For almost 60 years, Sefag has stood for Swiss quality in electrical engineering. Founded in 1957 as a branch of the German PFISTERER Group, Sefag settled in Malters in 1958 in what was then an up-and-coming industrial centre just outside Lucerne.

While production back then relied on used machinery and a great deal of inventiveness, the company has now become a modern manufacturing and service company working to the highest standards – both for its customers and staff.
