Safety button – reliability and protection in every circuit

This red safety button with a nickel-plated ring, designated SP22-B-12, is designed for emergency shutdown of devices and electrical circuits. Its robust construction and high IP65 protection rating make it ideal for use in harsh industrial environments as well as building installations. This button is compatible with a 22 mm diameter hole, ensuring easy mounting in standard control panels and machine enclosures.

Construction and functionality

The SP22-B-12 button features a mushroom-shaped design that makes it easy to operate even with gloves on. Made of durable materials, both the button and the front ring (grey, made of plastic) guarantee long-lasting reliability. The non-latching mechanism ensures a secure and permanent circuit disconnection after pressing. Thanks to the screw connection, installation is simple and safe.

• Durability: Made of high-quality materials resistant to mechanical damage and environmental conditions.
• Safety: The non-latching mechanism guarantees maintaining the off state until manual power restoration.
• Versatility: Designed for circuits up to 2.5 A, making it a universal solution for many applications.
• Protection: IP65 protection rating protects against dust and water jets – ideal for workshops and production halls.
• Easy installation: Standard 22 mm hole diameter facilitates integration with existing control panels.

The SP22-B-12 button has two normally open (NO) contacts and one normally closed (NC) contact, allowing for flexible use in various control systems. The round lens shape and nickel-plated front ring add aesthetics and a professional look. The hole height is 22 mm and the width is also 22 mm, ensuring compatibility with most standard control panels. The non-latching design and high resistance to external factors (IP65) make it a reliable element of safety systems.
