It's a double pole/single throw. Can't make it do what it CANNOT do.In the 0db position, no continuity anywhere, in the -20db position, continuity between separate contacts to another set, isolated without the bus bar.Really, all it is a shunt to ground through a 22K resistor, take it back to 0db and it removes the 22k from the equation. I opened the switch up and no chance to make it behave differently.
