You might consider one of these - TUV rather than
UL listed.

As I read the replies I am wondering. Although
the apparatus is designed to produce high voltages one should not
be getting shocked simply by flipping a switch. Is the problem really too much current causing the
switch to destroy itself through arching, or are you getting a
high voltage spike from the apparatus being fed back to the mains?
Or perhaps both? If it is a high voltage spike you might want to
consider some power input filtering (albeit in this case it is
really output filtering), a better ground, overvoltage protection
etc. Just want to make sure you understand the true source of the
problem - safety first.

We use these for all our vacuumm pumps:
