Spamel ST22-KLZ-11-230-LEDAC 22mm Green Illuminated Push Button with 1NO 1NC Contacts and Spring Return

The Spamel ST22-KLZ-11-230-LEDAC is a high-quality 22mm green illuminated push button engineered for demanding industrial control environments. This robust control component features a reliable spring-return mechanism, ensuring the button returns to its original position immediately after release. Equipped with both 1NO (Normally Open) and 1NC (Normally Closed) contact blocks, it offers versatile switching capabilities for various electrical control circuits. The integrated LED light provides clear visual status indication, which is essential for monitoring machine operations and system states in real-time.

Advantages

This push button stands out due to its durable construction and precise mechanical performance, which are critical for maintaining consistent operation in industrial settings. The inclusion of an integrated LED light simplifies the design of control panels by eliminating the need for separate indicator lamps, thereby saving space and reducing installation complexity. Its standard 22mm mounting diameter ensures compatibility with a wide range of existing enclosures and control panels, while the combination of 1NO and 1NC contacts provides the flexibility required for complex automation logic and safety interlocks.

Suitable for

• Industrial control panels and machinery operation
• Automation systems and process control
• Electrical control circuits requiring visual status feedback
• Emergency stop or start-stop control sequences

This push button may not be suitable for environments with extreme chemical exposure or high-pressure washdown requirements unless housed in an appropriately rated protective enclosure. It is also not intended for high-power switching applications that exceed the rated electrical capacity of the internal contact blocks.

Key specifications

• Mounting diameter: 22mm
• Button color: Green
• Contact configuration: 1NO and 1NC
• Operation type: Spring return
• Illumination: Integrated LED
• Voltage: 230V

To install the device, insert the push button unit into a standard 22mm hole on the control panel and secure it firmly using the provided locking nut. Connect the electrical wires to the designated 1NO and 1NC terminals according to your circuit diagram. Ensure that the power supply matches the 230V rating of the integrated LED to prevent damage and ensure proper illumination.

What to consider before purchase

• Verify that the 22mm mounting hole size is compatible with your existing panel.
• Ensure the 230V LED voltage matches your control circuit power supply.
• Confirm that the 1NO and 1NC contact configuration meets your specific switching requirements.

For optimal longevity and reliable performance, ensure that all electrical connections are tightened securely and that the device is protected from excessive dust, moisture, or vibration that could impact the mechanical spring-return mechanism.
