Note that my original request was for sources and solutions to 48V
switchgear for signal sources. Nobody has provided that yet, although I
appreciate the efforts. Del City makes inexpensive SPST and SPDT switches
rated (by them) 24V 50A; these ought to work 48V 1/20th amp. DPDT are 21A,
14V. That's the closest I have found. Anyone else?
