Not
really. The replacement of one expensive, failure-prone
mechanical part with a cheap-and-getting-cheaper silicon part is
almost always a good thing.
I won't quibble wth the "cheaper" part, but exactly how "failure-
prone" are microswitches? I can remember only one failing and that
was on an automatic coffeemaker (handled lots of current in a wet
environment; arcing eventually destroyed the contacts).
