How to wire rotary switches?
I have two rotary switches with 6 (six) positions each. To control ( 8 different model railroad tracks)...(12 volts on each track) The switches (from radio shack) have all seperate positions with (I assume) the power supply from the two terminals in the middle of the switch. Is there a way to identify the polarity of the leads or am I even connecting them properly??? HELLLPPP!!!!
