Flush-mount red button 3 NO/NC nickel ring ST22-KC-30. ST22-KC-30\.

Control button – reliability and durability in every application

This red control button, designed for mounting in a 22 mm diameter hole, is a solid solution for a wide range of industrial and automation applications. Made of high-quality materials, it ensures long-lasting and trouble-free operation even in harsh conditions. The construction with three normally closed contacts allows for flexible configuration of control circuits.

Construction and functionality

The button features a flat design with a red covered button and a nickel-plated front ring, providing an aesthetic appearance and corrosion resistance. A durable plastic front ring further protects against mechanical damage. The self-resetting mechanism guarantees an immediate return to the initial position after the button is released, which is crucial in applications requiring a quick response. Screw connection ensures a secure and durable connection of wires.

Application and parameters

The button is designed to operate in a wide temperature range (from -40°C to +70°C) and features a high degree of protection IP65, which means resistance to dust and water jets. This makes it ideal for use indoors and outdoors. Suitable for wires with a cross-section from 0.75 mm² to 2.5 mm², it offers flexibility in cable selection. It complies with PN-EN 60947-5-1 and IEC 60947-5-1 standards, guaranteeing safety and compliance with applicable standards. The continuous rated current Iu is 10A, and the rated switching current in AC-15 category is 2.5A (at 230V). The mechanical durability reaches as much as 3 million switching cycles, confirming its reliability in heavily used applications.
