How should a 4-way switch be wired?
4-way switches are always wired in conjunction with two 3-way switches. That is to say that any time you find a 4-way switch, there will also be two 3-way switches controlling the same light fixture. 4-way switches are only used when there are three or more light switches controlling one light fixture.
Is there such a thing as a 4-way light switch?
A four-way switch is similar to a three-way, except it has four terminals (plus a ground terminal) and controls one fixture from three locations. This type of switch must be combined between two three-way switches to form a circuit. While more uncommon, this is a good option for large rooms with several entrances.

This has been a presentation of the four way switches.
How is a 4-way switch supposed to work?
There are four terminals that provide two sets of toggle positions on a 4-way switch. Each set of terminals is one of the toggle positions. When the switch is in the up position, the current can flow through two terminals. In the down position, the current flows through the other two terminals.
Why are there 4 wires on my light switch?
The black is the "hot" wire, the white is the neutral, and the copper is the ground. When you put a switch in a circuit you now have 6 wires - three coming in and three going out. Since the switch cuts the power on and off, there will be a black wire coming into the switch and a black wire leaving.
Can a 3 way switch be used as a 4-way?
A 4way switch will not work in place of a 3way. The common toggle (in), whether up or down on a 3way switch, comes in contact with both switch leg (out) terminals. A 4way switch will not accomplish this. The 4way is more like two "separate" single gang switches, they will not work in unison as one.
Is a 4 way switch double pole?
Double pole light switches, also known as a four-way switch, are two single pole switches put together. Two separate circuits are controlled by one switch. This is typically used to control a circuit from multiple locations in a series of three switches on one circuit.

What is difference between 3 way and 4-way switch?
For example, with a 3-way switch (such as the TM873W ) one light load could be controlled from up to two different locations. Whereas a 4-way switch (such as the TM874W) allows for control of one light load from up to three different locations.
Is black wire input or output?
4-way switches can be quickly identified by the 4 screw terminals (in addition to the green/gnd screw terminal). Two of the terminals are brass and labeled "input", the other two are black and labeled "output". It is very important to pay attention to these as shown in the 4-way switch diagram.
How do you test a 4-way light switch?
Four-way switch: Clip the wire of the continuity tester to one of the darker screw terminals, then touch the other wire to the lighter, brass-colored terminal on the same side of the switch. Flip the toggle lever back and forth: The test should show continuity when the lever is in one position, but not both.
Where are the black and white wires on a 4 way switch?
Attach the black and white/blue traveler wires entering the 4-way switch box to the "in" terminals, often the top terminals on the 4-way switch - black on the left top pole and white/blue on the right top pole. Some 4-way switches may have the "in" and "out" pairs opposite each other, rather than top and bottom.
How are two 3 way switches connected?
Two 3-way switches are connected to each other via "traveler" wires, only one of which is "hot" in any given switch setting combination. The 4-way switch connects in the "middle" of the two travelers. Each 3-way switch has a "common" terminal and two traveler terminals.
What color wire to use for a 3 way switch?
Connect the black wire coming from the fixture to a red or white wire that leads out of the box to the first 3-way switch box, and (if using white) identify the white wire with a color marking, such as red electrical tape.

How many poles are in a 4 way switch?
A 4-way switch has 4 terminals or poles. Two terminal/poles are labeled "in," and two are labeled "out.". Pairs of wires, called "travelers," will connect to each side. When the switch is operated, current will either travel straight through or crisscross.
How to check continuity on a 4 way switch?
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. 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.
What is the purpose of white conductors?
The white conductors should be marked to identify their function as travelers (e.g., the white with a blue tape marking). 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.
How many wires are in a 4 way switch?

What are the wires on a light switch?
The red and white wires from SW 1 are used as the travelers, at the light box they are spliced to the red and white running to the 4 way switch. The white wire is marked black on both ends to label it as hot. The black wire running to the 4 way is connected to the hot on the fixture and at the switch box it's spliced to the black wire running to the common on SW2. The red and white wires running to SW2 are used as travelers and again, the white is marked black on the ends.
How many wires are needed for a 4 way switch?
A 4 way switch must be wired between two 3 way switches as shown in the diagrams on this page. A 4 way switch has five terminals: one ground and 4 circuit terminals divided into two matching pairs called travelers. Each pair of traveler terminals should be wired to the traveler wires from one of the 3 way switches in the circuit. The travelers from one 3 way can be wired to either terminal in a pair, but don't mix up the pairs on the 4 way or the circuit won't work properly.
What are the black and red wires on a 4 way switch?
The black and red wires running between the switches are used to connect the travelers on each switch. Take note that the traveler wires from SW1 are connected to the T1 pair on the 4 way switch and the travelers going to SW2 are connected to the T2 pair.
How to check if a 4 way switch is a neutral?
Also, confirm that each pair of travelers on a 4 way are only connected to one switch per pair. Check that the neutral from the source is only connected to the neutral terminal at the load. A neutral wire will never be connected to standard 3 way and 4 way switches, although some smart switches and timers may make use of a neutral wire to operate the device. If you believe your circuit is wired correctly and the lights still don't work, one or more of the switches may be defective. You can test the switches using the procedure described below.
What is the common terminal on a 3 way switch?
The common terminal on the 3 way switch at the end of the circuit connects to the black wire running to the hot terminal on the light. Take note that the traveler wires from SW1 are connected to the T1 pair on the 4 way switch and the travelers going to SW2 are connected to the T2 pair. Each pair of traveler terminals on ...
How to test a 3 way switch?
To test a 3 way switch, connect one meter probe to the common terminal and the other to one of the travelers. Flip the switch toggle one way and then the other. If the meter shows continuity with the toggle in one direction and not the other, move the probe from that traveler terminal to the other one and test again. If you find the second traveler shows continuity with the toggle in one direction and not the other, the switch is probably functioning properly. 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.
What is a 3 wire dimmer?
Three-wire cable runs between all the switches and 2-wire cable runs to the light. To make this circuit work, a 3 way dimmer can be used in place of one, or both of the standard 3 way switches. In fact, a dimmer can be used this way in place of any of the 3 way switches on this page.
How to connect white wires to a 4 way switch?
Connect both white wires together with a wire connector and stuff them back inside the wall box. Take a spare 6-inch length of ground wire and connect it with the two ground wires in the box so you create a pigtail. Connect the pigtail to the ground wire on the four-way switch. Advertisement.
What cable goes between two three way switches?
There is a length of NM cable (ROMEX®) that travels between the two three-way switches. This line needs to be split at the point where you are installing the four-way switch. If the walls are already finished with drywall, it will be very difficult finding this cable. This job is preferably done in the roughing-in phase of remodeling, however, if you take your time and don't rush things, you should be able to track the cable down.
