Red mushroom button 4-pole nickel-plated ring SP22-DC-04. SP22-DC-04\.

Control button red with nickel-plated ring – reliability and protection in one

This red mushroom button SP22-DC-04 is a control element that can be used both in demanding industrial conditions and in building installations. Designed for durability and safety, it is a key component in alarm systems, emergency machine stops and other applications requiring immediate response. Its solid construction and high degree of protection IP65 guarantee trouble-free operation even in difficult environments.

Construction and operating parameters

The button is characterized by a 22 mm diameter hole and is made of high-quality materials. It has four normally open contacts, which allows its use in various control circuits. The self-resetting mechanism ensures immediate release after pressing, which is particularly important in emergency situations. The front ring made of plastic provides additional protection against mechanical damage and ingress of dust and moisture. Screw connection ensures a secure and durable connection of wires.

Application and compliance with standards

The SP22-DC-04 button meets the requirements of PN-EN 60947-5-1 and IEC 60947-5-1 standards, which confirms its compliance with European safety standards. Therefore, it can be used in a wide range of industrial and building applications where high reliability and protection against interference are required. The degree of protection IP65 means resistance to water jet and dust, which allows installation indoors and outdoors (provided additional protection against direct exposure to atmospheric factors). The rated switching current Ie in AC-15 category is 2.5 A (at 230 V voltage), and in DC-13 category – 4 A (at 24 V voltage), which allows controlling various electrical loads.
