You can also add as many 4-way switches as you like in place of any one shown in the circuits that follow. All the 4-way switches are optional. Not to worry, you can purchase and oversize receptacle box just for such an occasion. With conduit, the wire colors for travelers could be any color. The white neutral wires are connected together in each switch box. The switches must create a complete circuit for current to flow and the bulb to light. The Right Box: This way, all the wires can be used with no waste. The diagram below will give you a good understanding of what this circuit is accomplishing. Diagrams shown on this page are simplified for clarity. Electrical outlet boxes can have numerous NM cables going in and out. Here is a typical circuit in its four possible states.: You can use as many 4-way switches as you like. For choosing wire color for your circuit, see later in this page.. Power to light -- splits to switch and to light -- light to switch This scenario gets a little tricky. This circuit also shows rough-in boxes, wire nuts, and proper color code. Red indicates a hot wire volts ac. Power to light -- splits to two 3 way switches Here is another example of wiring a 3 way switch with the power coming from the fixture. This option is helpful if you are adding a light to an existing building and it is easier to drop all the lines down from an attic instead of trying to get wiring up from a finished basement or trying to fish wire up two stories. The previous figure shows a circuit that follows this convention. As long as you keep this in mind, a 3-way circuit becomes really simplified. Note that the above color scheme does NOT reflect wire color. A 3-way switch is shown below. How wire 3 way switch



Option 9: Black and red are used for "hot" conductors volts with respect to ground. Option 6: Like the diagram above. When the left switch is toggled, it connects to the upper circuit and now the circuit is open at the right switch which turns off the light. The switches must create a complete circuit for current to flow and the bulb to light. It may be as shown at the end of the run, but it may be between any pair of switch boxes as shown in a later figure , or even between the panel and the first switch box. The colors will vary depending on whether NM cable or conduit was used. If you only need two switches, leave out both the 4-way switches. For choosing wire color for your circuit, see later in this page.. This circuit also shows rough-in boxes, wire nuts, and proper color code. If one switch is up and one is down, the current reaches a dead end, no current flows and the bulb is off top left and bottom left. You can use as many 4-way switches as you like. Note that the light can be placed anywhere in the return wire, shown above as white. In particular, it is often convenient and efficient to place a light between two switches or between the panel and the first switch. The diagram below will give you a better understanding how this circuit is wired. Be sure to check local building codes for proper installation and permits.

The traveler wires go from switch to switch connected to the traveler terminals, it doesn't matter which. All the 4-way switches are optional. When both switches are up, the circuit is complete top right. The lower left screw is the common and gets the black wire from the load 3-cond. It ties into the common on the left switch. With NM cable, the wire colors for travelers will be black and red using 3- wire cable. Option 6: The upper right screw gets the red wire from the right box 4-cond. In the first position, the contacts are connected straight through, so that the switch has no effect. If you're simply replacing a 3-way switch, the diagrams below will show the different scenarios on how your circuit could possibly be wired. The switches must create a complete circuit for current to flow and the bulb to light. No longer allowed after NEC if no neutral wire in switch boxes 3- Way Switch Wiring Diagram Light Fixture Between Switches Line voltage enters the first 3- way switch outlet box, light fixture is located between switch boxes. Here is one more variation, with the cable from the panel going directly to the light box, which is in turn between some of the switches.. Keep in mind that the maximum allowable wires in a standard size electrical box is five 5. In this option you will have seven 7 wires in the first box. If in doubt, hire it out. For choosing wire color for your circuit, see later in this page.. 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. Controlling a light with three or more switches For more than two switches, one or more 4-way switches are added between the 3-way switches. The upper left screw gets the red wire from the left box 4-cond. The previous figure shows a circuit that follows this convention.
