Quoted from Law:Super glue is one of the worst possible adhesives to use in a pinball machine. It WILL fatigue and shear with vibration. "Shear" is maybe generous, I mean it basically powders itself after a fairly short while. This is assuming we're talking about normal super glue. Fair warning to anyone reading this thread that's thinking about using it.
And that particular hack is probably the WORST possible place to use it with a spring pushing against the glue. WTF? I mean, if you were a knucklhead and wanted to defeat the switch, wouldn't you just cut the wires and tape together as needed? The superglue thing has to be the higher-work fubar way to fix this!
