Step-by-Step Guide

Step 1: Turn Off Power

Before you start, make sure to turn off the power to the switch at your home's main electrical panel. This is an important safety step that should not be overlooked.

Step 2: Remove the Old Switch

Remove the screws holding the switch cover plate. Pull the switch out of the box as far as the wires will allow. Use a voltage tester to confirm the power is off.

Step 3: Disconnect Wires

Disconnect the wires from the old switch. Remember to pay attention to where the wires are connected as you'll need to connect them in the same way on the new switch.

Step 4: Connect New Switch

Connect the wires to the new switch in the same way they were connected to the old one. If necessary, use your wire strippers to expose more of the wire.

Step 5: Secure New Switch

Push the new switch back into the box and secure it with screws. Replace the cover plate.

Step 6: Test Your Work

Turn the power back on at the main electrical panel. Test the new switch to make sure it's working properly.

Safety Tips

• Always turn off power at the main electrical panel before starting.

• Use a voltage tester to ensure the power is off before touching any wires.

• Never touch bare wires or terminals until you have confirmed that the power is off.
