Toggle Switches

Toggle switches are a type of electrical switch that is turned on and off using a lever. The lever or handle can be flipped up or down to control the flow of electrical current to turn on the light. They are the most popular type of switch among the rest. The average price for it is between $2 and $12.

Dimmer Switches

Dimmer switches, also known as “dimmer controls” or “selector light switches,” allow you to control the different light illumination levels in a room. The circuit allows you to dim or brighten the lights using the dimmer switch. Having a dimmer option helps the light bulb last longer, meaning they do not have to be replaced as often. Dimmer switches can save you money on utility costs. Their average price is between $10 and $25.

Smart Switches

Smart switches use programmable and Wi-Fi options that allow you to turn your lights on and off using a smartphone app. These switches are hardwired with your existing home lighting and are usually controlled using a switch or button. Some smart switches give you the option of dimming your lights, which reduces your energy usage when lowering the brightness. The average cost is between $20 and $40.

Type of Toggle SwitchCost per Unit (Only Materials)
Rocker switch$10-$12

Single-Pole Switch Price

Single-pole switches are very simple, common light switches. These units control one circuit and one light from a single location with two terminals. Most single-pole systems in a home tend to be single pole light switches. This type of toggle light system is the least expensive and ranges in price between $2 and $5.

Four-Way Light Switch

A four-way switch is very similar to a three-way type, except with four terminals instead of three. This type of unit has to be combined with two three-way switches to form a full circuit. Four-way light systems are the least common type, and if present, they would be found in larger rooms with multiple switches and entry points. The average cost for a four-way light switch ranges between $5 and $7.

Double-Pole Switch Price

A double-pole switch is very similar to a single-pole switch but has four terminals instead of two. These toggle switches can control larger voltages, such as 240 volts. Double-pole switches are commonly found in factories. You can expect to pay between $7 and $9 for a double-pole switch.

Three-way Switch Price

A three-way switch allows you to control a single circuit from two separate locations. These switches are commonly located at the top and bottom of a stairway or next to doors in a room with two entry points. A three-way switch allows you to use two light switches to turn three terminals on or off. These switches average in cost between $9 and $11.

Rocker Switch Price

A rocker switch is an alternative toggle switch that features a broad lever and can be activated using a “rocking” motion. These switches are considered decorative as they lay flat against a wall. Rocker switches are often seen as the main power supply on electronic devices as an on and off switch. These switches are single-pole with three-way options and range in price between $10 and $12.

Dimmer Switch Cost

Dimmer switches, also referred to as “selector light switches” or “dimmer controls,” allow you to change the brightness or dimness in a room by increasing or decreasing the bulb’s voltage. These switches are increasing in popularity and offer many advantages. They increase the longevity of the light bulb and save money on utility costs. There are three different dimmer switches, including rotary dimmer switches, slide dimmer switches, and light dimmer switches. The average price for a dimmer switch ranges between $10 and $25. The table below lists the different dimmer switches available and their cost per unit, not including installation fees.

Dimmer Switch Cost

Type of dimmer switchCost per unit (material only)
Rotary dimmer switch$10-$12
Slide dimmer switch$12-$18
Light dimmer switch$15-$25

Rotary Dimmer Switch

Rotary dimmers are switches containing a knob/dial used to control the brightness of a light fixture. Rotating the knob/dial adjusts the light from a very dim, average glow level to the bulb’s full level of brightness. The knob/dial rotates from left to right, and most have a push on/off function. Rotary dimmer switches are the most common dimmer and average in price from $10 and $12.

Slide Dimmer Switch

Slide dimmer switches are similar to rotary dimmer switches but differ in the way they are controlled. Instead of rotating a knob or dial, a slide dimmer slides up and down or side to side to change the brightness of the lights. This dimmer may or may not have an on/off toggle button. The average price for a slide dimmer is $12 to $18.

Light Dimmer Switch Price

Light dimmer switches look very similar to a single-pole toggle switch. The main difference with a light dimmer switch is that it features a smaller, less prominent slider next to the toggle switch. Light dimmer switches are the best option for setting the brightness and leaving it. You can expect to pay between $15 and $25 for a light dimmer switch.

Smart Switch Cost

Smart switches feature programmable options and Wi-Fi options that allow you to control the lighting in an entire house with one button, whether you are at work, on vacation, or at home. These switches are controlled using a switch or a button. Some smart switches give you the option of dimming your lights, which can reduce your energy usage. The average price for a smart switch ranges between $20 and $40. The table below lists the different smart switches available and their cost per unit, not including installation fees.

