Take the cover off the engine and you should be able to locate either one or two wires running from the ignition into the kill switch. Unplug the wire(s) and see if jumping or breaking the connection kills it.
That wrapped harness wire has to terminate in plugs, or a paccon, at one end or the other. Odds are the switch is either worn or corroded and it is very possible that if you can access it and clean the contacts, it will work again without any problem.
