Top-quality products with experience of over five decades

Kari-Finn Oy developed its first float switch back in 1965. Since then, we have designed, tested, and manufactured millions of float switches, for a wide variety of operating environments. Thanks to our research work and feedback from customers, we have been very successful in developing our product line.

The KARI float switch was awarded a gold medal at the Brussels International Exhibition of Invention and a medal of the City of Brussels for an extensively exported product already in 1977. At that time, exports covered all countries in Europe, the United States, South Africa, and Japan. Later on, exports reached every continent.
