The modular design allows for the combination of 1 to 4 switching elements per button. Protection ratings range from IP40 for protected installation locations to IP69K for high-pressure cleaning. The contacts comply with IEC 60947-5-1 and IEC 60947-5-5. Leading manufacturers such as RAFI are in the range.
Typical areas of application
The 22.5 mm series pushbuttons and switches are suitable for all industrial control tasks. In mechanical engineering, they serve as controls on control panels and mobile handheld controllers. Special machine builders appreciate the wide variety of options for custom solutions. In the automotive industry, the robust switches are used in production lines and test stands. In general plant engineering, they also form the interface between humans and machines – reliably, even under harsh environmental conditions.
