What exactly happens when a check switch is preformed? Does the voltage change, go up or down or off. Is 22 hertz tone sent or what? What is it exactly that makes a switch change? I am experimenting with a Winegard Carryout portable dish. It is a automatic dish. What is it that it looks for to change from one sat to another? Like I said I am experimenting . Any help would be great. I like to see what makes things work.
