On a diesel the key is more of a "electrical master switch"
It does not cause "ignition" of the fuel like a spark plug in a car.

I don't really know. Someone else will know.
I work with large 16 cylinder 150 liter engines and we don't have ignition switches.
On ship we start with compressed air so we dont need an electic starter or generator.
