Switch Basics
A 3-way switch is a type of light switch that allows you to control a light source from two different locations.
For example, you could have a light switch at the top and bottom of a staircase. Flipping either switch would turn the light on or off.
A one-way switch, on the other hand, can only be controlled from one location.

Can a three-way switch be used as a single pole switch?
The answer is yes, but only if the switch is wired correctly. If the switch is not wired correctly, it will not work as a single pole switch and may even cause damage to your electrical system. Therefore, it is important to consult with a qualified electrician before attempting to wire a three-way switch as a single pole switch.
Eliminate and Convert
So, if you wanted to turn a 3-way switch into a one-way switch, you would need to remove one of the switches.
The easiest way to do this is to disconnect the wires from one of the switches and cap them off so they don’t touch anything else. That way, you can be sure that the electricity won’t flow through those wires and cause a short circuit. You can then install a standard one-way (single pole) switch in its place.
Following these steps will allow you to safely convert a 3-way switch into a single pole switch.

FAQ
What is the difference between single pole and three-way switch?
A single pole switch is a type of switch that is used to control a light or an electrical device from a single location. It has two terminals: one for the incoming hot wire and another for the outgoing wire to the device. On the other hand, a three-way switch is a type of switch that is used to control a light or an electrical device from two or more locations. It has three terminals: one common terminal and two traveler terminals.
Why is it called 3 way switch?
It is called a three-way switch because it allows you to control a light or an electrical device from three or more locations. In other words, you can turn the device on or off from one location and then turn it off or on from another location.
Can a 3 way switch be wired as a single pole?
Yes, a three-way switch can be wired as a single pole switch. To do this, you need to connect the incoming hot wire to the common terminal and the outgoing wire to either one of the traveler terminals. The other traveler terminal will be left unused. This will essentially convert the three-way switch into a single pole switch.
Why does a single pole switch have 3 wires?
A single pole switch has three wires because it typically includes a ground wire, a hot wire, and a neutral wire. The ground wire is used to provide a path for electrical current in case of a short circuit, while the hot wire is used to carry the electrical current to the device being controlled. The neutral wire provides a return path for the electrical current back to the electrical panel. However, not all single pole switches require a neutral wire, and some may only have two wires.
