The ignition switch is a crucial component of the car cabin. You cannot start the engine or turn on the accessories without ignition switch. One should not force the key or any tool inside the ignition switch. It might damage the entire ignition system costing you trouble. Do not put extreme pressure while inserting the keys as well.

Let us find the mechanism behind four ignition positions here.
1. Lock – First Position

It is the first position of the ignition switch. The manufacturers describe lock as the OFF position. You have to rotate the key clockwise to turn on the ignition switch. The lock position is to insert the keys only. There is no effect on the steering wheel or other accessories in the lock position. You can take the keys out only in the lock position.


Why not turn on the ignition switch repeatedly?

2. Accessory/ Acc – Second Position

Wondering what does acc stand for in cars ignition system? It is the accessory mode. You can use some of the standard accessories in this mode. Accessory or Acc is the second position in the ignition switch. Acc gives life to the radio, stereo, power windows, and seats.

3. ON Or Ignition – Third Position

The next one is the ignition position. All the electronic accessories come active when you turn on the ignition switch in this mode. According to the expert maintenance tips, the ON position is the default position in vehicles. You cannot remove the keys out from the ignition switch.

4. Start – Fourth Position

Now you can crank the engine. It is not the stopping position of the ignition system. The keys move back to ON or ignition, which is the default position. The motor starter might damage if you stop the keys here for long. Let the keys turn to default position once the engine starts.
