It is also not intended for high-current power switching applications.
Key specifications
Contact configuration: 1NC (Normally Closed) and 1NO (Normally Open)
Actuator type: Rotary lever
Housing material: Durable plastic
Design: Miniature limit switch
How to use
The switch should be mounted securely to a stable surface using the provided mounting points, ensuring the rotary lever is positioned to make contact with the target object at the desired actuation point. Electrical connections should be made to the internal terminals according to the required circuit logic (NC or NO). Ensure that the mechanical travel of the lever does not exceed the physical limits of the switch to prevent damage to the internal mechanism.
What to consider before purchase
Verify the physical dimensions to ensure compatibility with your mounting space.
Check the electrical load requirements of your system against the switch ratings.
Ensure the rotary lever type is appropriate for the mechanical movement of your equipment.
Confirm the environmental conditions of the installation site.
Usage recommendations
Regularly inspect the rotary lever for signs of mechanical wear and ensure that the mounting hardware remains tight to maintain precise actuation accuracy over time.
