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

Illuminated control button – reliability and functionality in every circuit

This complete control button with a protruding button combines a solid construction, intuitive operation and clear optical signaling. It is ideal for both industrial applications and control panels of various devices. The button has been designed with durability and reliability in mind, which translates into a long service life and minimizes the risk of failure.

Construction and application

The button is designed for mounting in a 22 mm diameter hole. Made of high-quality materials, it provides resistance to harsh working conditions, confirmed by the IP65 protection class – dust and water resistance. Green backlight, powered by 230 V via a BA9S base, guarantees good visibility even in low light conditions. The self-resetting mechanism ensures immediate release after pressing, which is particularly important in applications requiring a quick response. The front ring made of plastic adds aesthetics and protects against accidental damage.

Advantages and benefits

• Versatility: The button has both normally open (1 NO) and normally closed (1 NC) contacts, allowing it to be used in various control circuit configurations.
• Durability: Designed to operate in a wide temperature range (-40°C to +70°C) and resistant to vibrations and shocks, guaranteeing reliable operation even in demanding industrial conditions.
• Safety: Compliance with PN-EN 60947-5-1 and IEC 60947-5-1 standards ensures safe use and compliance with applicable regulations.
• Easy installation: Screw connection facilitates quick and secure connection of wires.
• Clear signaling: Green backlight makes it easier to identify the button and informs about its status.
• Long service life: Mechanical durability of 3 million switching cycles guarantees long-term use without frequent replacement.
• Protection against external factors: The IP65 protection class protects against the influence of dust and water, which increases the reliability of the device in difficult environmental conditions.

Technical parameters – key information for the installer

Rated continuous current at 10 A and rated switching currents (2.5 A AC-15 at 230 V and 4 A DC-13 at 24 V) allow the use of this button in circuits with different loads. Short-circuit protection of the switching elements (10 A with a fuse insert) further increases the safety of the installation. The cross-section of the connection wires is 1…2.5 mm² (solid) or 0.75…1.5 mm² (stranded). Remember to select appropriate overcurrent protection in accordance with the standards in force in a given country.
