2 Way Switch Wiring Diagram PDF

2 way switches are some of the most commonly used switches in household wiring systems. They are used to control lighting systems or any other electrical appliances that can be switched on/off from two different locations. However, understanding how to wire a 2 way switch can be a challenging task, especially for individuals who are not familiar with electrical wiring. In this article, we will provide a detailed 2 way switch wiring diagram PDF that can help you understand how to wire a 2 way switch like a pro.

What Is A 2 Way Switch?

A 2 way switch is a type of electrical switch that can control a light or an electrical appliance from two different locations. For instance, if you have a light in your hallway, the 2 way switch can turn it on or off from either end of the hallway. It is important to note that the 2 way switch is not the same as a double pole switch, which is used to control separate circuits.

Parts Of A 2 Way Switch

Before we dive into the 2 way switch wiring diagram PDF, let us understand the different parts that make up a 2 way switch. The parts include:

Part Description
Switch Mechanism The switch mechanism consists of the actual switch that is used to turn the light or electrical appliance on or off.
Terminals The terminals are the points where the wires connecting to the switch are attached. Each terminal is marked as either “common,” “L1,” or “L2.”
Faceplate The faceplate is the cover that goes over the switch mechanism once it has been installed on the wall.

As shown in the diagram, a 2 way switch has three terminals: “common,” “L1,” and “L2.” The common terminal is connected to the source of power, while L1 and L2 are connected to the light or electrical appliance. When the switch is in the “on” position, the current flows from the common terminal to L1, and when the switch is in the “off” position, the current flows from the common terminal to L2.

Step By Step Guide To Wiring A 2 Way Switch

Here is a step-by-step guide on how to wire a 2 way switch:

Step 1: Turn Off The Power Supply

Before you start wiring the switch, it is important to turn off the power supply to the circuit. You can do this by flipping the circuit breaker or removing the fuse that powers the circuit. This helps to prevent electrical shocks or injuries during the wiring process.

Step 2: Prepare The Wires

Prepare the wires that will connect to the switch. You will need three wires: one from the power source, one to the light or appliance, and one to connect to the second switch location. Strip the ends of the wires to expose about 1/2 inch of copper wire.

Step 3: Connect The Wires To The Switch

Connect the wires to the terminals on the switch. The common wire should be connected to the common terminal, while the other two wires should be connected to L1 and L2. Tighten the terminal screws to ensure that the wires are securely attached to the switch.

Step 4: Install The Switch

Once the wires are connected, install the switch onto the wall box. Fasten the switch with screws to ensure it is secure.

Step 5: Turn On The Power Supply

Turn the power supply back on by flipping the circuit breaker or inserting the fuse. Test the switch to ensure it is working correctly.

FAQ

1. What is the difference between a 2 way switch and a 3 way switch?

A 2 way switch can control a light or appliance from two different locations, while a 3 way switch can control a light or appliance from three different locations. A 3 way switch also has four terminals instead of three.

2. How do I know which wire is the common wire?

The common wire is usually black or red, but you may also use a voltage tester to test the wires and identify the common wire.

3. Can I use a 2 way switch to control a ceiling fan?

Yes, you can use a 2 way switch to control a ceiling fan, but you will need to ensure that the switch is rated for the current and voltage used by the fan.

4. Can I wire a 2 way switch myself?

Yes, you can wire a 2 way switch yourself, but it is important to follow the instructions carefully and ensure that you turn off the power supply before starting the wiring process.

5. What is the purpose of a 2 way switch?

A 2 way switch is used to control the lighting or electrical appliances from two different locations. It is commonly used in hallways or staircases to turn on lights from either end of the hallway or staircase.