Consult with a pro when installing a light switch

Cost to Install Light Switch

The installation process is relatively simple and quick if rewiring is not required. The process begins with shutting off the current to the room or location where the unit will be installed. An electrician removes the cover plate and tests the wires to make sure they are not live. Once the professional confirms the wires are dead, they unscrew the old switch, loosen the screws, pull it from the box nestled on the wall, and unhook the wires. If any damaged wires are present, the electrician replaces the exposed wire, wraps it around the new terminal screws on the new switch, pushes it back into the box, and replaces the plate cover. The power can then be turned back on and tested using a voltage tester to make sure it works.

Unless you are a licensed electrician, you should not perform this kind of installation yourself. This type of installation can be very dangerous because you are dealing with electrical components, so it is usually best to hire an electrician.

The average cost for an electrician to complete the basic electrical task of installing a light switch is $40 to $50 per hour. If wire replacement is unnecessary, the entire process is very quick and takes approximately 45 minutes to install one switch. The labor involved accounts for approximately $125 of the project’s final cost. The switch only costs $2 to $40.

Cost to Install Dimmer Switch

The process of installing a dimmer switch is very similar to the process of installing a simple toggle switch. The difference is the extra step of wire connection that can take a little bit more time and knowledge to complete. Dimmer switches are connected to the house by wiring rather than by screw terminals. The cost to install a dimmer switch is $75 to $100, with $10 to $25 of the final cost for the dimmer switch itself.

Light Switch Installation Cost Factors

When installing a light switch, you’ll need to consider all the associated costs. Besides needing a wall plate, you may also need some other things such as hardware, wiring, and upgrades to the switch itself. If one doesn’t already exist, then a switch box, screws, and wall plate will be required for the installation. The type of switch affects the cost of installation. There are simple toggle switches you flip up and down, and then there are smart switches you can program and run from your phone via Wi-Fi.

If you have old wiring or an electrical panel with less than the required voltage, then you’ll need to update the electric panel to cover the additional voltage. This update can be quite pricey and add to the total cost. If you are relocating a switch, an electrician will run wiring to the new location, close the hole at the old location, and create a new hole. This work adds additional expenses to the project.

If your light switch needs rewiring, you will have to pay additional fees at a price per linear foot of wire. An electrician might charge a higher hourly rate if wires are less accessible or hidden behind walls.

Light Switch Installation Prep Work

You can take some steps to prepare for the installation before the electrician arrives. First, if you are replacing an old light unit with a new one, it is important to make sure the new unit’s voltage matches the old one. It is essential to turn off the power to the light from your breaker panel. No power can be running to the outlet when the electrician installs the new one. Know what switch you want to use to install or replace your old one. Lastly, before installing, the electrician should be aware of the type of wiring. Some houses may not have electrical wiring that is up to code, and therefore the wires may need to be added or replaced.

Cost to Replace Light Switch

If you have a light switch that is giving you problems or no longer working, then it needs to be replaced. The cost of replacement will depend on the type of light switch. Switches with extra features like dimmers or smart characteristics will cost a little more than a standard light unit. You can expect to pay between $50 and $150 for a replacement.

Dimmer switch$75-$100
Smart switch$85-$150

Toggle Switch Replacement

Replacing a simple toggle switch is an easy process that takes a professional less than 30 minutes to complete. A toggle switch replacement involves turning the power off at the main circuit and unscrewing to remove the switch plate. The switch from the electrical box is then unscrewed and pulled out with the wires left attached. Your new toggle switch will be matched with the same-colored screw from the old switch, and one wire will be connected at a time. Once completed, the new wired switch is put back into the electrical box, screwed in, and then the power is turned back on. The cost for a toggle switch replacement ranges in price between $50 and $75.

Cost to Replace Dimmer Switch

Replacing a dimmer switch is very similar to the process of replacing a toggle switch. Dimmer switch replacement differs in the fact that dimmer switches are connected by wiring instead of screw terminals. Due to the extra step of wire connection, this process can take a little bit more time. The cost for a dimmer switch replacement ranges in price between $75 and $100.

Smart Light Switch Replacement

The replacement process for a smart light switch can be quite tricky and should be done by a trained electrical professional. The process is the same as a toggle unit replacement but becomes more complicated when securing the new smart switch wires to the old wires. The two wires or cables are connected using a wire nut that binds the wires together securely. The cost of a replacement is a little more expensive and averages $85 to $150.

