Here’s how to repair a light switch if you’ve got 10 minutes.
You flip a light switch and nothing happens. And you just changed the bulb yesterday. What gives?
Do you really need to call an electrician? Maybe not. The easiest and least expensive solution could be to replace the switch altogether. Best of all, you won’t need a $90-per-hour (or more!) electrician — it’s an easy DIY job.
How Much Do Switches Cost to Replace?
A single-pole light switch costs less than $6 to replace. Go for a rocker switch that’s easy to use and adds sensible universal design to your home.
Three-way switches let you control the same light from two different locations. When you flip one switch to the on position, the other switch is simultaneously moved to the on position. A three-way switch also will cost less than $6.
Likewise, four-way switches let you control the same light from three or more locations. Each four-way switch costs in the $10-$15 range.
Double-pole switches have four terminals instead of two, so they’re used for outlets and appliances that require 240-volt circuits. They also come in rockers. Each double-pole switch will cost $7-$15.
What if I Want a Dimmer?
Dimmer switches not only add instant mood lighting to a room, they save energy, too — for every 10% you lower a light bulb’s brightness, you’ll double the bulb’s life.
The only hitch: CFLs often don’t work with dimmers, so you’ll have to use LEDs or halogen incandescents in your fixtures. Dimmers come in rotary, slide, touch-activated, or digital varieties; the cheapest is rotary and will cost less than $10.
So How Do I Replace My Light Switch?
It’s easy. All you’ll need are:
- Phillips-head screwdriver
- Flathead screwdriver
- Voltage tester
- Needle-nosed pliers
Important: Before you attempt any repairs, cut power to the light switch by switching off the circuit breaker at your electrical service box.
