Operating Instructions

The CAM Limit Switch operates by detecting the physical presence or position of a moving object or cam. When the actuator arm is engaged by the cam, the internal contacts change state (e.g., NO contacts close, NC contacts open).

• Actuation: Ensure the cam or moving part makes consistent and full contact with the switch's actuator arm.
• Reset: The switch will reset to its original state when the cam disengages from the actuator arm.
• Testing: After installation, manually actuate the switch to confirm proper electrical response in the control circuit.

Maintenance

Regular maintenance ensures the longevity and reliable operation of your CAM Limit Switch.

• Inspection: Periodically inspect the switch for physical damage, loose connections, or excessive wear on the actuator arm.
• Cleaning: Keep the switch free from excessive dust, debris, and moisture. Use a dry, soft cloth for cleaning. Do not use harsh chemicals.
• Lubrication: The internal mechanism is typically sealed and requires no lubrication. Do not attempt to lubricate internal components.
• Replacement: If significant wear or damage is observed, replace the switch immediately to prevent system malfunction.
