	The mercury interruptors have certainly been used with success.  For
example, Antonio has a description of such an arrangement on his web
page, if you look carefully.  Look at:

and dig around.  Neat page!!!

	That device is similar to that which was/is known as a Wehnelt
interruptor, and was and was used where the only source of voltage for
exciting an induction coil was DC.
