Relays manufactured in Denmark since 1971 – the history of Thiim Relays
Over 50 years of developing and manufacturing relays
Some companies are moving their production elsewhere.
We decided to keep it.
Thiim’s roots date back to 1940, and ever since the company was established in its current form in 1971, relays have been a central part of our DNA. For decades, our solutions have helped to monitor, protect and safeguard critical installations in industry, energy and infrastructure.



A lot has changed since then.
Technology has become more advanced, standards have risen, and the world has become more global.
But one thing remains the same: We still develop and manufacture our relays in Denmark.
From our premises in Søborg, we combine many decades of experience with modern development and production. Every relay is based on technical expertise, craftsmanship and an uncompromising approach to quality.
At a time when so much electronics has become mass-produced goods manufactured far away, it has become something special to be able to say:
Developed and manufactured in Denmark.
It’s not just our history. It’s our identity.
