Wiring a 2-Way Switch
How 4-way switches work -- an animation
- Those answers should get you going, but I think your problem was in assuming that the positions of the screw connections on the new switch were the same as the old switch, which ain't necessarily so.
- Check to be sure the traveler wires only connect between the traveler terminals on all the switches.
- One note about this procedure, if you are dealing with a smart electronic switch or timer, the internal circuitry can not be tested in this way.
- Here I will try to describe a bit of what the color coding is about, and how wires should be colored in lighting circuits and why.
Cookies make wikiHow better. In the above picture, white is always neutral, while black or red may be hot. If you find travelers using white wires, use colored tape to mark each one in each junction box or device box where you find it, so that it will not be incorrectly viewed as a neutral wire. The previous figure shows a circuit that follows this convention.
Flip the switch toggle one way and then the other. If the light is located between the middle two switches, then the white wire leading from the light to a switch is, in fact, sometimes hot. Picture the letter Y, the hot conductor goes on the bottom, the travelers on the top. Are you sure you want to delete this answer? This red wire is the one that will supply power to the light after traveling through all of the switches.
Verify the circuit is wired correctly using the following guidelines. In the time it will take you to figure it out, you could have paid for a licensed electrician to do it without mistakes. Should I pour ammonia down a sink drain, then follow with bleach to unclog it?
There is a red wire in the boxes. Do not overlap the wire with itself beneath the screw terminal. If you have existing switches that stop working, dating they may be worn out or the terminal screws may have loosened over time. Find the wires connected to the two traveler terminals.
What if you want to control more than one light? The switches must create a complete circuit for current to flow and the bulb to light. Connect the traveler terminal between all the switches.

The other two screws, usually a lighter brass color, are known as the traveler terminals. Collin, from Grand Rapids, Michigan Thank you for answering my question. Light does not work correctly. Three-way switches can be wired in a number of different ways, free dating sites depending on where they are located relative to the light fixture in the circuit cable runs.
By marking the wire as above, you are informing anyone working in the box later that this is the wire that will deliver occasionally volts to the switch. Is it possible to wire the four way switch to work like a single pole? This one-minute animation is the clearest illustration of the function of three- and four-way switch function.
How to Wire a 4 Way Switch (with Pictures) - wikiHow
Note that wiring configurations can vary greatly depending on how the circuit is arranged. If a neutral wire is required at each switch location, a different configuration will be required, as shown in the video. Turn off that circuit breaker. Flip the switch toggle and check that you find continuity in one direction but not the other.
4 Way Switch Wiring with Light First
- The same way you would wire one light fixture with two switches.
- If the connections are made with clamps instead of screws, tug firmly on the wires to be sure they are all still tight.
- Or, as shown here, they can be wired so that the cables run through both three-way switches, then to the light fixture.
- Use pliers to twist the exposed ends of the two black wires together.
- Physics Miscellaneous tips and info Rick Matthews.
- The white wire of the cable going to the switch is attached to the black line in the fixture box using a wirenut.
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. Three-wire cable runs between the light and all the switches. If you have an old or new switch you believe was wired correctly and the circuit still doesn't work, the switch may be defective. One switch turns it on and the other will work only if you turn the original back off.
Top of page Wiring Switches. Next, connect the white wire coming into the box to the white wire on the fixture. The black and red wires running between the switches are all used as travelers in this arrangement. Did this article help you? That's all a regular switch is doing, breaking the continuity between your source power and your load.
Click the next switch to turn off the light. Click here for an overview of all these pages. If the switch box is metal, it also must be pigtailed to the grounding wires. Such markings are not needed with this type of switch, as they are with a single-pole switch. If you really think about it, you could not possibly have put all of the wires back in the exact same places, or the light would work just fine.
If you place a light in such a location, please be aware of the confusion that can occur from this wire color. Since the first failure I've changed the wiring enough that I don't remember the original set up. If the device is still lit up or working, boards the wrong breaker was opened.
Electrical Tips to Help You Wire it Right
If you find no continuity or constant continuity in any of the possible arrangements when you flip the toggle, the switch is likely defective. If you have two three ways, then the travelers run from one to the other and no where else. If, however, you don't find any continuity or constant continuity no matter where the probe is or how you flip the toggle, the switch is likely defective and should be replaced. This will enable the worker to properly wire replacement switches.
You can test the switches using the procedure described below. Does it have continuity now? Double-check that all connections are proper before carefully packing the wiring and switches back into each switch box.
Installing Dimmers for 3 Way and 4 Way Switches
4 Way Switch Wiring Diagrams
The white wire becomes the energized switch leg, as indicated by using black or red electrical tape. This wiring shows the light fixture and the electrical source together in the same box located between the switches. Wrap the wire nut connection with electrical tape for safety and durability. If you believe your circuit is wired correctly and the lights still don't work, one or more of the switches may be defective. The white wire is marked with black at each splice to identify it as hot.
In these cases, you can test the internal functionality with a simple procedure. Complete the connection by screwing a properly sized wire nut onto the joint tightly. You have given me confidence to do my own projects which I never had before. 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.
