I think Piotr Wyderski posted a cool looking circuit using a small hf pulse
transformer as isolation and coupling. Shorting the isolated LV side loaded
or stopped an oscillator or something.

The 1960s GE SCR manual showed ways to do that too but using 50/60Hz
transformers which are now not cost effective.
