Safety button – a reliable element of electrical installation

This red safety button, with a diameter of 22 mm, is a key element ensuring safety in various applications – from machine control and alarm systems to emergency device shutdown. Designed for mounting in 22x22 mm openings, it features a solid construction and a high degree of protection IP65, guaranteeing reliable operation even in harsh industrial conditions. Made of high-quality plastic and equipped with a gray front ring, it looks aesthetically pleasing and is resistant to mechanical damage.

Functionality and technical parameters

This button is a non-latching model, meaning it remains in the closed position after being pressed until released again. Its mushroom-shaped design ensures easy and intuitive operation, and the screw connection allows for quick and secure wiring. It has one normally open (1NO) contact, making it ideal for applications requiring immediate circuit interruption in an emergency. This allows installers to easily integrate it with existing safety systems.

The materials used and the construction provide resistance to vibrations, impacts and atmospheric factors. The button meets the requirements of PN-EN 60947-5-1 and IEC 60947-5-1 standards, confirming its compliance with European safety standards. Connection cables with a cross-section of 1…2.5 mm² (solid wire) or 0.75…1.5 mm² (stranded wire) ensure a stable electrical connection. The minimum force required to reach the effective open position is 28 N. Mechanical durability at the level of 300 thousand switching cycles guarantees long-term and trouble-free use.
