QQHEPI Remove mounting screws on switch cover plate and take off plate. With cover plate removed, you'll see two screws holding switch in switch box. If necessary, remove screws, and carefully pull switch out of box as far as attached wires allow. If there are two screws with wires attached, switch is a simple ON/OFF (single-pole) type. If there are three screws with wires attached, you're working with a more complicated type called a three-way switch.|Nippon Ichi Software
