Emergency stop button – safety and reliability in any environment

This red mushroom button, with a diameter of 40 mm, is a key element of safety systems in machines and industrial equipment. Designed for immediate shutdown in emergency situations, it ensures a quick response and minimizes the risk of accidents. The construction with a metal front ring guarantees durability and resistance to mechanical damage.

Design and application

The button is designed for mounting in 22.5 mm diameter holes and features a rotary unlocking mechanism.
