Why ignition switch turn?

The ignition switch turns because it is connected to the steering column. When you turn the key, the steering column moves, which in turn moves the ignition switch. The ignition switch then sends a signal to the starter, which starts the engine.

Here is a more detailed explanation of how the ignition switch works:

1. When you insert the key into the ignition, it makes contact with the ignition switch.

2. The ignition switch is connected to the steering column. When you turn the key, the steering column moves, which in turn moves the ignition switch.

3. The ignition switch then sends a signal to the starter solenoid.

4. The starter solenoid engages the starter motor, which starts the engine.

The ignition switch is a critical part of the starting system. If the ignition switch is not working properly, the engine will not start.
