Digital timer switches offer more programming options.Controls the light switch with a timing mechanism.Dawn to dusk lighting turns light on when natural light is reduced.Uses a rotating knob, sliding lever, or one or more push buttons to increase or decrease electric current traveling between the switch and the light.Adjusts light brightness level up or down.Used in combination with 3-way switches.Controls 1 light from 3 or more locations.May control two 120-volt fixtures from one switch, such as a light and a fan.Controls 2 lights, one from each switch.Light switch prices by type Light switch type Installation is similar to a standard switch, but most smart switches require a neutral and ground wire. The smart switch alone costs $20 to $100+ and allows control and programming from a smartphone or other smart device. Smart switch installation costs $80 to $250+, depending on the type. Installation requires cutting two new holes and running wire to each switch. 3-way switches install in pairs, allowing light control from two locations. Installing a new 3-way switch costs $200 to $450 on average. Replacing a standard switch with a 3-way switch costs $160 to $300 total. The cost to replace an existing 3-way switch is $70 to $200 per switch, including labor and materials. Confirm the home's current electrical setup or consult and electrician to select the best timer switch type for the application. Just like dimmer switches, some timer switch installations require a neutral wire. Timer switch installation costs $80 to $200 on average, depending on the type and wiring required. Newer model dimmer switches are more energy efficient, reducing electricity use when used below full brightness. Use a 3-way dimmer switch when two switches control the same light.Ĭhoose a universal dimmer to ensure the unit works with any light bulb type as not all dimmer switches and light bulb types are compatible. Use a single pole dimmer switch for a light controlled by one switch. Check the current wiring or have an electrician determine the best dimmer switch type for the home's electrical system to avoid additional installation costs. The cost to install a dimmer switch is $80 to $200 on average for labor and materials. *Most electricians have a $75 to 125 service call fee and charge a one-hour minimum rate. Replace all light switches & outlets in a house Twist the bare ends together and cap the ends with a wire nut.Replace double, 3-way, or 4-way light switch Next, cut and strip the insulation from the ends of each of the grouped wires. Take and group the rest of the like-colored wires coming from the wall box, bare wires with bare wires or white with white as needed only the hot wires should be left without a group. Place a strip of electrical tape around the hot wires so that you can identify them easily later. ![]() In a double light switch setup, you will have multiple wires including one set each light fixture and one set that goes to the breaker box. A wire that is bare, green, or yellow (or green with a yellow stripe) is the grounding wire, and the white wire is the neutral wire. The hot wire is usually red, but can also be black. There are hot wires, neutral wires, and a grounding wire in nearly all electrical wiring. If the current is not present, you can continue. Press the contacts to each wire and each space between each wire. Then, the circuit tester to make sure the current is actually turned off. Before you start working, put the grounding strap on and connect the other end to the bare metal in the box. Use a screwdriver to remove the screws that are holding the switch's faceplate in place. If the box isn't properly labeled, turn the main power off for safety. If you're lucky, the breakers in the panel will be identified, so you can easily switch the power off to the area you're working in. Locate the main electrical panel that feeds the entire home. It doesn't matter if you're wiring something simple like a double light switch or as complicated as a junction box, as the seriousness is the same. Working with electricity is not something to take for granted if you're not careful, you can be seriously hurt.
