Tesla1856,
I bought the same switch you are considering for the ignition cutoff. Don't make the same mistake - it's for non electronic ignition (magneto) engines. I used a receiver battery switch for the ignition kill. Just put it between the ignition and battery. Works great. Consider a second way to kill the engine from your radio - just an extra measure of safety. The other switch made by EMS could work for each of your batteries (three switches).
