I have two light sconces and they are not wired to a light switch. The old ones have a turn switch to power on the light, kind of like at a hotel. I need to figure out how I can wire a pull switch onto my new lights. The switches have a positive and a negative wire and that is it. I would figure that it would need two positive and two negative wires. How am I to wire this?

The Negatives?(Neutrals tie together)Then the Hot goes to 1 side of the switch and other terminal of switch goes to lights hot.
AC is Alternating Current, No Positive or Negative.
