Switzerland has some of the largest corporations in the world in the pharmaceutical industry, and they're by far leaders in the watchmaking industry. Banking isn't the only business they rely on.
I do think that Switzerland might have a problem with banks soon or later, but currently I don't see such situation clearly developing (rather more in Germany with Commerzbank & Deutsche Bank?).

The medical-related area has probably others, but I personally have no clue about that.
