Protruding green button 2 NC 1 NO nickel-plated ring ST22-WZ-21. ST22-WZ-21\.

Control button – reliability and durability in every circuit

This protruding, green button is designed for mounting in 22 mm diameter holes. It provides convenient and reliable control of devices, and its solid construction guarantees long-term operation even in demanding industrial conditions. The button is used in control panels, machines and equipment where reliable signaling and control are required.

Construction and parameters

The button is characterized by a high degree of protection IP65, which means resistance to dust and water jets. Made of high-quality plastic and equipped with a nickel-plated front ring, it combines durability with an aesthetic appearance. It has two normally closed and one normally open contacts, allowing its use in various electrical applications. Non-latching ensures stable maintenance of the switching state until further intervention.

Solid connections and safety

Screw connection ensures secure and safe connection of wires, minimizing the risk of accidental disconnection. The round shape of the lens and the lack of backlighting make the button readable and easy to use even in low light conditions. Durable materials used in production guarantee resistance to mechanical damage and corrosion.

When designing control circuits, remember the standard hole diameter – 22 mm – ensuring compatibility with most control panels. The high degree of protection IP65 protects against dust and water, making it an ideal solution for industrial environments. The contact configuration of 2NC (normally closed) + 1NO (normally open) offers flexibility in circuit design. The front ring made of plastic is lightweight and corrosion resistant. Non-latching allows maintaining the switching state without continuous pressing.
