A faulty ignition switch might momentarily turn itself off and come back on when the contacts are bad. Check if the ignition switch feel hot after driving for a short while, if yes, it is failing.
The only connection between a bad alternator and ignitin switch is that when the ignition switch fails, it does not allow the alternator to charge as ignition switch power supply to alternaotr is missing. A faulty alternator on the other hand would not affect the ignition switch.
