Not to steal the topic but at a swap meet yesterday I bought two
Ohmite rotary non-shorting switches (2 bucks each NIB) rated at 30A
300V 60 cycles, 150 v. between contacts. Single wafer six positions.
I wonder how the 60 cycle voltage rating translates up into RF v. at
1.8 MHz and higher. I have big Radio switches but I wonder if the
Ohmites are good as RF bandswitches or not.
