What Is a Centrifugal Switch?

A centrifugal switch is a critical component in single-phase induction motors. It disconnects the start winding from the power supply once the motor reaches approximately 70–80% of its rated speed, allowing the motor to run efficiently on the main winding alone. A faulty switch can prevent motor startup or cause overheating. Replacing it promptly keeps your motor safe and productive.

Important Notes

• Please allow ±5–10 mm differences due to manual measurement.
• Actual color may vary slightly due to monitor settings and lighting.
• Refer to your motor's documentation to confirm compatibility before ordering.
