Electrical Wiring Diagram for a 2-Way Switch

A 2-way switch is a type of electrical switch that allows you to control a single light fixture from two different locations. This is often used in hallways or stairwells, where you need to be able to turn on the light from either end of the hallway. The basic wiring diagram for a 2-way switch is shown below. [Image of a 2-way switch wiring diagram] The switch has three terminals: *

Line:

This terminal is connected to the power source. *

Common:

This terminal is connected to the light fixture. *

Traveler:

This terminal is connected to the other switch. The two switches are wired in parallel, so that when either switch is turned on, the light fixture will be turned on. To wire a 2-way switch, you will need the following materials: * Two 2-way switches * Three wire nuts * Two lengths of wire (14-gauge or 12-gauge) * A screwdriver

Step 1:

Turn off the power to the circuit.

Step 2:

Remove the cover plate from the existing switch.

Step 3:

Identify the wires at the existing switch. The line wire will be black or red. The common wire will be white. The traveler wire will be either blue, green, or orange.

Step 4:

Connect the wires to the new switches. Connect the line wire to the "Line" terminal on both switches. Connect the common wire to the "Common" terminal on both switches. Connect the traveler wire from one switch to the "Traveler" terminal on the other switch.

Step 5:

Secure the wires with wire nuts.

Step 6:

Replace the cover plate on the new switches.

Step 7:

Turn on the power to the circuit. Test the switches to make sure they are working properly. ## How to Use a 2-Way Switch To use a 2-way switch, simply flip the switch up or down. When the switch is up, the light fixture will be turned on. When the switch is down, the light fixture will be turned off. You can use a 2-way switch to control a light fixture from two different locations. For example, you could use a 2-way switch to control a light fixture in a hallway from either end of the hallway. ## Conclusion A 2-way switch is a simple and effective way to control a light fixture from two different locations. It is a versatile and affordable option for a variety of lighting applications.
