This past weekend I was able to fix the ice dispenser on my fridge using a standard pinball switch, it was the exact same thing. When the controller board went on my central AC I was able to use some parts to make a temp fix while waiting for a new board. It would run non-stop, so we would control it manually at the electric panel. One of my garage door switches is a "Rumble" button (I assume from Royal Rumble). After the fixes I always remind my wife how much money we just saved by having all this pinball stuff around.
What non-pinball things have you fixed with pinball parts?
