"Miracle switch" failures

[JOddino]

With my switch/regulators you can tell if the wrong one is plugged in by the
fact you can't turn the system off.  I suspect others are the same.  What
Tony Stillman said in another reply is true.  We had about ten fail but
always on the ground, so I assumed it happened either at turn on or turn off
and was probably due to static electricity in the switch circuit.  We have
never had a failure of the regulator without the switch.  I considered
making a change but the problem seems to have gone away.  Either the parts
from the manufacturer are better or people are not reporting failures.
