How to use

To install the Spamel LK211, mount the switch securely to a stable surface using the provided mounting points, ensuring the plunger is aligned correctly with the moving part of the machine. Connect the electrical wires to the 1NO and 1NC terminals according to your control circuit diagram. Verify that the plunger is depressed or released as intended by the mechanical movement of the equipment to trigger the desired electrical state change.

What to consider before purchase

• Verify the mechanical travel distance required for your specific application.
• Ensure the electrical ratings match your control circuit voltage and current requirements.
• Check the environmental conditions to ensure the plastic housing is appropriate for the installation site.

Usage recommendations

Regularly inspect the plunger for signs of wear and ensure that the mounting remains tight to maintain precise switching accuracy over time.
