I am adding a light to a pole. Because of where the switch is and some wires that are already in place it would be most simple to run the hot wire through the single pole switch rather than the common. I am no expert but from reading I see that generally the common is routed through the switch. I seem to recall from my high-school electricity/electronics class that either the hot wire or the common can be routed through the switch since all it does is complete the circuit when it is closed? Is this correct? I hope so because it will make my wiring much more simple. Thanks very much for any input!! It's at my home, 120 service, of course I am also running a ground wire.
