The ignition switch is equipped with an anti-theft locking device, a starter re-engagement lock when the engine is running, and a backlight for the ignition socket.
The locking rod of the anti-theft device extends when the key is removed from the lock (the key can only be removed in position "0"). When the key is turned from position "0" to position "I", the locking rod retracts into the lock, contacts "30" and "15" of the ignition switch close.
When the key is turned to position "II", voltage is also supplied to the starter relay. From this position, the key automatically returns to position "I" under the action of the spring. You can turn the key to position "II" again only after first turning it to position "0".
