Protruding illuminated blue button 1 NO 1 NC nickel-plated ring ST22-WLN-11-230-BA9S. ST22-WLN-11-230-BA9S\.

Illuminated control button – reliability and functionality in one

This complete control button, equipped with a blue illuminated LED, combines durability, safety and ease of use. It is ideal for both industrial applications and control devices where clear visual signaling and reliable operation are required. The construction with a nickel-plated ring provides an aesthetic appearance and resistance to mechanical damage.

Construction and technical parameters

The button is characterized by high quality workmanship and a well-thought-out design. A mounting hole with a diameter of 22 mm ensures compatibility with most standard control panels. The IP65 protection class guarantees resistance to dust and water ingress, allowing safe use in harsh environmental conditions. Screw electrical connection provides a stable and reliable connection of wires.

The button has one normally open (NO) and one normally closed (NC) contact, allowing it to be used in various control circuits. The 230 V powered backlight ensures good visibility even in low light conditions, and the BA9S lamp socket makes it easy to replace the light source. The self-return characteristic means that the button returns to its initial position when released.

• Durability: Designed to operate at temperatures from -40°C to +70°C, resistant to vibrations and mechanical shocks (according to IEC 60068-2-6 and IEC 60068-2-27 standards).
• Safety: Compliant with PN-EN 60947-5-1 and IEC 60947-5-1 and IEC 60947-1 standards, ensuring safe operation.
• Versatility: Possibility of using wires with a cross-section from 1 mm² to 2.5 mm² (solid) or from 0.75 mm² to 1.5 mm² (stranded).
• Durability: Mechanical durability at the level of 3 million switching cycles guarantees long-term use without frequent replacement.
• Signaling: 1W LED backlight provides clear signaling of the device status.

Applications

The button finds application in a wide range of applications:

• Industrial automation: Control of machines and production equipment.
• Control panels: Installation in control panels of various devices.
• Electrical devices: Use as a control element in various types of electrical devices.
• Construction: Control of lighting, gates and other building installations.
• Agricultural machinery: Control of functions of agricultural machines.

Thanks to its versatility and reliability, this button is an ideal solution for both professional installers and end users looking for a solid and functional control element.
