Wiring two switches together can be a daunting task for some, but with a little knowledge, it can be an easy job. In this article, we will walk you through the steps of wiring two switches together and provide you with a wiring diagram to simplify the process.
What Are Two-Way Switches?
Two-way switches, also known as single-pole double-throw switches (SPDT), are commonly used to control a light from two different locations. This is useful in rooms with multiple entrances, such as stairwells or hallways. Two-way switches work by connecting and disconnecting the circuit from the light bulb, which allows for control from multiple locations.
Before we get into the wiring diagram, it is essential to understand the different components of the switch.
Components of Two-Way Switches
Two-way switches consist of three terminals – two brass-colored screws and one dark-colored screw. The brass screws are known as traveler terminals and are used to connect the two switches together. The dark screw is called the common terminal and is used to connect the switch to the light or the power source depending on the switch position.
Now that you understand the components let’s move to the wiring diagram.
Wiring Diagram for Two-Way Switches
Below is a wiring diagram for two-way switches. The diagram shows two switches connected together to control a light bulb from two different locations.
| Terminal | Wire Color |
|---|---|
| Common | Black |
| Traveler | Red |
| Traveler | White |
It is essential to note that the wiring diagram represents the basic wiring scheme for most standard two-way switches. However, the wiring may vary depending on the brand and type of switch you are working with. Always refer to the manufacturer’s instructions before starting any electrical work.
Step-by-Step Guide to Wiring Two-Way Switches
Now that we have looked at the wiring diagram let’s move to the step-by-step guide to wiring two-way switches.
Step 1: Turn Off Power
The first step is to turn off the power to the switch you will be working on. This can be done by switching off the circuit breaker in your electrical panel or removing the fuse.
Step 2: Remove Switch Cover Plate
Next, remove the cover plate from the switch. This will give you access to the switch terminals.
Step 3: Connect the Wire to Common Terminal
Take the black wire and connect it to the common terminal on the switch by wrapping it clockwise around the screw and tightening the screw with a screwdriver.
Step 4: Connect the Traveler Wires
Take the red and white wires and connect them to the traveler terminals on the switch by wrapping them clockwise around the screws and tightening the screws with a screwdriver.
Step 5: Replace Switch Cover Plate
Finally, replace the switch cover plate by screwing it back into place.
