The cost to replace a light switch is $150 on average, but it often ranges from $60 to $300, depending on the switch type and the cost of professional labor in your area.
Want to light up your home with new light switches? The average cost to replace a light switch is $150. However, you could pay as little as $45 or as high as $450. The difference depends mostly on the type: standard, double, dimmer, transfer, or timer switch. Learn more about the cost of installing a light switch, when to hire an electrician, and how to install a light switch.
A big cost factor is the type of light switch you choose. The more elaborate, the more costly. So, a standard switch is your least expensive repair, while dimmers and timers land on the higher side.
Type of Switch | Average Cost |
---|---|
Standard | $1–$20 |
Double | $10–$20 |
Three-way | $3–$15 |
Four-way | $10–$25 |
Dimmer | $10–$25 |
Timers | $20–$150 |
Smart | $20–$100 |
Manual transfer | $100–$800 |
Automatic transfer | $300–$2000 |
A single light switch is the standard “on and off” switch that controls one light fixture. Depending on your electrician, a simple light switch replacement can cost between $50 and $150. It’s the easiest switch to replace. This price is based on an electrician’s average hourly charge of $50 to $100 per hour.
Double light switches operate two items. Three-way switches power one fixture at two locations, and four-way switches operate one fixture from three locations. They require slightly different wiring than a single switch and are a bit more expensive to replace. A typical electrician will charge between $75 and $175 for this repair.
A dimmer switch can give you a range of illumination. However, these switches do require more time to install than standard switches. They usually run between $80 and $200.
Timer switches allow you to set lights to a schedule. Timer switches don't cost much more than a dimmer switch, typically between $85 and $200.
Like dimmers and timers, smart switch installation runs between $85 and $150 nationally. Note that this is the switch only. If you are doing hardwiring of smart devices, lights often come in a package deal with items such as outlets.
Transfer switches are installed near the main breaker of your home and direct power from a portable or standby generator to select appliances. Professional installation of a transfer switch averages $200 to $400. This is based on an electrician’s average hourly charge of $50 to $100 per hour, since this is a three- to four-hour job.
The location of the switch will be a factor in the cost. The residential units range from $100 to $800 for a manual and $300 to $2,000 for an automatic.
Before you change to a different switch, check to make sure it is compatible with the type of light fixture you have.
If you DIY replacing a light switch, it will save you the $50 to $100 per hour cost of an electrician. As long as you take the necessary safety precautions, changing a straightforward switch should be a simple DIY project.
To do the job yourself, you will need:
The new switch (see above for average costs)
Phillips tip screwdriver
Standard slotted-tip screwdriver
Work light
Voltage tester
Continuity tester
Needle-nose pliers
Wire strippers
You can also DIY a dimmer switch, but it is recommended that timers and smart switches be installed by a local licensed electrician.
A popular add-on when changing out light switches is replacing outlets. Since you will have the power off and all the tools at the ready, it will save time you might take later to install an upgrade. Another idea is to install a new light fixture or ceiling fan. Again, you already have the tools you need and the power off. The only thing missing is the new fixture.
