The toggle levers in Aluminium, Stainless Steel, Brass or Chrome make the mechanics of switching tangible once again.

Forty years after its introduction, the LS 990 continues to stand for the clear square of Bauhaus. 

With a 70 × 70 mm rocker and an 81 × 81 mm frame, the system is based on a consistently modular principle. The reduced form still enables system-compatible further developments today.
With the KNX push-button FD 990, JUNG shapes intelligent building technology. 

The clear lines and high-quality materials such as Aluminium or Stainless Steel give the LS system a particularly light, understated presence in the room.

The range consistently continues the proven JUNG operating philosophy. High flexibility is ensured by the practical modular design as well as the simple adaptation of the devices to changing requirements. The push-buttons enable control of KNX/EIB with full functionality as well as radio management – particularly interesting for retrofitting – and the control of systems with 24 V extra-low voltage.
In this year, the LS 990 receives a high-gloss electroplated metal version with Chrome. 

The reflective surface gives the clear square a distinctive radiance and deliberately turns the switch into a design element – while the system’s range of functions remains unchanged.

The LS 990 is now also available with protection rating IP44 and is therefore suitable for damp rooms. 

The clear, reduced design remains unchanged. This creates a consistent design language across all rooms – in line with the LS system concept.

LS 990 with protection rating IP44

In 2004, JUNG expands the LS 990 range with an architecturally consistent solution: by using the sealing flange 551 WU, protection rating IP44 is achieved – making it suitable for use in bathrooms and covered outdoor areas. What matters here is not only the technical function, but also the continuity of the design.
JUNG presents a room controller from the EIB (KNX) system in the design of the LS 990. 

The operating device combines functions such as lighting, blind and temperature control in a single unit. This made the switch classic an interface for intelligent building technology at an early stage.
Room controller
With the room controller in 2003, JUNG introduced its first solution for individual room control based on EIB (today KNX) – setting an important impulse for building automation in large-scale projects. The combination of temperature, lighting and shading control in a single device convinced planners and investors alike. From a design perspective, the integration of the display between the buttons was a particular achievement. It combined technical functionality with a clear architectural design language and made the room controller especially popular with building owners and architects.
For the Federal Ministry of Labour and Social Affairs in Berlin, JUNG develops the LS 990 in the real metal version Aluminium together with Prof. P. Kleihues. 

The precise metal surface underlines the architectural ambition and consistently transfers the classic into high-quality project applications.
LS 990 Aluminium
The particular challenge of the real metal version “Aluminium” lies in the different manufacturing processes: while the frames are deep-drawn, the covers are precisely folded. This constructive difference is also a deliberate homage to the authenticity and materiality of the metal. JUNG is the first switch manufacturer to achieve this implementation in aluminium. In doing so, the company underlines its technological expertise and its leading position as a specialist in metal processing.
For the Reichstag in Berlin, JUNG develops the Light Grey version of the LS 990 at the request of the architecture office Foster + Partners. 

The subtle colour tone integrates into the overall architectural concept and documents the project-related further development of the classic.

For the project ensemble “Office Building Cubes” and the “INNSIDE by Meliá Hotel Düsseldorf Seestern”, LS 990 is produced in the Black version at the request of the architects Michael Schumacher and Tim Schneider and later added to the standard product range.
With the Gold-Bronze finish, the LS 990 receives another metal variant. 

The warm metallic tone reflects the design spirit of the late 1980s and strengthens the position of the switch as a deliberately used element in high-quality interiors.
LS 990 Gold-Bronze
With Marble White, JUNG expands the LS 990 range with a decorative finish featuring a marble-like appearance. 

The lively, natural-stone-like structure reflects design trends of the 1980s and positions the switch more strongly as a consciously chosen interior element.
LS 990 Marble White
With Alpine White, the LS 990 receives a clear, light colour tone as a deliberate contrast to the previously dominant brown and warm shades. 

