Two Switch Wiring Diagram – An Easy Guide for Beginners

Two switch wiring diagram is a commonly used electrical wiring configuration. It is used to control the lighting fixture from two different locations. This wiring setup is usually found in hallways, staircases, and large rooms where one light fixture needs to be controlled from multiple locations. In this article, we will guide you through the process of wiring a two switch lighting circuit.

Preparation

Before starting the wiring process, it is important to gather all the necessary tools and materials. Here is the list of things you will need:

Tools Materials
Screwdriver Electrical wires
Wire stripper Two single-pole switches
Wire nuts Electrical tape
Non-contact voltage tester Wire connectors

Once you have all the tools and materials, follow these steps to wire a two switch lighting circuit:

Step 1: Turn off the Power

Before starting any electrical work, it is important to turn off the power to the circuit that you will be working on. Use a non-contact voltage tester to confirm that there is no electricity flowing through the wires.

Step 2: Run Electrical Wires

Run the electrical wires from the light fixture to the two switch boxes. Use a wire stripper to remove about 3/4 inch of insulation from the end of each wire.

Step 3: Connect the Wires to the Switches

Connect the black wire from the power source to the common terminal of the first switch. Connect the black wire from the light fixture to the common terminal of the second switch. Connect the white wires together with a wire nut and attach them to the metal box. Finally, connect the ground wire to the green screw on the switch.

Step 4: Secure the Switches in Place

Once you have connected the wires, secure the switches in their respective switch boxes. Make sure the switches are lined up correctly and the cover plate is aligned before tightening the screws.
