wiring two way light switch diagram

Two-way light switches are essential fixtures in terms of lighting control. They’re used to switch on and off the lights placed in a room from two different points. Such light switches can be operated not only by the people present in the room but even from outside the room. Understanding how these two-way light switches work encourages you to use them properly and keep things under control.

To start with, one needs to know the wiring of these two-way light switches. The best way to do it is to use a diagram such as the one below. It shows the two main components of a two-way light switch: the ‘traveler’ and the ‘common’. As you can see in the diagram, there are three electrical connections (two travelers and one common) to the two-way light switch.

In this configuration, the power supply is connected to the same point. The common connection of the two-way light switch is then connected to the load or light that you want to control. Finally, the travelers are connected to each other at the second light switch to complete the circuit. Through this circuit, the current will flow and the lights will be able to be controlled from both switches.

In simpler terms, when the common is connected to either traveler, the load is powered. When both travelers are connected, the power cuts off. Thus, when the switch is turned off at one point, the light goes off at the other end as well. This is what makes two-way switching so popular and useful. With the help of this wiring diagram, you can easily understand and install two-way light switches in your home.
