I'd be interested in the answer to this too only out of curiosity. I seem to recall that there is something like an arm attached to the airflow flap and as the flap opens it moves the position of the arm on the electrical contact patch.
I don't think you would have any problems from an electrical point of view but where you might have an issue is that in flipping it the flap is then working with or against gravity in the opposite direction which could alter the behaviour of the arms movement.
I could be wrong though and the flow air in the tube may be enough to overcome any issues.
Good luck and please post the outcome
