PC, I've fried switches that way too.

If you hit it at an angle, or too light of a push, and don't get positive contact it acts just like a little arc welder inside. Once the contact points are burnt the switch becomes a point of resistance and can heat up the wires.

I did pull one apart once and clean it a surprising amount of life out of it after that. Year or so IIRC.