2 Way vs 3 Way Switch

The difference between a two-way and a three-way switch is a two-way switch turns the lights on and off from one location only, while a three-way switch can turn lights on and off from two locations. Two-way units have an on and off button while three-way do not because there is no consistent on or off position. The on and off changes depending on the position of the second switch. Two-way units are commonly found in many locations in homes. Three-way units are commonly installed in long hallways or at the end of the stairway so that the lights can be turned on or off when approaching or at the end of the hallway. You can expect to pay between $7 and $9 for a 2-way switch, while a 3-way switch costs a little bit more and averages in price between $9 and $11.

Enhancement and Improvement Costs

Cost to Relocate Light Switch

Relocating is a fairly easy task for an electrician. New wiring will have to be run to the new location when relocating a light switch. The hole at the old location will also have to be closed up and a new hole will need to be created. With wires and labor for one switch, this costs, on average, $255.

Cost to Update Electrical Panel

An update to the electrical panel is required if you have old wiring or an electrical panel with less than the required voltage. While some panels have space for additional voltage, others need a new circuit and breaker added. The average cost for an electrical circuit panel upgrade is $1,500 to $4,000.

Rewiring a Light Switch

An electrician can make the process of rewiring easy. The rewiring process involves loosening the screws holding the electrical wires and disconnecting the wires from the switch itself. New wires are then installed on the switch and rewired until you have a working unit. You can expect to pay $6 to $8 per linear foot of wire.

Combination Switch and Outlet

A combination switch and outlet is a panel that consists of one of each. The outlet can be a standard plug or, if more advanced, a USB charging port. Combination switch and outlet panels are best installed in kitchens. The average price for one of these is $15.

Photoelectric Switch

Photoelectric switches contain a sensor that automatically turns the lights on and off at sunrise and sunset. The sensor detects objects by emitting a light beam (visible or infrared) from its element. These switches are great if you don’t want to set a specific on and off time. They can be installed inside and outside. The average cost of a photoelectric switch is $10.

Additional Considerations and Costs

  • Permits. A permit is not required to install a switch; however, some municipalities require you to get a new permit to install new electrical circuits. Consult your state or city before performing any electrical work to see what is required from you. Licensed electricians in the area will know whether a permit is required in your area or not.
  • DIY. If you are inexperienced, then it is recommended that changing a light switch is not a DIY project. If you must do it yourself, then it is extremely important to shut the breaker off and use a voltage check to verify that the power is off before you proceed. Wearing a grounding bracelet and rubber-soled shoes and using tools with rubber grips are recommended for safety purposes. Contractors and electricians often mark the price of materials up by 15%. Therefore, you can save some money by purchasing the materials yourself.
  • Unused light switches. If a light switch is unused, then there is a possibility that it could be dangerous due to old, torn wiring. Make sure the wires running to the switch are inactive using a voltage checker.
  • Electrical panel transfer switch. If you have a standby generator, then a transfer switch is needed on your electrical panel. A transfer switch is installed on the electrical panel and transfers the circuit from one load to the other by flipping the transfer switch to the generator. This keeps the power on during a power outage. One transfer switch in your home is sufficient and averages around $250 for a residential switch. Labor to install this switch is between $200 and $400.
  • Grounding. The current code requires any new light switch installations to be grounded, but older switches don’t need updates if you are only replacing the switch and not the wiring. Not all light units require a grounding, but having one grounded in each room is beneficial as it prevents the circuit from overloading the entire house.


  • How much does it cost to fix a light switch?

You can expect to pay between $50 and $150 for an electrician to fix a light switch.

  • Do I need an electrician to replace a light switch?

Hiring a knowledgeable electrician to perform these tasks is recommended.

  • Can you put a dimmer on a three-way switch?

Yes, you can put a dimmer on a three-way switch. With a three-way dimmer, you can control a light with two switches.

  • How high should a light switch be off the floor?

The ideal light switch height is 48 inches from the floor.

  • Can a faulty light switch cause a fire?

Yes, a faulty light switch can cause a fire. If the circuit in the switch is hot, it can cause resistance leading to heat that results in a fire.

  • How long does it take to install a light switch?

The entire process of installing one, without replacing wires, is very quick and takes approximately 15 minutes to complete.

  • What is the difference between a switch and a light switch?

A switch is a device that makes or breaks the connection in an electrical circuit. A light switch is a switch that turns on and off the electrical circuit for a light.
