Switch head with key – reliability and safety in your installation

This Ronis 455 switch head from the Harmony XB4 series is a robust solution for industrial applications where access control and protection against unauthorized operation are required. Designed for mounting in 30.5 mm diameter holes, it provides reliable and durable operation in demanding conditions.

Design and application

The switch head is designed to work in control systems where a physical lock of the switch position is needed. Thanks to its two switching positions and non-latching function, it is ideal for applications requiring maintaining a specific circuit state. The key provides additional security against accidental changes or unauthorized access. Made of high-quality materials, including a metal front ring, it guarantees long-term reliability even in harsh industrial conditions.

Protection and durability

The construction of the switch head provides a high degree of environmental protection. The IP66 protection class protects against dust and water jets under pressure, making it ideal for outdoor or humid environments. Additionally, it meets the NEMA 13 standard, confirming its resistance to external factors. The chrome-plated front ring not only adds aesthetics but also increases corrosion resistance. The black control element ensures good visibility and easy identification.
