Let’s make sure we’re talking about the right switch first. Sounds like the RCD to me if so it should have a “Test” button on the front (a picture would be good just to be sure).

If it is the RCD there are two possibilities, either the RCD switch itself is faulty of something in the van is leaking current to earth. The RCD detects when the out of the mains isn’t the same as the current coming back and that means that current is going somewhere it shouldn’t.

Firstly switch everything off and unplug the van from the mains. If the switch still won’t switch on in almost certainly just a faulty switch.

If it’s OK and switches off again when you reconnect the supply it could still be a faulty RCD  (switching off to early) or more likely there is another fault on the van.
