Ignition switch — bench test

At the ignition switch, the correct closure of the contacts is checked at various key positions (tab. 22), the operation of the anti-theft device and the operation of the blocking device against restarting the starter. The connection diagram of the ignition switch is shown in fig. 142.



The locking rod of the anti-theft device must extend when the key is set to position III (parking) and take it out of the castle. The locking rod must retract after turning the key from position III to position 0 (turned off). The key must only be removed from the lock in position III.

The locking device against restarting the starter must not allow the key to be turned again from position I (ignition) to position II (starter). Such a turn should only be possible after the key has been previously returned to position 0 (turned off).
