I have a combination device, two switches on one device, two terminals on each side. The power is coming into the switch along with two separate lights. I want to control one light with one of the switches and the other light with the other switch. Do I connect all three white wires together; the black from power source to the terminal with a terminal fin ( joining both terminals) the other two black wires from the lights on each of the terminals on the other side of switch? If I'm wrong, please suggest the correct method. Thanks.
