What is a centrifugal relay?

A centrifugal relay is an electromechanical device that uses centrifugal force to operate its mechanism, typically found in automotive applications for controlling various functions like ignition or starting systems. As the speed of rotation increases, the relay's weights move outward, closing or opening electrical contacts to activate or deactivate connected circuits. This allows for automatic operation based on engine speed, improving efficiency and safety. Centrifugal relays are often used in applications where timing is critical and can be found in various machines and equipment.
