ignition wireing

hey is the ignition a constent or switched source?
i know its a stupid question but i know nothing about wireing.
(please dont ban me for my ignorance)

3 stages, ON, ACC, and START.

ok so what ur saying is at all times there is power flowing thru the ignitiion wire even when the car it self is not running.

As soon as you turn the key to ON, the ignition is hot.

There should be no power to the ignition until you turn the key to ON.

START just engages the starter.

switched… constant means there is always +12 V on it…
