4 Way Wiring, Source at the Light
This diagram illustrates wiring for a 4 way circuit with the electrical source at the light fixture and the switches after. Two-conductor cable is run from the light and 14/3 cable runs between the switches. The hot source is spliced through to the second common terminal and the hot terminal for the light fixture is connected to the first common.
4 Way Wiring, Source First
In this diagram the source for the circuit connects to the first common. Three-conductor cable runs between switches and 14/2 cable runs to the light fixture. The neutral is spliced from the source, through to the fixture. The hot from the light is connected to the second common. The travelers run between the 4 way and the two 3 ways.
4 Way Wiring, Source and Light Center This wiring shows the light fixture and the electrical source in the center of the circuit. Three-conductor cable runs throughout and the hot source is connected to the first common terminal. The travelers are spliced at the fixture outlet box to run to the 4 way. The 4 way comes right after the light fixture but before the second 3 way, making it fall between the two 3 ways as needed. It could also be installed on the other side of the light and the effect would be the same.
Control Lights from Four Locations
Two 4 way and two 3 way switches are used in this circuit to control lights from four different locations. The hot source is at the first common and 14/3 cable runs between all switches. Two-conductor cable runs to the fixture and the light hot connects to the second common terminal. The two 4 ways occur between the 3 ways as needed and the traveler wires run from one switch to the next in the series.
4 Way Dimmer Wiring Diagram This is the wiring for a dimmer in a 4 way circuit. To make this circuit work, a 3 way dimmer is used in place of one of the standard 3 ways. A dimmer can be added in this way to any of the circuits on this page. These devices have 4 wires: one common, two travelers and a ground. The common wire is usually black and the travelers red, in any case, the traveler wires will usually be the same color to distinguish them from the common.
In this diagram the hot source is connected at the first common and 14/3 cable runs between the switches. The travelers run between the 4 way and the other devices and 14/2 cable runs from the dimmer to the fixture. The dimmer common wire is spliced to the hot terminal on the light.
About 4 Way Circuits A 4 way switch must be wired between two 3 ways as shown in the diagrams on this page. A 4 way has five connections, one ground and 4 circuit terminals divided into two matching pairs, sometimes called the input and the output. The terminal pairs may be different colors or they may be labeled to distinguish them from each other. Each pair of terminals should be wired to the traveler wires from one of the 3 ways. The travelers can be wired to either terminal in a pair but don't mix up the pairs or the circuit won't work properly.
Three way switches have 3 terminals to carry circuit electricity and one terminal for a ground wire. Of the three circuit terminals, one is called the common and the other two are known as travelers. The common terminal may be labeled and is usually a different color than the traveler terminals. Depending on the manufacturer, the travelers may be on opposite sides of the switch or the two terminals may be on the same side. In any case, the common terminal will be distinguished from the travelers in some way.
The common terminals will always be connected to a hot wire, either the hot source or the device hot. These connections can be reverse if it's more convenient, as long as one of the 3 way switch common terminals connects to the hot source and the other one connects to the hot on the load, these circuits will work properly. The traveler terminals will be connected from switch to switch. Travelers never connect to a device load or to a source wire. It doesn't matter which traveler terminals are used for which traveler wire, reversing them should make no difference.
About Wiring The wiring diagrams on this page illustrate 15 amp circuits using
14/3 cable between the switches and
14/2 cable to the light fixtures . Existing household wiring used for lighting and receptacles may be on 15 or 20 amps circuits. To use this wiring in 20 amp circuits use 12 awg cable and devices rated at 20 amps.
To avoid confusion the white cable wire should be marked with black electrical tape when splicing it to carry current. Ground wires should be spliced with at short piece of wire and connected to each device. If the light fixture box has a metal grounding terminal the ground wire should be connected there.
Troubleshooting All these diagrams have been tested in real life circuits but because of variable factors in existing wiring the examples displayed here may not work in every instance. To avoid problems make sure the hot wire from the source is connect to the common on one of the 3 ways and the hot wire to the fixture is connected to the common terminal on the other one. Aside from the ground wire, only traveler wires will be connected to a 4 way. If after wiring, you experience problems with the circuit, switching the traveler wires will most likely resolve the issue.
Alternate Wiring Diagrams
Wiring Multiple Lights Between 3 Way Switches
In this multiple light circuit, two fixtures are shown but more can be added by duplicating the wiring between the lights, for each one added. Note that the ground wire is not used in one of the two–conductor cables between the light fixtures. This wire can be capped or taped and folded to the back of the box out of the way.
Wiring Multiple Lights Before 3 Way Switches
This diagram illustrates wiring multiple lights and the source before the 3 ways. As with the other diagrams on this page, more lights can be added by duplicating the wiring arrangement between the fixtures.
Wiring Multiple Lights with a 4 Way Switch
This diagram shows the wiring for a 4 way circuit with the source and lights coming before the switches. As with all these circuits, the 4 way must be wired between the two 3 ways.
Wiring Multiple Lights with a 4 Way Switch, Lights Center
This 4 way wiring illustrates the source coming before the switches and the light between. The 4 way can be placed between, or on either side of the light fixtures, as long as it occurs between the 3 ways the circuit will work.
Wiring a Light and Receptacle
This wiring diagram illustrates the connections for 3 way switches to control a receptacle added to a lighting circuit. The hot source is connected to the receptacle and the common on one of the switches. The second common is connected to the hot on the light fixture. The neutral is connected to the receptacle and the fixture.
3 Way Switch Controls a Light and Receptacle This diagram is similar to the one above but both the light and receptacle are wired after the two 3 way switches.
About These Circuits A 4 way switch must be wired between two 3 ways as shown in the diagrams on this page. A 4 way has five connections, one ground and 4 circuit terminals divided into two matching pairs, sometimes called the input and the output. The terminal pairs may be different colors or they may be labeled to distinguish them from each other. Each pair of terminals should be wired to the traveler wires from one of the 3 ways. The travelers can be wired to either terminal in a pair but don't mix up the pairs or the circuit won't work properly.
