Microswitch with a broken terminal tab: replace the switch, don't move the wire
If a terminal tab snaps off a playfield microswitch, don't solder the wire to one of the other tabs. Each tab is a different contact (common, normally open, normally closed), so moving the wire makes the switch read permanently closed or open. Fit a new microswitch with the same actuator and wire it exactly as the old one was.
