3-way switch circuits — Variations

I do understand how to do a 3 way switch with one light, but want to be sure that I understand how to do it with just one more light. If you can help me, that would be greatly appreciated. For this reason it is so much easier to wire the circuit by taking power to the first switch, switch to switch, and then up to the light, and light to light. Will I need a separate power wire to energize that second switch??? Maurice The solution given is the best. In your method, someone seeing the wiring has no idea that it is a 3 way installation. The 3rd wire in this type of cable is insulated with a red jacket, which also aids in identification and safety. I have to admit that i sometimes get bored to read the whole thing but i think that your blog can be an exception. Andrew thanks for the help Jim If I have two switched connected for 3 way switch in my upstairs hall, does a third switch also have to be 3 way or can it be a single stand alone switch?

You need a constant hot and a neutral wire. It would be helpful if you can check what wires are in each location – what colors, and how many actual cables are coming in. You’ll need to turn off the power at the breaker panel and physically remove the switches don’t disconnect them, just pull them out , as well as the light fixture. There are several ways to wire 3-way switches, but what you’d be concerned with is the type where power comes to the switch first: In the above diagram ,you can add another switch to the one on the left – you’d connect to the white and black wires coming from the “power source” line.

On the switch on the right, you have a neutral, but you don’t have constant hot — hot is switched, on either the red or black, depending on how the first switch is flipped. Another common way the switches are wired is the power goes to the fixture first. In this case, there is no neutral at the switches. Also note, the black tape on the white wires indicates this. White is, by code, always neutral, and has to be marked if it’s used for a switched circuit.

That said — keep in mind that not everyone follows code. This still may not be possible, and definitely isn’t a beginner task – you need to understand electrical fairly well, and map out everything involved with this circuit.

Contact Author Wiring a 3 Way Switch Wiring a three way light switch is not a particularly difficult task – there are only 3 connections to be made, after all. Making them at the proper place is a little more difficult, but still within the capabilities of most homeowners – that’s where understanding a wiring diagram can be of help. To replace a switch is not difficult at all; simply put the wires back on the new light switch in the same relative position.

The problems arise when a new switch is being added, or the handyman forgets which wire went where. Then it is necessary to understand a little more just how a three way switch works, and perhaps how to read and understand a wiring diagram. There are many possibilities for methods of getting the proper wire to the proper place but in every case the actual wiring has the same effect and uses the same concept – if that effect and concept is known the task becomes much simpler.

This article is designed to explain these things for a better understanding of how to wire a 3 way switch, and wiring diagrams are shown for common wiring methods for these switches. Additional information is available in the article written on how to wire a 4 way switch , with additional wiring diagrams for these switches. How a 3 Way Switch Works The photos below show the back of a 3 way switch. There are 3 screw terminals on the sides of the switch, along with one on the end, and every switch will have the same three terminals.

The small screw terminal on the end is the ground terminal and is usually painted green, although the picture does not show that color well. It can often be recognized as the screw that is part of the metal framework of the switch and is not insulated from other metal parts. The green, or bare of insulation, ground wire always goes to this terminal.

Older switches often did not have this ground screw, but are no longer legal to use and all current light switches must have a ground screw to attach the ground wire to.

The following article and detailed wiring diagram will hopefully clear up any confusion you might have about proper procedures for wiring that 3-way switch. What Exactly is a 3-Way Switch? The 3-way circuit is a very common system found within most residential installations.

If the switch uses solder terminals, push the wires into the terminals and bend them back to hold them in place. Heat up the soldering iron until it is hot enough to melt the solder. Hold the soldering iron on the terminal and the wire at the same time.

Full Answer Before beginning installation of a toggle switch or other electronic component on a volt system, the individual should disconnect the power from the system. For most automobiles, the easiest way to accomplish this is by disconnecting the battery terminal. Once the power is disconnected, installers should consult the vehicle’s wiring diagram to determine the appropriate wire for installing the switch.

When replacing a toggle switch, vehicle owners sometimes encounter switches with four wires. On these switches, two terminal screws are one color and the remaining two another. Mark the wires before removing them from the old switch to determine which pairs of wires to match to the same color screws. In many cases, the existing wires are too short to reach the location of the new switch. Twist-on wire nuts allow splicing additional lengths of wires to the existing ones.

Wiring a 3-Way Switch

Most of the outlets in your home are of the duplex variety—that is, you can plug two devices into them at one time. A half-hot or switched outlet is a duplex outlet that has one half permanently “on” or ready to provide electricity while the other half can be turned off and an via an ordinary wall switch. While the entire duplex outlet could be turned on via a wall switch, only one of the two plug-ins is usually switched; this leaves the other half permanently powered for other uses.

Dimmers come in two basic wiring configurations: standard single-pole dimmers and three-way dimmers. With a standard single-pole dimmer, a single switch controls the light. With a three-way dimmer, you can control a light with two switches.

A three-way switch is used to control a fixture from two different locations. A three-way switch can be used to control the fan and light individually from each location, or combined with one switch at each location controlling both functions. Three-way switches are always used in pairs. The simple rule to make wiring easy is that the power leg connects to the common lug of one switch, and the switch leg connects to the common lug of the other switch.

Preparation and Wiring 1 Mount the approved ceiling fan box following manufacturer’s directions. Mount either the double gang or single gang boxes in the two separate control locations. Use the double gang box for individual control of fan and light functions and the single gang box for combined control of fan and light functions. Route the wire into the box through one of the box entry holes. Cut the wire leaving about a 6-inch tail outside the box.

Route all the wires into the boxes through one of the box entry holes. Cut all the wires leaving about a 6-inch tail outside the box. Tighten all the box wire clamps if so equipped. Install electrical cable staples to secure the electrical cables. One staple is required within 8 inches of the box.
