Michael, I really like the Harmony switch idea. It's very clean and avoids any motion related problem with the wires and the sliding table. I'm curious as to the button force issue that you mention. Since the transmitters have no batteries or power supply, I have to assume that they get their power from the physical actuation of the button and hence are hard to press. Do you think this is a problem with the end of the table installation where you are curling your hand around to press it instead of a straight punch like on a panel?
