Cause that's the way Ford designed it...

It's the same on other cars too, I think it's so you can't accidentally leave them on. Actually I don't have fog lights, I have the driving lights. You have to pull out on the switch to turn them on. However if the switch is in the "auto" position the driving lights will illuminate during the daytime when the engine is on.
