Your strong partner

Trimod’Besta level switches have been manufactured at the Swiss headquarters in Uster since 1966 and are constantly adapted to current market requirements. We are active in a wide range of level measurement technology: From shipbuilding, oil and gas, chemicals and petrochemicals to power generation, plant construction and water management.

Thanks to decades of application experience and high product quality, we have a strong market position and customer acceptance worldwide. Trimod’Besta level switches are used wherever robustness, a long service life and specific approvals from recognised test centres are required and the operating conditions place high demands on the products.

We support our customers competently, quickly and solution-oriented. Our sales partners guarantee on-site professional advice for efficient, application-specific solutions as well as comprehensive after-sales service.


Besta AG was founded in 1966 as a wholly owned subsidiary of Bachofen Holding AG. Besta AG has been integrated into Bachofen AG since October 2015.
