About us

Sefag Components AG develops and produces specialised connecting components for electrical systems that ensure trouble-free, long-lasting power transmission. Since 1957, the Sefag name stands for quick, tailor-made solutions to any connection problem.

Whether in tight spaces in mechanical and plant engineering, in motion in automotive engineering or under heavy physical and electrical load in energy distribution – our components and systems come into their own when power has to be transmitted in difficult conditions.

Our customers appreciate the quality of our products, not to mention our flexibility and reliability. They benefit from comprehensive consulting and support, starting with the joint conception and planning of a connecting element. Thanks to a wide range of possibilities in combining various components into individual assemblies, we can find the right solution to any challenge – even under tight schedules.

In addition to engineering, our core skills also include the production of these specialised components, particularly welding and joining technology. We process, coat and connect aluminium, copper and other metals. This is where our decades of experience really pay off. Sefag Components AG thus stands for tailor-made, long-lasting connecting components in outstanding Swiss quality.

Around 50 members of staff are employed at our plant in Malters near Lucerne.
