Century Motors 629002-001 Centrifugal Switch

The Century Motors 629002-001 Centrifugal Switch is a safety and performance-enhancing part used in single-phase induction motors that are used in HVAC systems like fans, blowers and air handlers. It operates based on the centripetal force occasioned by the spinning of the motor to either isolate or join electrical connections present in the circuit of the motor. As the motor picks up speed, the centrifugal force switches the start winding off and the motor runs at efficiency in its running mode. This process avoids the motor drawing high current during start-up and provides reliable motor operation which in turn enhances the system efficiency and motor durability.
