Yesterday and today

The success story of BROSA can be described in one sentence: continuous development with the aim of meeting customer needs with perfection. Erich Brosa was already operating according to this principle in 1935 when he started developing and producing electric transducers in Berlin. Later, Erich Brosa became self-employed in Freiburg and moved operations to the current headquarters in Tettnang/Bodensee in 1956. At that time, BROSA produced mainly pressure and acceleration sensors for large-scale regional enterprises. Dr. Bernd Brosa, the son of the founder, expanded the business field with the acquisition of an electronics company in Rüthi / Switzerland in 1974. As part of a succession plan, the 32-employee-strong company of two family businesses was acquired in 2000, which to this day continues its business as a mid-sized technology leader.

In 2003, the old factory buildings were demolished and a new 2,500 square meter production facility was built, and the Swiss site was completely modernized and expanded. With the establishment of new sales companies in 2004, new markets have been opened up. BROSA Singapore focuses on the Asian market, BROSA BV in Holland on the offshore market. Due to the great success in terms of new innovative products, the location was no longer big enough.

In 2007, 17,000 square meters of land were acquired in the Bürgermoos industrial area. Since 2008, there has been a new administration and production building with 6,000 square meters.

To expand into new markets, BROSA established a sales company in China in 2018: BROSA (Nanjing) Co., Ltd .

In 2021, BROSA acquired Rüthi Electronic AG, which will strengthen the BROSA Group as a center of excellence for electronics, especially hardware and software development. The BROSA Group thus grows to well over 100 employees.
In the same year, IBR Industriebeteiligungen Ravensburg mbH further expands its majority shareholding in BROSA and is now the sole shareholder.
At the beginning of 2022, BROSA is launched in a new legal form, BROSA AG becomes BROSA GmbH and in july the Rüthi Electronic AG to BROSAtronic AG, for our customers everything remains the same and the success story continues.
