3 Lights on One Switch Wiring Diagram

If you are looking to install multiple lights in a room and control them all with one switch, then you have come to the right place. In this article, we will guide you through the process of wiring three lights to one switch. This is a common scenario that homeowners often face, and we believe that our instructions will help you get it done right.

What You Will Need

Before we begin, here are the items you will need:

Item Quantity
Wire stripper 1
Wire nuts 6
Electrical tape 1 roll
Three lights 3
14-3 wire 1 roll
Switch 1

Step-by-Step Instructions

Step 1: Turn Off the Power

The first step is to turn off the power to the circuit that you will be working on. Locate the circuit breaker that controls the switch and turn it off. This is extremely important to ensure your safety.

Step 2: Remove the Old Switch

Next, remove the old switch from the wall. Use a screwdriver to unscrew the switch plate and then gently pull out the switch. Be careful not to damage any wires in the process.

Step 3: Connect the Wires

Now it’s time to connect the wires. Take the 14-3 wire and strip off about 1 inch of insulation from the ends of each wire. There should be three wires: a black wire, a white wire, and a red wire.

Connect the black wire from the 14-3 wire to the black wire from each of the three lights. Use a wire nut to secure the connection.

Next, connect the white wire from the 14-3 wire to the white wire from each of the three lights. Again, use a wire nut to secure the connection.

Finally, connect the red wire from the 14-3 wire to the black wire on the switch. Use a wire nut to secure the connection.

Step 4: Mount the Switch

Mount the switch back onto the wall and screw in the switch plate. Make sure that it is securely attached to the wall.

Step 5: Turn On the Power

Finally, turn the power back on at the circuit breaker. Test the switch to make sure that it is working properly. All three lights should turn on and off when the switch is toggled.
