Safety button 5 NC nickel-plated ring SP22-B-50. SP22-B-50\.

Safety button – reliability and protection in every circuit

This red safety button with a nickel-plated ring, designated SP22-B-50, is designed for emergency shutdown of devices and electrical circuits. Designed for durability and reliability, it finds application both in industry and in home installations where a quick response is required in hazardous situations. Its solid construction and high degree of protection (IP65) guarantee trouble-free operation even in harsh environmental conditions.

Construction and characteristic features

The SP22-B-50 button is characterized by a mushroom-shaped design, which makes it easy to operate even with gloves. Made of high-quality materials, it ensures long-term operation. The front ring made of gray plastic and the overall nickel finish give it an aesthetic appearance and corrosion resistance. Mounting is done in a standard 22 mm diameter hole. An important aspect is the lack of self-return – after pressing, the button remains in the closed position until manually released. This is crucial for ensuring safety, as the shutdown occurs only after conscious intervention by the operator.

• Durable construction: Ensures long-lasting and trouble-free operation even in demanding industrial conditions.
• High degree of protection IP65: Protects against dust and water, allowing installation in various environments.
• Intuitive operation: Mushroom shape makes it easy to quickly and reliably press even in emergency situations.
• No self-return: Guarantees maintaining the off state until the button is manually released – increased safety.
• Universal application: Suitable for mounting in control cabinets, operator panels and other devices requiring emergency shutdown.
• Five normally closed contacts: Allows connection to various control and protection circuits.

Application

This button has 5 normally closed contacts, making it an ideal solution for applications requiring reliable circuit interruption. The electrical connection is made using screw connections, which ensures a stable and secure connection of the wires. The button is designed to operate in circuits with a voltage of up to 2.5 A. Thanks to this, it finds wide application in industrial machines and equipment, automation systems and everywhere where the safety of the operator and protection of equipment against damage caused by failures or malfunctions are a priority. Mounting is done through a standard hole with dimensions of 22 mm x 22 mm.
