Protruding button, illuminated yellow, 1 NO/1 NC, nickel-plated ring ST22-WLG-11-230-BA9S. ST22-WLG-11-230-BA9S\.

Control button with backlight – reliability and functionality in every circuit

This complete control button with a protruding button, backlit in yellow, is a solid solution for applications in industry, machines and equipment. Designed for durability and ease of installation, it is ideal for both new installations and modernizations. Made of high-quality materials, it ensures reliable operation even in harsh conditions.

The button is characterized by an IP65 protection class, which guarantees resistance to dust and moisture – crucial in industrial environments. Backlighting makes it easier to identify and operate in low light conditions. Equipped with screw connection, it provides a secure and stable connection of wires. The construction with a nickel-plated front ring adds aesthetics and protects against mechanical damage.

Construction and operating parameters

The button has one normally open (NO) contact and one normally closed (NC) contact, making it a versatile element in control systems. Its self-resetting design ensures immediate reset after the button is released. Designed for mounting in 22 mm diameter holes, it fits standard panel cutouts. The power supply voltage of the light source is 230 V, and the lamp cap is BA9S – a popular solution ensuring easy replacement of the light source.

• Durability: Adapted to work in a wide temperature range (from -40°C to +70°C) and resistant to vibrations and shocks, as confirmed by compliance with IEC 60068-2-6 and IEC 60068-2-27 standards.
• Safety: Protected against short circuits with a 10A (fast) fuse insert.
• Durability: Ensures long-term operation – mechanical durability is 3 million switching cycles, and switching durability is 0.2 million cycles at rated voltages and currents.
• Application: Ideal for controlling motors, lighting, heating devices and other electrical circuits requiring a reliable switch.
• Compliance with standards: Meets the requirements of PN-EN 60947-5-1 and IEC 60947-5-1 and IEC 60947-1, which guarantees safety of use and compatibility with other elements of the electrical installation.
