How do Dimmer Switches Work?

As we know, not all dimmer switches are of the same kind, and they may work differently. If you are considering installing a dimmer switch but do not know how it works, we have an answer cooked for anyone to understand.

Everyone knows that we need electricity to run the lights, oven, or basically for all electrical devices. But not all electrical devices consume the same amount of energy.

The dimmer switch controls the amount of electricity flowing through the circuit into the lights. And by altering the amount of electricity through the circuit intensity of the light is controlled.

The biggest benefit of using a dimmer switch is that you can customize the brightness of the light based on your activity and lifestyle.

Moreover, it minimizes energy consumption as well as your electricity bills. The efficient use of technology is always a money saver. On the Con side, not all bulbs are suitable for the dimmer switch. So, either you must have one that is supportive beforehand or have to buy a new one.

How to replace a regular switch with a Dimmer switch?

Whether your switch is damaged or you wish to convert it to a dimmer switch, the procedure, precautions, and tools needed to get the work done remain the same. Firstly. We will look into the tools that we will need to replace the light switch with a dimmer switch. The list is given below. 

  • A Screwdriver
  • A Needlenose plier
  • Wire stripper
  • A Voltage tester
  • The Dimmer Switch
  • Several wire Caps 

Once you have all 6 of these arranged, it's time we look into precautions.


There are basically two precautions to highlight in this case.

  • Before you start any work, make sure that the power to your light switch is turned off.
  • You might still have power due to a wire malfunction. So, even though you have turned off your switch, use a voltage tester to be double sure that the switch has no power.

Replacing a Regular switch with a Dimmer switch

Now, let us look into the procedure of replacing a regular switch with a dimmer switch.

Open the Switch's Terminal

Firstly, unscrew the 3 or 4 terminal screws on the side of the switch, and then pull it open. You will find either 3 wires or 4 wires, depending on the switch.

For a single pole switch, you expect 3 wires: a black wire(hot wire) leading back to the power source, a black/ red wire leading back to the light fixture, and a green ground wire. For a 3-way switch, you expect 4 wires- a black wire(hot wire) leading back to the power source, 2 black/ red wires leading back to the light fixture, and lastly, a green ground wire.

For safety reasons, mark the hot wire with red tape before proceeding to the next steps.

Unscrew the Terminals

Use a screwdriver to turn all the terminal screws clockwise until it becomes loose. After it is loose, unhook them.

Connect the Green Wires

The green wire of the dimmer switch and the green wire from the terminal must be merged. Bring the wires next to each other and twist them with needle-nose pliers. Lastly, put wire caps over them.

If they have screws, loop the green wire around the screw and tighten it with a screwdriver.

Connect the Hot Wires Connect

The hot wire of the dimmer switch and the green wire from the terminal must be merged. Bring the wires next to each other and twist them with needle nose pliers. Lastly, put wire caps over them.

If they have screws, loop the hot wire around the screw and tighten it with a screwdriver.

Common and Traveler Wires for a 3-way Switch

This is for a 3-way switch only. With your pliers, hook on the end of the taped wire and loop it around the black common terminal screw. Hook 1 traveler wire that is red or black onto each of the brass terminal screws. In the end, tighten all the screws with a screwdriver.

Reattach the Switch & Turn ON the Power

Now, push back the wires into the electric box and position the switch accordingly. Make sure ON is located at the top. Secure the mounting screws back on the switch. Please find more details in How to wire a dimmer switch.

FAQs of replacing a dimmer switch

Can I change a dimmer switch myself?

Most dimmers are designed to fit a standard wall box opening, which makes it easy to replace the switch for any incandescent or halogen light with a dimmer.

Why does my dimmer switch have 2 black wires?

The two black wires connect to the black lead to the switch supply power to the switch/dimmer. The blue wire from the switch connected to the other black wire is the switched-hot going to the light.

What happens if you don't ground a dimmer switch?

When you don’t ground a dimmer switch, you put your body at risk of completing a circuit holding lethal electrical charges.

Are red and black wires interchangeable?

Yes, red and black wires positions are interchangeable.

How can you tell if a light switch is grounded?

If you place the neutral probe on the screw on the front of the faceplate or into the third-prong on a three-prong outlet, a properly grounded outlet will still light up the tester. If the grounding test does not produce light in the tester, the outlet is not properly grounded.
