I'm willing to believe that the best electronic switches can last longer than the best mechanical switches, but there's so many more ways for an electronic switch to fail that it's a lot easier for me to trust an off-the-shelf mechanical switch than an off-the-shelf electronic one, especially if the cost of failure of the mechanical switch is just an easy swap in of another one.

- heisenbit 3y agoThe thing is: It is moving as there are vibrations. There is a fair amount of acceleration and a high frequency. Then there are temperature cycles as the machinery is not perfectly isolated. There is migration of atoms at contact boundaries. Plenty things move.
