I've only experimented with on / off type switches so far, like DIP switches and rocker switches. I was thinking about creating a circuit that could either be powered by DC or battery and the way I thought I'd go about it would be by having the two power sources going into some kind of switch, where I would choose to allow current to flow into the circuit from either battery or DC... kinda like railway points, but in reverse... I think.
What kind of switch do I need to purchase for that? I don't think it's a toggle switch, but I had originally inferred it might be, from the name.
I also thought about having a simple switch decision tree that was two deep, the first selecting where the power is coming from, and the second being whether the circuit was on or off at all - so current only flows if a) the mains or battery has power and b) if the circuit is on... is there a switch type that would allow me to do this in one device, like:
Switch position 1 = circuit off and no power from DC or battery.
Switch position 2 = circuit on and power from DC.
Switch position 3 = circuit on and power from battery.
