How to Separate Two Lights Controlled by the Same Dual Light Switch

If you have two lights that are currently controlled by the same dual light switch and you want to separate them, you have to rewire the switch so that each light is controlled independently. This is a detailed step-by-step guide to assist you through the process, ensuring you achieve the desired outcome without any safety risks.

Tools and Materials Needed

Steps to Separate the Lights

Step 1: Turn Off Power

The first and most crucial step is to ensure your safety. Before you begin, switch off the circuit breaker controlling the dual light switch. To double-check that the power is off, use a voltage tester to ensure there is no electrical current present. This is important to prevent any electrical hazards during the rewiring process.

Step 2: Remove the Switch Plate

Next, unscrew and remove the switch plate covering the dual light switch to access the wiring. This involves using a screwdriver to remove the screws that hold the plate in place and carefully taking it off to expose the switch.

Step 3: Un screw the Switch

Remove the screws holding the switch in the electrical box and gently pull it out. Be careful as you do this as the wires are likely connected in a specific way. Use a voltage tester to identify which wires are for each light if it's not clear from the initial inspection.

Step 4: Identify Wires

Take note of how the wires are connected. A typical dual switch setup has one common wire and two traveler wires. The common wire is usually black, and the traveler wires could be black or red. Ensure you can identify which wire connects to each light.

Step 5: Disconnect Wires

Disconnect the common wire (black). Disconnect the wires for the individual lights (if they are black or red). Disconnect the ground wire (usually green or bare copper).

Step 6: Reconfigure Wiring for Independent Control

If using two single-pole switches, reconnect the wires as follows:

Connect the common wire (black) to each new switch. Connect the wires for the individual lights (could be black or red) to their respective new switch terminal. Ensure the ground wires (green or bare copper) are securely connected to the switch ground terminals.

Step 7: Cap Unused Wires

If you are not using one of the switch positions, cap the unused wire with a wire nut and secure it with electrical tape to prevent any short circuits.

Step 8: Reinstall the Switch

Push the new switches back into the electrical box and secure them with screws. Replace the switch plate and make sure it fits securely. This completes the wiring part of the process.

Step 9: Turn Power Back On and Test

Restore power at the circuit breaker and test the switches to ensure that each light operates independently. This is a crucial step to ensure the rewiring was done correctly and does not cause any malfunctions.

Safety Tips

Ensure you are familiar with electrical work or consult a professional if unsure. Ensure the power is completely off before working on electrical components. Follow all local electrical codes and use proper tools and materials.

By following these steps, you should be able to successfully separate the two lights on the dual light switch and enjoy the comfort and convenience of independent control over each light. This process can be complex, and if you are not confident in your abilities or if local electrical codes require a licensed electrician, it is best to consult one.
