Passionate about the world of switches

We have been manufacturing high-quality switching devices since 1946. As a family business with over 200 employees, all of our development and production processes are carried out in Germany. Our rotary cam and on-load switches are used across a wide range of industries, from mechanical engineering to renewable energies. Maximum quality, following the highest international standards, and at excellent prices.

>15.000

different active switch types produced each year.

>500 million

safe switching operations enabledper year by our switches.

>35.000

MW of switching capacity provided per year – equivalent to around 6,000 wind turbines.

One site for all solutions

From development and design to assembly, we bring together all our value creation under one roof. This ensures efficient processes and allows us to achieve our most important goal more quickly: to provide you with the best switches in the shortest possible time. Our state-of-the-art production facilities are staffed by a team that combines experience, competence and empathy, and that is personally available to assist you at all times.

These values are important to us

Solutions tailored to your needs

When the market moves, we react quickly and flexibly to changes. As a family business, we initiate new processes in a short amount of time, which allows us to offer our customers the right products for their specific challenges, even if the job only has one switch. The basis for this is our modular switch system.

Service with a human touch

We have a flat organisational structure and few sites. Our team in Schwabach is close-knit, enabling us to provide support to our customers with a human touch. We collaborate closely with customers to identify the best solution, which encompasses consulting, production, and development services. We pride ourselves on our ability to deliver quickly and provide excellent service, including rapid assistance when machines are down.

Value for money

All of our switches are developed and manufactured in our two plants in Germany without the use of intermediate suppliers. We utilise state-of-the-art systems and a well-coordinated team to produce switches of the highest quality at a competitive price.

Quality and safety

Our switches are certified and designed to meet the international switch standards IEC 60947, UL 508, CSA and CCC. In addition, there is a standard only we offer: UL489 for the switch connection directly to the main power line. Prior to delivery, each switch is subjected to an electrical and visual inspection. Our in-house production of all plastic parts ensures consistent quality across the entire switch. Our QM system, certified to 9001 standards, provides comprehensive quality assurance.

Sustainability

By consolidating all our operations in one location, we support the local economy and minimise our ecological footprint. We aim to achieve climate neutrality in all our switch production. For example, we use cardboard packaging that uses 70% less water to produce, run our office paperless, generate solar power, utilise waste heat and employ an energy-saving ventilation system.
