That's a lot of questions to ask:
There are several types of ignition switches.
I would say 99.99% don't have any kind of resistor in them.
A basic explination is:
Accessory position: Only the radio and a minimal amount of circuits.
Start engages the starter solenoid, and a secondary ignition wire, for the
ignition system, and injectors, when you relaese it. The primary wire for
the ignition is energised, and the starter contacts are released.
That's about the most generic explination I can givw.
I hope this helps.
