Where is the terminal? And does the positive go to the top screw or the bottom

Hello, this is a single pole toggle light switch part # 1301-7. It will have two brass terminals or screws. Terminals is another industry term and a green ground screw, which you must connect to ground. Depending on the number of wires in the wall box will determine how you wire it. I must urge you to call an electrician or look at Utube for wiring videos. Thank you.
