How to Wire a Light Switch with Outlet: DIY Guide

Are you planning to replace your old light switch with a new one that comes with an outlet? If so, you came to the right place. In this article, we will explain step-by-step how to wire a light switch with an outlet. We will start with the basics and cover everything you need to know, from tools and materials required, to safety precautions, and wiring diagrams.

Tools and Materials Required

Before we begin, let’s review the tools and materials required for this task. You will need:

  • Wire stripper
  • Wire cutter
  • Screwdriver (flathead and Phillips)
  • Electrical tape
  • Outlet and switch combo unit
  • Wire connectors (wire nuts)
  • Electrical cable (either 14-2 or 12-2)

Make sure you have all the required tools and materials before you start.

Safety Precautions

Working with electrical wiring can be dangerous, so it’s important to take some safety precautions to avoid accidents:

  • Turn off the power to the circuit you will be working on at the main electrical panel
  • Test the wires with a voltage tester to make sure there is no power flowing through them
  • Wear safety glasses and gloves to protect yourself from any electrical shocks or burns
  • Work in a well-lit and ventilated area

If you are not comfortable working with electricity, it’s best to hire a licensed electrician to complete the task.

Wiring Diagram

Before we start wiring, let’s take a look at the wiring diagram for a light switch with an outlet:

Wire Color Function
Black Hot Power to switch
Red Hot Switched power to outlet
White Neutral Common neutral for both switch and outlet
Bare copper or green Ground Ground for both switch and outlet

Now that we covered the basics, let’s start with the step-by-step process:

Step 1: Turn off the Power

Turn off the power to the circuit you will be working on at the main electrical panel. To be sure the power is off, use a voltage tester to test the wires.

Step 2: Remove the Old Switch

Remove the old switch from the wall. Unscrew the switch plate and unscrew the switch from the electrical box.

Step 3: Prepare the Wires

Strip about ½ inch of insulation from the ends of the wires. If the wires are too short, you can extend them using wire connectors.

Step 4: Install the New Switch

Attach the new switch to the electrical box using screws. Make sure it’s level and centered.

Step 5: Connect the Wires

Connect the wires to the new switch. The black wire connects to the bottom terminal (hot), the red wire connects to the top terminal (switched power to outlet), the white wire connects to the silver terminal (neutral), and the bare copper or green wire connects to the green terminal (ground).

Step 6: Install the Outlet

Attach the outlet to the switch using screws. Make sure it’s level and centered.

Step 7: Test the Circuit

Turn the power back on and test the circuit. Check if the switch and outlet are working properly.
