Double-button switch 1 NO 1 NC white-black AC SP22-2KL-11-LEDUNI\B/CZ

Double-key control button – reliability and functionality in every application

This complete, illuminated SP22-2KL control button is a robust solution for a wide range of industrial and automation applications. Designed for both professional installers and end-users, it combines durability, safety, and ease of installation. This button is ideal for control panels, machines, and devices requiring reliable on/off switching of circuits.

Construction and operating parameters

The button has a 22 mm mounting hole diameter and offers two control positions. The high-quality plastic front ring provides resistance to mechanical damage and external factors. The IP65 protection degree guarantees protection against dust and water jets, making it suitable for operation in harsh industrial conditions. The round lens shape ensures good visibility of the button status.

The button is characterized by high mechanical durability – it withstands up to 3 million switching cycles, and its switching durability is 0.2 million cycles at rated voltages and currents. It can operate in a wide range of ambient temperatures, from -40°C to +70°C, allowing its use in various climates. It complies with PN-EN 60947-5-1 and IEC 60947-5-1 and IEC 60947-1 standards, confirming its compliance with European safety standards.

Safety and efficiency

The button has been designed with user safety in mind. It has short-circuit protection of the switching element (10 A with a fast-blow fuse) and resistance to vibrations and shocks (according to IEC standards). Connection cables with a cross-section of 1…2.5 mm² (solid core) or 0.75…1.5 mm² (stranded) ensure a solid electrical connection. Thanks to the possibility of choosing different light sources (LED AC/DC, LED-UNI), the brightness of the backlight can be adjusted to individual needs. The lamp power is from 1 W (LED) to 2 W (bulb), and also 1.6 W for LED UNI.
