Innovation with foresight

Passion, inventiveness, flexibility and customer focus have transformed a family-run business of four persons into a global brand with products for professional applications in building automation. Grässlin was founded in St. Georgen in 1956 by Dieter Grässlin and is still to this day regarded as a pioneer in time switch technology. With a clever strategic concept and entrepreneurial vision, he continuously developed the company further. The rapidly expanding company quickly established itself as an internationally respected specialist in the fields of time switch technology, temperature and light control, and tariff switch technology. Various product innovations and a global reputation as a reliable expert in time switch technology underscore Grässlin’s position as a market leader.

Since 2007, Grässlin has been a member of the Intermatic Group, a leading manufacturer of energy control systems with its headquarters in Spring Grove, Illinois, USA. Intermatic employs approximately 750 staff at six international locations. Owing to its globally unique competency in products for the field of time switches as well as light and temperature control, Grässlin makes a crucial contribution to Intermatic as a global specialist in the area of energy management solutions.

We view the satisfaction of our customers, reliability, competence and the focus on common goals and successes as the basis of our daily business. For we can only be successful if we strengthen the success of our customers. 

As an ISO 9001 certified company, we align ourselves with the latest quality standards. This formidable quality awareness, our skilled employees and their strong identification with the corporate group characterise Grässlin along with a flexible organisational structure. We seize our business opportunities responsibly in order to achieve positive results in the long term.
