hmm, do we want to allow negatives too?

I don't see a reason to - position should just be a non-negative index representing the possible positions. The only case I can think of is if we wanted a negative position to be an error state, but I don't see that being useful. In error cases, the handlers should return errors.

I'm thinking of the most common toggle switch to me - the power drill direction - where that switch makes sense to me as a -1, 0, 1 switch. But meh 🤷🏼‍♀️
