Its main function is to control the power flow of various systems within the vehicle, including the ignition system, the fuel system, and accessories such as the radio and interior lights.
Starting the Vehicle: When you insert the key into the ignition lock cylinder and turn it, the ignition switch detects this action. It then sends an electrical signal to the starting motor, allowing it to crank the engine and start the vehicle.
Power Distribution: Once the engine is running, the ignition switch delivers power to the engine's ignition system, fuel system, and other important components. It ensures that the engine continues to get the power to run smoothly.
Security: Many modern ignition switches have anti-theft features. These may include password keys, electronic immobilizers, or other anti-theft mechanisms.
In general, the ignition lock cylinder switch is crucial to the normal operation of the vehicle ignition system. It can not only start the engine, but also control the power distribution of various systems to ensure the safety of the vehicle.
