KELLER PRESSURE: Leading manufacturer in the production of isolated pressure sensors and pressure transducers
February 16, 2026 / 1:45 PM
KELLER Pressure was founded in 1974 by Hannes W. Keller, inventor of the integrated silicon chip. Today, his two sons Tobias and Michael Keller are responsible for the company. The company is wholly family-owned and employs approximately 500 people from more than 20 countries. It will also be presenting its stand at the AMPER 2026 trade fair.
Production
All production takes place at the company's headquarters in Switzerland, where most of the employees also work. All products bear the "SWISS MADE" seal of quality, which is associated worldwide with expertise, quality, tradition, and a realistic approach.
The advantages of KELLER PRESSURE products are primarily their great variability (according to customer wishes and requirements) and their renowned high Swiss quality and precision.
Here is a quote from Technical Director Bernhard Vetterli:
"Our technological knowledge, many years of experience, and mastery of numerous pressure sensor manufacturing processes, combined with a high level of workmanship, enable us to make the impossible possible." Bernhard Vetterli, Technical Director, KELLER Pressure
The future
A new headquarters building is currently under construction in Winterthur, to which the entire production will move in 2026. KELLER PRESSURE is committed to Switzerland as its place of business and will continue to focus on "SWISS MADE" in the future.
