- Remove Switchplate and Switch- Use a flathead screwdriver to remove the switch cover. And head screwdriver to remove the existing switch from the box.

- Remove Wires from Old Switch- Use a screwdriver to loosen the screws holding the electrical wires on the side of the switch, and then disconnect the switch itself. It is important to replace old wires because the life of an electric wire is 50-70 years.
- Attach New Switch- There are three different colored wires, they are white, black, and bare copper. Identify them and attach the new light switch to the wires in the same way they had been attached to the old switch. If your wire is composed of small wires, use a plier to gently twist the ends of the wires to make it whole again.
