Foundation
Kraus & Naimer was founded in 1907, the first workshop being set up in the basement of the building in Wattgasse 53, Vienna. Electricity had just started to conquer the world, but switchgear as we know it today did not yet exist.
Lorenz Naimer, the founder and financier, and his partner Franz Kraus, enthusiastically launched the experiment to manufacture special electrical devices.

By the early thirties, Kraus & Naimer had grown to 50 employees. In 1945, during the last days of World War II, the factory took a bomb hit in an air-raid and was heavily damaged. Mrs. Kraus perished in the shelter of the house.
Hubert Laurenz Naimer – The Pioneer
In 1946, Hubert Laurenz Naimer returned from war captivity to Vienna. A year later, after the death of his father, he had to quit his university studies in Graz to concentrate fully on rebuilding the company.
Thanks to his extraordinary abilities, the first modular cam switch was introduced shortly after and a global production and distribution network set up. After 57 years of hard and successful work, he passed away at the age of 82 on September 12, 2004.
Technical Innovation – Our Recipe for Success
Kraus & Naimer has pioneered many new developments. By the end of the twenties, we had already started to use the new material "Bakelite". The new "Bakelite switch" became known and accepted in the industry.
Modern tooling machines were bought in difficult economic and political situations.
The first modularly designed cam switch was introduced as early as 1949 and revolutionized switchgear technology, its characteristics influencing all subsequent designs.
Over the years, Kraus & Naimer has evolved as the undisputed market leader for cam switches and has established the standards for switch disconnectors. Based on numerous patents, the existing product line encompasses the global market place and offers technically and economically optimized solutions for virtually every application imaginable.
