Have you ever wondered how to install or replace a 2 way light switch in your home? Being able to control your lights from two separate switches can be a game changer for your home’s lighting system. In this article, we will provide a step-by-step guide on how to wire a 2 way light switch with a detailed wiring diagram.
What is a 2 Way Light Switch?
A 2 way switch, also known as a double pole switch, is a type of switch that allows you to control a single light or group of lights from two different locations. This type of switch is commonly used in hallways, stairwells, and large rooms where one switch may not provide adequate lighting control.
There are two basic types of 2 way switches: single pole and three-way. In this article, we’ll focus on wiring a single pole 2 way switch.

Step-by-Step Guide to Wire a 2 Way Switch
Step 1: Turn off Power
The first step in any electrical installation is to turn off the power at the circuit breaker or fuse box. This will ensure your safety by preventing any electrical shock or damage to your equipment.
Step 2: Remove Existing Switch
Using the flat-head screwdriver, remove the cover plate and screws that hold the existing switch in place. Carefully pull the switch out of the wall and disconnect the wires from the switch.
Step 3: Identify Wiring
Before you begin wiring your new switch, identify the wiring that is currently in place. You will need to determine which wire is the hot wire (usually black), the neutral wire (usually white), and the ground wire (usually green or bare copper).
Step 4: Connect Wires
Using the wire strippers, strip approximately 1/2 inch of insulation off the ends of each wire. Connect the hot wire to the black screw on the new switch and the neutral wire to the silver screw.
Connect the two traveler wires to the two brass screws on the switch. It does not matter which traveler wire goes to which brass screw since they are interchangeable.
Step 5: Secure Switch
Once all the wires are connected, carefully tuck them into the box and secure the switch with screws. Replace the cover plate.
Step 6: Test Switch
Turn the power back on at the circuit breaker or fuse box and test your new 2 way switch to ensure it is working properly.
