Quoted from MK6PIN:Sarcasm, right?....pinball machines use dpst switches for power, which in essence is a physical disconnect from power...
Unless, as Lloyd pointed out, you leave something plugged into the service plug ( like a soldering iron...so I've heard)
old ones use single pole, old filters leak a bit...
Quoted from MK6PIN:Ahh....I learned something new, and stand corrected....retract my previous statement in reference to machines you state.
we all learn stuff every day, thats half the fun...
i should add "in theory" to the 'old filters' thing.. i have not personally measured it but they do have a leakage rating so it seems possible.. it will be trivial like 2mA for example.. best way will be just measure it
