ated: May 27, References. When you want to switch electrical devices lights or other outlets on or off from two locations, you use a pair of 3-way switches. To switch from three or more locations, you will need to add 4-way switches. For example, you may want to control a ceiling light in the basement from the top of the stairs, from the bottom of the stairs, and from a door leading to the outside. This is not as complicated as it sounds, but when working with electrical wiring, you will want to know how to wire a 4-way switch easily and safely. You may add a 4-way to two 3-ways, if they are already installed. Then, connect the black wire coming from the fixture to the black wire going to the first 3-way switch.
Note that a 3-conductor cable is often used for connecting 3-way and 4-way switches to each other, containing black, white and red conductors. The white conductors should be marked to identify their function as travelers e. Other installers prefer to use two-wire cables from each switch to the next, purely for the travelers, and to run the hot or switched hot a different route to and from the fixture.

Some 3-way switches may have the "common" terminal on one side and the two "travelers" on the opposite side. Just make sure your black "hot" wire goes to the "common" terminal. Part 4 of Attach the red wire entering the 4-way switch box from the first 3-way switch box to the red wire going to the next 4-way switch. Some 4-way switches may have the "in" and "out" pairs opposite each other, rather than top and bottom.
Look at the markings on yours and read the instructions carefully. If you are adding more 4-way switches, repeat these steps with the two 3-conductor cables entering each 4-way switch location from the adjacent switches. Part 5 of Attach the red wire entering last 3-way switch box to the common "com" pole of the 3-way switch.
Not all 3-way switches are designed the same way. Just make sure the traveler wires are not connected to the common pole of the switch. Part 6 of Perform final assembly of the switches and wiring into their boxes. Many electricians use electrical tape to make a final wrap or two around each switch to cover the screw terminals prior to installing the switches into their boxes.
This is intended to reduce the risk of accidentally shorting things to the terminals. Double-check that all connections are proper before carefully packing the wiring and switches back into each switch box. Screw the switches into their boxes, being careful not to nick or pinch any wires. Test all of the switches. There are 8 possible combinations, when using three switches on and off.
How To Wire A 3 Way Light
They should all function properly. The same way you would wire one light fixture with two switches. There are many ways to wire a 3-way switch. Once you pick which one matches yours, you just replace the diagram with 2 lights instead of one light.
Not Helpful 2 Helpful 1. I wanted to buy a single-pole switch of a specific color. I did find a 4-way switch with the color I wanted. Is it possible to wire the four way switch to work like a single pole? If you have a multimeter, use the continuity setting. Pick one of the four posts of the 4-way switch to hook up the source power.
Put one lead of the multimeter on this post. Test the other posts to see which one has continuity and which does not. Leave the lead on a post that does not have continuity with your initial post. Now flip the switch.
How do you hook up a three way switch
Does it have continuity now? All you have to do is use two posts of your 4-way switch that alternate continuity when you flip the switch. That's all a regular switch is doing, breaking the continuity between your source power and your load.

Install A Three-Way Switch
The 4-way switch may be placed anywhere in the system. In any case, as long as you realize that only the two "travelers" between 3-ways are switched by the 4-way, you should be able to figure out the rest. Hint: Two travelers from one 3-way are connected via the 4-way to the other 3-way, without connecting to anything else.

You can add any number of 4-way switches to this circuit as long as you install only 4-way switches "between" the travelers of two 3-way switches. Helpful 0 Not Helpful 0. After you have turned off the circuit breaker, cover the switch with a strip of electric tape, so no one in the household is tempted to turn the breaker back on without your permission.
A green or bare wire is the grounding wire, and it should be attached to a ground pole of each switch, usually a green screw, and to each box when using a metal box. Bare wires should be twisted together and wire-capped to provide grounding continuity to all switch locations.
Some local codes may not allow the use of non-metallic-sheathed cables other than in single-family dwellings. The ground wire goes through both switch boxes and the ceiling light box and it is connected at all junctions, except the light, with a pigtail short piece of wire and wire connector. The hot wire in the drawing is black and is connected to the COM terminal. The neutral wire is white. Track each with a finger to its conclusion at the light fixture to ensure proper connection.
Some light fixtures with a chain pull have a ground connection.
Understanding Three-Way Wall Switches
Option 2. Fixture Controlled by Two Switches: Power Through Light Two three-way switches control one light with the electric power coming through the light on a two wire cable. In order to code the white wire, which is used as a power wire from the light fixture through the switches, black electrician's tape is wrapped around the wire in the boxes. This way, if you or someone else goes into the boxes for repairs, the white wire taped black will indicate a hot wire.
Even when taped black, the white wire may never be used to bring power to the fixture terminal. The red traveller switch wire runs just between the two switches, not the light. Note connections of the ground wire. Click Image or here to enlarge Diagram. Option 3. Fixture Between Two Three-Way Switches: Power Through Switch Light is controlled by two three-way switches with the light between the switches and the power first going through a switch, then to the light, and onto the second three-way switch.
The ground wire is pigtailed with a wire connector at the switch boxes and the ceiling box. Grounding screws often are furnished with boxes and are green.
Tip:The traveller wire goes through the light ceiling box and that the white wire is taped black between the fixture and second switch. Option 4.
Three-wire cable with a ground wire is used for this connection. The power is routed first through the light ceiling box and then flows to the switches.
Tip:White neutral wire from the power source is connected directly to the light fixture. The black or hot wire is routed to a switch and then is fed back through the connections via a white wire taped with black electrician's tape to indicate that it is hot. The traveller wires are connected at the fixture box. Option 5. 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.
