Hi, i have a Cushcraft PS4A switcher, and would like to know the power required on the wires comming into the shack to change the polarity. I guess i'll also need to install a toggle switch for right and left. 73 de Scott VE6ITV

Scott,
Switchers normally use a 12 DC relay. Unpowered, you get one direction, powered the other. Which is the unpowered default can depend on the manufacturer, and/or how you wire it up. Cushcraft has the installation drawings on their web site, but I wasn't able to find the default value.
