So what do they do after they actually use the switches a couple of times and then they are both up? :grin:

True-- but when they are both up the circuit is also open. Only when one is up and the other down is the circuit closed. Many people only use one end of the 3 way and they like the switches to be down when off. I do it more for myself when testing out a house. If there is a short anywhere in the switching I can tell immediately--- all switches down and one by one I turn them up to see if there is a problem. It's not that hard to do, it just takes a little more concentration.
