Switch and control cabinets

As the requirements to be met by modern machines become ever more stringent, and topics such as Industry 4.0, predictive maintenance and extended usability set new standards, manufacturers need to revise, extend and upgrade the electrical systems of their products – while keeping costs low. As a result, the switching and control technology behind their machines becomes more complex, and switch cabinets must record more data than ever before, transmit more sensor signals and control more components.

As the complexity of the machine control increases, a number of aspects such as serviceability, easy replacement and long-term availability of spare parts as well as options for future upgrading must be taken into account for the design of a control cabinet. We have the knowledge, skills and experience to successfully tackle these challenges.


As a specialist supplier, we are able to build switch cabinets of any type and size and for any purpose and machine. We design and manufacture:

  • Terminal boxes and distributors,
  • Switch cabinets,
  • Control cabinets,
  • Operating cabinets and control desks,
  • Low-voltage distribution panels,
  • Network and server cabinets,
  • Frequency converter cabinets,
  • 19" racks,

We offer rubber distributors as well as units made in standard steel, stainless steel and plastic – based on our own design or assembled according to your documentation – in the quality you demand and delivered just in time. We also work as a contract manufacturer and are experienced in the completion of turnkey projects.

Cable assembly

To make it clear from the start: we are not equipped for large series production and do not supply simple cables or low-quality assemblies.

Plants are only productive, if all functional connections are of a high quality and rugged design. Otherwise, operators run the risk of prolonged downtimes and high repair costs, especially if they need to source bespoke cables made in special materials. We produce small series, customised assemblies and special cables that meet stringent requirements in order to withstand heat, water ingress, exposure to chemicals and other adverse ambient conditions.

We produce assemblies of:

  • Flat cables,
  • Multi-wire cables,
  • Single-strand cables.

Our lines are crimpled, press-fitted and fully equipped with manufacturer tags and printed data labels. After production, every cable assembly undergoes a series of stringent tests.

Our cable harnesses are primarily installed in ships, boats and maritime industrial plants. We are known for our top-quality and durable cable harnesses designed for yachts and other boats, as they offer a commercially viable alternative to conventional cable ducts inside the hull. Many renowned shipyards are relying on our expertise and experience in this field.

We gladly assist you in engineering all your electrical systems. Together with you, we choose the most suitable solution. We then draw up the circuit diagrams and wiring layouts, produce the harnesses and finally install them in your vessels. We also support you in commissioning your systems, testing your vessels and making delivery voyages. In addition, we offer comprehensive technical services – worldwide.


Business people know that, in the end, all profit comes from sales. We help you minimise costs through smart and far-sighted engineering at the diagram drawing stage, by choosing the right materials and by devising the interfaces with other systems – on site or at the drawing table. Our experienced engineers and project managers always focus on the needs of our customers and come up with technically advanced switch cabinet and cable harness designs that enable plant manufacturers to deliver on time, commission plants with minimum effort and hand them over with all the required documentation in place.



We use software solutions from various industries to analyse and resolve problems. For our technical designs, we work with the latest versions of:

  • WSCAD Suite
  • EPLAN P8
  • Engineering Base
  • SolidWorks und AutoCAD


In addition, we run programs from all major suppliers for the automated programming of PLCs, frequency converters and similar devices.

Our experience

Sometimes, we face challenges that we cannot successfully tackle on our own. In these cases, we can rely on trusted partners who assist us with their know-how, enabling us to come up with suitable, cost-effective and well thought-through solutions.
