How To Change A Decora Light Switch

Electrical work can be daunting, but changing a light switch is a relatively simple task that can be completed in just a few minutes. By following these step-by-step instructions, you can safely and easily replace a faulty or outdated decora light switch.

Before you begin, ensure you have the necessary tools and materials:

New decora light switch
Screwdriver
Electrical tape
Voltage tester (optional)

Once you have gathered your tools, follow these steps to change your decora light switch:

Step 1: Turn off the power:

Locate the circuit breaker or fuse box that controls the light switch you are replacing. Flip the breaker to the "off" position or remove the fuse.

Step 2: Remove the faceplate:

Use a screwdriver to remove the two screws that hold the faceplate in place. Gently pull the faceplate away from the wall to expose the switch.

Step 3: Disconnect the wires:

Use a screwdriver to loosen the screws that hold the wires connected to the switch. Carefully pull the wires away from the switch terminals.

Step 4: Remove the old switch:

Once the wires are disconnected, you can remove the old switch from the electrical box. Gently pull the switch straight out.

Step 5: Install the new switch:

Insert the new switch into the electrical box and align the mounting screws with the holes in the box. Tighten the screws to secure the switch in place.

Step 6: Connect the wires:

Connect the wires to the new switch terminals. Be sure to match the colors of the wires to the correct terminals (black to brass, white to silver, and green or bare copper to ground).

Step 7: Secure the wires:

Use electrical tape to secure the wire connections. Wrap the tape around the connections several times to ensure a tight and secure fit.

Step 8: Reinstall the faceplate:

Align the faceplate with the switch and secure it with the two screws. Ensure the faceplate is flush against the wall.

Step 9: Turn on the power:

Return to the circuit breaker or fuse box and turn the power back on. Test the switch to ensure it is working correctly.

Changing a decora light switch is a straightforward process that can be completed quickly and easily. By following these steps carefully, you can safely and effectively replace a faulty or outdated switch.
