How to hook up a light switch with 3-way light, how to wire a basic 3-way switch
Two terminals will be on one side of the switch housing; one terminal on the other side. The red traveller switch wire runs just between the two switches, not the light.
Twist the stripper or rotate it degrees, sliding the insulation off the wire as it breaks loose under the cutting blades. Although it is referred to as a 3-way switch, it has four positions, off, lamp one lowlamp two mediumand lamps one and two high. In some cases, it may run through the electrical box where the existing light is installed, but it is only a switch wire and not a wire for the light.
The neutral wire is white. Grounding wires are pigtailed to the light fixture boxes, and to the switch box terminals.

Be sure the circuit is completely dead! If not marked, the common terminal may be color-coded black or brass. With a sharp knife or slitting tool, slit the outer sheathing, being very careful not to cut the insulation covering the wires inside the cable.
Power Through Light End-wired lights are controlled with two three-way switches with power routed through the light boxes to two-wire cable to the two switches. I will touch on one of dating socially awkward girlfriend most common and easy to follow methods.
The ground wire is pigtailed throughout.
Install A Three-Way Switch
A 3-way socket that is to be wired to a separate 3-way 2-circuit switch, is called a "keyless 3-way socket. To do this job, you would need 17 feet of cable. Fixture Between Two Switches: When they are both energized at the same time, W of power is delivered, and a high level of light is produced.
Most codes dictate that all wire connections must be placed inside a switch, receptacle or junction box. The traveller wires are connected at the fixture box. In the first box, splice the neutral white wire from the power supply to the white wire in the 3-wire cable going to the other switch. This way, if you or someone else goes into the boxes for repairs, the white wire taped black will indicate a hot wire.
Add an extra foot for every connection you will make along the line.
Neutral wire bypasses first three-way switch. The ground wire is pigtailed with a wire connector at the switch boxes and the ceiling box.
Fixture Controlled by Two Switches: Circuit diagram of a 3-way bulb. The two filaments can be activated separately or together, giving three different amounts of light. The cable should also have a ground wire, or a total of four wires in the cable.
If possible, lay the cable on a flat, firm surface to slit it properly. The wiring of a 3-way switch is something most DIYers are capable of doing.
The other black and white wires are the electrical circuit for the switch. In the following illustrations, track each wire with a finger or pencil to its conclusion at the fixture.
When working with electricity, always turn off the power at the main service fuse or circuit breaker panel before you start working. Most light fixtures have two electrical wires with colored insulation and a copper ground wire. The switches are wider than regular single-pole switches and they have three terminal screws on the side sometimes back of the switch housing.
End-of-Run Lights Controlled by Two Three-Way Switches These end-of-run lights are controlled by two three-way switches with a two-wire cable power source coming through the first three-way switch.
You may also use a cable ripper.
They support hot conductors traveller wireswhich receive and transfer electricity from each of the three-way switches. A 3-way socket has three electrical contacts. The 4-way switch is used in combinations with two 3-way switches when one or more lights are to be controlled from three or more locations.
In most cases, the nuts are the same color, such as red, yellow or black. It has a low-power 50 W filament and a medium-power W filament. The following article and detailed wiring diagram will hopefully clear up any confusion you might have about proper procedures for wiring that 3-way switch. Here is the procedure to follow: The 3-way switch is used in pairs when one or more lights are to be controlled from two locations.
Canadian code requires the use of 14 wire for interior application. Peel back the sheathing and trim it square. A 3-way incandescent bulb has two filaments designed to produce different amounts of light.
Attach the hot black wire to the common screw on the 3-way switch. To do this, the switch must be capable of operating two different circuits. Three-wire cable with a ground wire is used for this connection. White neutral wire from the power source is connected directly to the light fixture. Track each with a finger to its conclusion at the light fixture to ensure proper connection.
The traveller wire goes through the light ceiling box and that the white wire is taped black between the fixture and second switch. All of the four terminals are brass colored.
How to Hook Up a Home Light Switch
Note connections of the ground wire. The traveller wire is connected in the light ceiling boxes, with a length of neutral wire taped black to indicate a hot wire.
A "keyed 3-way socket" has the switch incorporated in the lamp socket and requires no external wiring between switch and socket.
The single-pole switch is used when one or more lights are to be controlled from a single location. Things You Will Need. One of the black and white wires goes to the light fixture.
Note that the shadings of the wires in the illustrations represent actual color. With wire strippers, put single wires in the proper size groove in the handle 12 for No.
The power is routed first through the light ceiling box and then flows to the switches. All wire is utilized this way without waste.
If wires going to switches and fixtures are going to be exposed to dampness, use wire designated for damp locations. Check the wires in the device box with the non-contact voltage detector.
