Safety button – reliable protection and control

This red safety button with a nickel-plated ring, designated SP22-B-20, is an element designed for emergency stop of machines and equipment. Its solid construction and high resistance to external conditions (IP65) make it an ideal solution both in demanding industrial conditions and in commercial applications. This button is compatible with 22 mm diameter holes, which simplifies its installation in existing control panels.

Construction and application

The SP22-B-20 button is characterized by a mushroom-shaped design, ensuring easy and intuitive operation. Non-latching (without self-reset) guarantees that after pressing the button remains in the closed position until manually released – a key aspect in emergency situations. Two normally closed contacts ensure reliable circuit interruption in case of danger. The front ring made of gray plastic adds aesthetics and protects against mechanical damage. Screw connection provides a secure and durable electrical connection.
