Given a power supply that needs 120 volts AC input, I'd like to use a
small front-panel power switch at some low voltage, not run the AC
line up to the front panel.
 
Do people make SSRs that would do that, accept a low-voltage switch
closure to switch AC?
 
 

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.
