Position Switches and Safety Switches

The scope of application for limit switches has changed over time. Whereas limit switches were previously used for thepurpose of detecting end positions, today they are increasingly assuming functions designed to protect persons and products in machine, equipment and plant construction. The BERNSTEIN Safety switch range delivers the perfect solution for virtually any industry.
