About that switch, I'm trying to image how that will allow selection of 2 different inputs to a common out. Or said differently, one set of 5 wires is off when the other set is connected to the output contacts. If one side had 8 contacts and the other had 4 for output, it would connect all 8 wires to output when the switch is on. Thinking about that gave me an idea... I know some contacts can be purchased with both NO and NC pairs. If the panel was wired to NC and the spindle output from BOB or controller to NO, that would accomplish what I'm tryin to do?
