Safety button 1 NC nickel-plated ring ST22-B-10. ST22-B-10\.

Safety button – reliable protection and control

This red safety button, manufactured by the renowned company Spamel, is a key element in control systems requiring precision and reliability. Designed for applications where maintaining the state after activation and deliberate unlocking is needed, rather than immediate stopping. It is ideal for machines and devices where the safety signal must be maintained until the operator intervenes.

Construction and parameters

The button actuator is characterized by a solid construction made of high-quality materials. The front ring made of gray plastic and the nickel-plated ring ensure durability and an aesthetic appearance. The button has one normally open contact and is designed for mounting in a 22 mm diameter hole. The IP65 protection class guarantees resistance to dust and strong water jets, making it an ideal solution for working in harsh industrial conditions.

• Button type: Mushroom-shaped, high – provides easy identification and convenient operation.
• Color: Red – standard warning color for safety elements.
• Hole diameter: 22 mm – allows easy integration with most control panels.
• Protection class: IP65 – guarantees resistance to harsh environmental conditions.
• Front ring material: Plastic – provides durability and resistance to mechanical damage.
• Electrical connection: Screw – ensures a secure and reliable connection of wires.
