70 Years of Grässlin: Experience Shaping the Future
Seven decades of technical expertise, reliability and innovation “Made in Germany”
In 2026, Grässlin Zeitschalttechnik GmbH celebrates its 70th anniversary. This milestone represents far more than a long company history: it reflects seven decades of experience in developing reliable solutions for the time-based control of electrical applications.
For 70 years, Grässlin has combined technical expertise with a clear understanding of market requirements. Today, this experience provides the foundation for solutions used in modern building automation, industrial applications and forward-looking smart building concepts.
Long-standing experience as the basis for modern solutions
The requirements placed on electrical control and automation solutions have changed fundamentally over the past decades. Buildings and industrial systems are becoming increasingly connected, processes need to be more energy-efficient, and systems must be adaptable to different usage scenarios.
For technical buyers, design engineers, installers and electricians, this means that components must not only integrate reliably into existing systems. They must also meet growing expectations in terms of functionality, ease of use and future readiness.
Grässlin draws on seven decades of experience to translate these requirements into practical solutions. The result is a portfolio of products and concepts that combines proven technical principles with the possibilities of modern automation.
Technical expertise for a wide range of applications
Time-based controls play an important role in many applications. They help switch electrical loads according to demand, coordinate operating times and implement automated processes reliably.
Applications range from traditional building technology and commercial electrical installations to industrial systems. Precise time-based control also remains an essential element of modern smart building solutions.
Requirements vary considerably from one project to another. Design engineers need technically suitable components for their system planning. Buyers focus on quality, availability and cost-effective procurement. Installers and electricians expect solutions that can be installed, configured and operated efficiently. Electrical wholesalers, in turn, depend on a market-oriented product range and reliable supplier relationships.
Grässlin’s many years of market and application experience provide the foundation for bringing these different perspectives together.
Tailored solutions instead of rigid standards
Reliability is essential in building automation and industrial applications. Switching operations and automated processes must be carried out precisely and consistently over the long term. Failures can disrupt operations, increase service requirements and lead to avoidable costs.
For 70 years, reliability has therefore been a central part of Grässlin’s identity. It is reflected both in the technical design of its solutions and in its long-term cooperation with customers and partners.
For professional users in particular, this consistency offers significant added value. Technical buyers require dependable products and supplier relationships that support long-term planning. Design engineers need to rely on clearly defined technical specifications. Installers and electricians expect components that perform reliably in day-to-day operation.

“Made in Germany” as a commitment to quality
The 70th anniversary also represents technical expertise “Made in Germany”. For Grässlin, this means combining quality, precision and innovation on a lasting basis.
Origin alone is not the decisive factor. What matters is the approach behind development and manufacturing: carefully analysing technical requirements, designing practical solutions and consistently focusing products on their intended applications.
This commitment to quality forms the basis for long-term, collaborative relationships with industrial companies, planners, electrical contractors and electrical wholesalers.
Using experience to shape the future of automation
For Grässlin, 70 years of company history are not only an opportunity to look back on past achievements. They are above all a starting point for continued development.
Building automation, industrial control systems and smart building applications will continue to evolve dynamically. Digitalisation, connectivity and the growing focus on efficient operations are creating new requirements for products and systems.
Grässlin is responding to these developments with seven decades of experience and a clear commitment to continuing to develop reliable, innovative and application-oriented solutions. In this way, long-standing tradition becomes a tangible advantage for modern projects.
70 years of Grässlin stand for technical expertise, reliability and innovation — yesterday, today and in the future.
