30A Double Pole, Double Throw Switch, Ivory

any double pole switch will work for what you seem to be asking. do a web search to learn what double pole means. in short, a single pole switch means there is one wire that connects to another wire. but a double pole switch means the switch has two separate _electrical_ switches built into the one physical switch. for only on/off switche(s) tho, you only need a single throw switch tho, so a double throw is extra that you won't need for only an on/off circuit.
