As car ignition system parts, the automotive ignition switch is used to connect or disconnect the starter, ignition, and electrical circuits.
Ignition switches usually have four positions: LOCK, ACC, ON, and START.

ACC (Accessory). In this position, accessories like the radio and headlights can be used, but not the air conditioner.
ON. In addition to the engine, all other basic equipment is on, and the steering wheel is unlocked. The air conditioner can be used, but its cooling effect is not very good. When driving normally, the key is in the ON position, and all electrical circuits in the car are working.
START. In this position, the engine starts, fuel is consumed, the car is started, and the air conditioner's cooling effect improves. The START position is for starting the engine, and it automatically returns to the ON position once the engine has started.
