What are the four positions of the car ignition switch?

[LaMicah]

The four positions of the car ignition switch are START (starting position), ON (power-on position), ACC (accessory power-on position), and LOCK (locking position). Below are the detailed introductions of each position: 1. START position: Starting position. When the key is turned to this position, the starter circuit is connected, which drives the engine to operate and start. After releasing, the key will automatically return to the ON position. 2. LOCK position: Locking position. This is the position where the key is inserted and removed. At this time, except for the anti-theft system and interior small lights, the vehicle's circuits are completely turned off, and the steering wheel is locked. After locking the car, the key will be in the LOCK state, where the key not only locks the steering but also cuts off the entire vehicle's power supply. 3. ACC position: Accessory power-on position. When the key is turned to this position, the accessory circuits are connected, and devices such as the radio can be used. The ACC state provides power to some of the car's electrical equipment, such as the CD player and air conditioning. 4. ON position: Power-on position. When the key is turned to this position, all vehicle circuits are connected, and the system prepares necessary operations and self-checks for starting the engine. The key remains in this position during normal driving.
