This almost sounds like you have a SPDT-MOM(NC/NO) switch. This is a momentary contact switch with one set of contacts normally closed and one set normally open. I've seen a bunch of these show up at electronics stores lately (haven't got a clue why). You need to make sure that both sets of contacts are open when the switch is idle and only one set is closed when thrown (a different set for each direction). Sorry if this sounds a little simple minded but I'm really not electrically savvy (much less electronic). Now if this were software.... <br />
