【Product Features】1.The electromagnetic switch is used to precisely control the operation of the starter motor. When the driver turns the key or presses the start button, the electromagnetic switch connects the circuit and pushes the pinion gear to engage with the flywheel ring gear. 2. Automatic disengagement mechanism: Once the engine is successfully ignited and starts running, the pinion gear of the starter motor will automatically disengage from the flywheel ring gear to prevent damage to the starter motor due to excessive engine speed. 3. Strong durability: Due to the need for frequent use and the possibility of high temperature, vibration and other factors in the working environment, the starter motor must have good durability and reliability.