The new colour represents a design shift towards lighter, more reduced spatial concepts of the 1980s.
LS 990 White
JUNG consistently transfers the selected materials to the frames and inserts of the LS 990. 

Form and surface now create a continuous unity. With a total of six available finishes, the range gains in design precision and its ability to integrate into the architectural context.
LS 990 Brown leather-grain
In keeping with the taste of the time, the switch was available for several years in various shades of brown, including a leather-grain version.
With black leather-grain rockers, JUNG expands the design spectrum of the LS 990 with a striking dark variant. 

The textured surface creates a distinct accent – still without colour synchronisation between frames and rockers.
LS 990 with black leather-grain rocker
With brown leather-grain frames and Brown Antique inserts, JUNG responds to the architectural changes of the 1970s. 

Warm, textured surfaces now shape many interiors. The LS 990 adopts this material aesthetic and becomes a design element within the room concept.
LS 990 cover frame Brown
Adaptation of the LS 990 frame design: 

The edge radius of the originally designed frame of the LS 990 switch system was 1 mm. In 1975 it was changed to 2 mm. The background to this adjustment was the consideration of the statutory accident prevention regulations, especially for insertion in schools.
The thickness of the rounding has reduced the risk of injury at the frame edges and ensured that the switch range meets the increased safety requirements in public facilities without significantly changing the clear design language of the LS 990.
A consistent system logic emerges: 

Functional inserts can be used and combined across different designs. For planning, this means functional continuity alongside design differentiation. The LS 990 becomes part of a consistent technical foundation for different architectural expressions.
System logic
With the expansion of the modular principle in 1973, the LS system was extended to additional switch ranges.
The modular LS system is expanded with hinged covers. 

Additional functions such as room temperature controllers, special devices, antenna covers and SCHUKO® sockets can now be integrated into the uniform system architecture – while the formal clarity of the LS 990 remains unchanged.
LS 990 with hinged cover
The LS 990 is launched as a flat switch in Duroplast White. 

Its clear square geometry, almost graphic appearance and the absence of ornamentation correspond to the formal discipline of the late 1960s. The switch presents itself as an architectural detail – not as decoration.
LS 990 White
At the end of the 1960s, German architecture undergoes a material-related paradigm shift. 

The transition from post-war modernism to late modernism visibly changes construction, surface and expression – an attitude that shapes the design context for the development of the LS 990.
The LS90 word and figurative mark 
was registered on 29 April 1967.

JUNG therefore developed the first LS finishes for upscale residential interiors in silver- and gold-anodised metal. The necessary tools could be produced in the company’s own factory. The white plastic version followed afterwards.
The patent application for the modular LS system
On 30 June 1967, the patent for the construction of the modular LS system was filed – a step that is now regarded as a milestone in switch architecture. At the time of the application, however, the significance of this design principle was not yet foreseeable. The idea of a clearly structured, modular construction created the basis for a system architecture that combines design freedom with technical precision. The underlying construction principle enables the consistent separation of function and design. This approach increases planning flexibility and ensures long-term system continuity. 

For architects, this principle means above all one thing: reliability in design. The modular LS system stands for dimensional accuracy, reduction and a formally clear design language that can be integrated into a wide range of architectural contexts – from listed heritage buildings to contemporary new constructions. What began in 1967 as a structural innovation developed into a lasting system concept. The patent application therefore marks not only the origin of a technical solution, but also the beginning of an architectural continuity that continues to this day.
With the JOT system, introduced in 1965, the idea of a consistently modular principle matures. 

The system is based on human proportions and a clear dimensional grid. Structurally, it develops the technically feasible further and thus lays the foundation for the later development of the LS 990.
Design sketch
This resulted in the outer dimension of 81 × 81 mm, the rocker dimension of 70 × 70 mm and the frame height of 11 mm. This geometric achievement makes it possible to dispense with centre bars in the frame when combining units. The timeless modularity of the LS range was born.
