Types of Dimmer Switches
When shopping for a dimmer switch, it’s important to understand the different types that are available on the market. You want to make sure you’re buying one that’s compatible with the light fixture it will be controlling.
The pole of a switch refers to the number of terminals it has. A single-pole dimmer switch features two terminals that turn one circuit on or off. This type of switch will not work for lights controlled from more than one location, such as a hall light with a switch at the bottom of the stairs and another at the top of the stairs.
3-Way and 4-Way Dimmers
Dimmers that are 3-way include three terminals, while a 4-way switch has four terminals. These extra terminals allow you to loop more switches into the circuit. For example, you need a 3-way dimmer to control a light with two switches. A light controlled by three switches requires a 4-way dimmer. When using a 3-way or 4-way dimmer switch, you should have only one dimmer switch on the circuit.
Unlike conventional dimmer switches, a multilocation dimmer switch allows you to have multiple dimming controls on the same circuit in more than one location. This type of dimmer works with 3-way switches, other compatible dimmer switches, remote controls, and smart home systems. In this setup, any device on the circuit is able to control the intensity of the lights. This is a good option if you’re using a smart dimmer to add voice control to your lighting but also want the option of using a manual dimming switch. A multilocation dimmer can have as many as nine additional dimming devices connected to it. This type of dimmer includes a manual on-off switch and dimming control at the switch.
Plug-in dimmers allow you to add a dimming feature to lamps and other lighting fixtures that plug into a standard 115-volt outlet. This type of dimmer plugs into a standard outlet. When you plug the lamp into the dimmer, you can dim the lamp by connecting the device via Bluetooth to a smartphone, Alexa, or another smart device. Once connected, you can use voice activation to control the lights.
What to Consider When Choosing the Best Dimmer Switch
How the switch operates, the type of bulb it uses, and its wattage capacity are just a few things you need to know about your home and lighting situation before you can determine which dimmer switch will meet your needs.
There are a variety of options to choose from when it comes to how you operate a dimmer.
- Rotary: A rotary dimmer features a round knob that you press to turn the light on or off and rotate to adjust its intensity.
- Toggle: This type looks like a standard switch and includes a small slider next to the switch that dims the light.
- Rocker: With a wide, flat on/off button that “rocks” on or off depending on which end you press, this type of switch offers a more understated, modern look. As with a toggle switch, a small slider next to the button adjusts the intensity of the light.
- Tap: A tap dimmer switch consists of a small flat panel that you tap with your finger to turn the light on or off. A small rocker switch to the side of the panel allows you to dim the lights.
- Scene selector: This type of dimmer allows you to control all the lighting in one room from a single dimmer, creating layered lighting for different looks or scenes to suit activities ranging from taking a nap to cooking dinner.
Dimmers will work with incandescent, halogen, LED, and CFL bulbs; however, you need to make sure the specific bulbs you use are compatible with dimmers. While most incandescent and halogen bulbs will work with a dimmer switch, not all LED or CFL bulbs will. Make sure you use an LED or CFL dimmer bulb; otherwise, you may get flickering or buzzing at lower intensities. Using a standard CFL bulb with a dimmer will shorten the life of the bulb and may damage the dimmer.
LED and CFL dimmer bulbs offer excellent energy efficiency and perform well on a dimmer. The disadvantage is they may not have as low a range as incandescent bulbs. CFL bulbs, for example, will dim down to only about 20 percent of their total light output. LEDs will dim to only about 30 percent, but some dimmers designed specifically for LEDs offer a better range. Incandescent bulbs have excellent dimming properties, allowing you to dim them to very low levels. The downside is they are much less energy efficient and produce a significant amount of heat.
Before purchasing a dimmer switch, first determine the wattage capacity it has to handle. Dimmer switches all have ratings that tell you their maximum watt capacity. For example, a dimmer switch may have a capacity of 250 watts for LED and 600 watts for incandescent bulbs. This means it can hand up to fifty 5-watt LED bulbs or ten 60-watt incandescent bulbs. Be sure to calculate the total wattage of the lights that are in the space the dimmer will control, and make sure the dimmer can handle the load.
Add lights to the growing list of things you can control with a smartphone. Smart dimmers can connect to iOS, Alexa, Google, and Android devices, allowing you to control your lights from your phone, via voice command from the comfort of your couch, or even from hundreds of miles away. You can also use this technology to program your lighting to dim or brighten automatically, depending on the time of day.
Although it may seem like a daunting job, installing your own dimmer is relatively simple and requires nothing more than a screwdriver. Most dimmer switches come with detailed instructions about how to wire the new dimmer switch once you have removed the old one. As is the case anytime you are working with electricity, it’s crucial to follow certain safety protocols. Always shut off the breaker to the circuit you’ll be working on to eliminate the risk of electric shock.

FAQs About Dimmer Switches
If you still have questions about dimmer switches, read on to learn how they are installed and whether they’ll save you any money on electricity.
Q. Do dimmers save electricity?
Dimmers save electricity by reducing the amount of power that flows to a bulb, allowing it to operate while using less energy. This lower power output also puts less stress on the bulb, leading to longer bulb life.
Q. Can you put any light on a dimmer switch?
You cannot put just any light on a dimmer switch. You need to check the compatibility of the dimmer switch to ensure it can handle the wattage of the bulb you have. LED and CFL bulbs also need to be dimmer compatible in order to work properly with a dimmer switch.
Q. How do you wire a dimmer switch?
Once you have removed the old dimmer, straighten the exposed wires so you can attach them to the new dimmer. Connect the bare copper or green ground wire to the box. Connect the house wires, which may be black, red, or white, to the wires from the dimmer box using wire connectors, making sure that no bare wire is exposed.
Q. How do you replace a dimmer switch?
Begin by turning off the power to the light switch by turning the circuit breaker off in the fuse box. Then unscrew and remove the switch plate. Use a voltage tester to make sure there is no power running through the wires. Unscrew the dimmer switch from the electrical box and pull it out. Remove the wires from the old switch.
