Be careful when re-using older switches as some don't have a ground terminal; current NEC code requires that every switch be grounded. Wire installed next to another wire will pick up some voltage, though. If you want the switches to control the new lights, they should be tied to the same wires that the old light was. By toggling any switch, the light will now turn on. Another 14/3 wire is used to connect another three way switch and finally a 14/2 wire is used to connect to the light or multiple light fixtures. Dan Harmon (author) from Boise, Idaho on May 23, 2011: I had never thought of that but yes, understanding the logic of a 4 way switch system would be a great way to begin learning about control and logic circuits. If you are doing anything more than simply replacing a defective 4-way switch please examine the link on how to wire a 3-way switch before proceeding; it will open in a new window that will return the reader here when it is closed. Terminate the ground wire and again splice the neutral wires without terminating them anywhere. June 23, 2017 at 9:12 pm . Remember one of the lights fed with two three way switches has zero voltage @ the light. Can y'all help me with a 4 way switch issue? Question: We have a bedroom overhead LED light that went out the other night. Each part ought to be placed and linked to different parts in specific manner. While other methods of physically getting the necessary wires to each switch are possible (see the article on wiring three-way switches), the 2011 National Electric Code, article 404.2.C, was changed to require a "neutral" (white) wire at each switch location whether it is actually used or not. Many require a neutral wire, so make sure that is available before purchasing. Make absolutely sure the power is turned off before proceeding. Dan Harmon (author) from Boise, Idaho on June 21, 2017: Look for loose connections, breakers turned off and bulbs burned out. Do you need a 3 way switch wiring diagram? Current code requires a neutral in each switch box, and you won't have one in the third box, which is why it will not meet code in most locations. Now it dead ends (not connected) which means the light is turned off. If more than three switches are needed, simply place more 4-way switches between the three way switches. The last light in the circuit has zero voltage @ the light when it is switched off. Your’s are way better. Dan has been a licensed journey-level electrician for some 17 years. Make sure that the circuit is dead before continuing or touching any bare wire. Conventional 4-Way Switch Wiring. 3-way circuits can vary depending on the method used at the time the home was wired. While it is quick and easy to simply push the wires into the new switch, and most electricians do that in the interest of saving time, it is preferable to put them under the screws as the springs in the holes will loosen over the years and make a poor connection. Likewise, any new wire used must match existing wire in size. Sleeve (ground). 4 Way Switch Wiring with Four Switches. 14 gauge wire is easier to handle and cheaper as well, but if you are tying into a 20 amp circuit you must use 12 gauge wire. The other end of that white switch leg, in the center box, needs to be colored (magic marker, black tape, some way to indicate it is NOT a neutral) and splices to the black going to the light. Make sure that the green or bare ground wire is always pigtailed out and terminated on all switches. In some countries the four-way is called an intermediate switch. The two wiring diagrams above are of a 3-way switch setup and the same basic setup with a 4 way light switch added. Turn the light on and turn breakers off or remove fuses one at a time until the light goes off. There are 4 places to terminate wire, plus a green screw at the top of the switch for the green or bare ground wire. One has three switches, two three way & one four way. Each of the diagrams in the 3-way switch article can be treated the same way; merely add the 4-way switch between the other two and terminate the traveler wires on the 4-way switch while making sure that there is a neutral in each box. Re-check all your connections and make sure something hasn't come out of a wire nut. Also, this example is just adding a single 4-way switch which will give you 3 locations to control your light. The two 4-ways are located between the two 3-ways and the traveler wires run from SW1 to T1 on the first 4-way. 4-way switches are only used when there are 3 or more light switches controlling one light fixture. Now don't let this be confused with where the switches are physically located in your home. OPTION #1: Power from light fixture to light switch Using needle nose pliers or other tool, bend the bare end of the wire into a small circle, loosen the screws as far as they will go, and work the wire under the screw head and around the screw in a clockwise manner (if put on backwards tightening the screw will tend to "unbend" the wire and it may come away from the screw). And finally, re-check again that everything is wired correctly - it is really easy to mis-wire somewhere in a set of 3 and 4 way switches. Keep in mind how the 4-way switch works. Use a circuit tester to find the bad wire. This allows you to control a load from other locations in addition to the (2) locations that a 3-way circuit provides. Fasten the switch with the two screws provided, refit the cover plate using the same screws that you carefully saved, and you're done. All that is required is wiring a 4-way switch between the (2) 3-way switches. Before going any further with the 4-way switch instructions, I would recommend you go to my Wiring a 3-way switch page and first become familiar with that circuit and how it functions. Each such lighting circuit will contain two 3-way switches and one or more 4-way switches (the number of 4-way switches that may be used in such a switching configuration is unlimited). In nearly every case these wires will enter the wall box in 2 separate cables. 3-Way/Multi-Switch Installation (4-Wire Switches & Dimmers) November 25, 2019 18:29; Updated; Installing C by GE smart switches on a 3-Way or Multi-Way circuit requires ALL switches on the same circuit to be a C by GE smart switch. AsktheBuilder.com: A 3 Way Switch and a 4 Way Switch can sometimes refuse to work. Tug firmly on each wire while holding the nut in the other hand; if it's going to come apart much better that it does so now rather than later, back in the box where you can't see it. The last wire will be either green or, more commonly, completely bare of insulation. If not, the structure won’t function as it should be. 4 Way Switch Wiring Diagram with Dimmer– wiring diagram is a simplified tolerable pictorial representation of an electrical circuit. That page and its links also discuss proper wire colors and several wiring … a couple examples would be: At each end of a hallway and a switch halfway down the hallwayor at the top & bottom of a stairway and a switch by the front door. Question: I have a switch that has 2, 3-way switches and 1, 4-way. Two of the lights have are switched with two three way switches. How to Wire a 4 Way Switch. I want to install an in-wall timer, what should I do? This switch has screws at the sides as well as the holes in the back. Dan Harmon (author) from Boise, Idaho on August 03, 2017: The only time I've had LED lights glow without the switch turned on was when used with an electronic dimmer. Now this one gets a little tricky by keeping track of what switch you toggle in your mind, just hang in there.Now the power source (black) is coming in from the left. The 4-way is used A 4 way switch wiring diagram is the clearest and easiest way to wire that pesky 4 way switch. Always make sure grounds are spliced together with a pigtail to the switch. Here are some wiring cases: The electricity source is connected to the 3-way switch first. The switch can be used to control the electricity supplying lights from three locations. A 20 amp switch can be used on a 15 amp circuit, but never put a 15 amp switch on a 20 amp circuit. How to wire a 4 way switch. We have tried to install a new light switch receptacle and still nothing works. There are four wires that are terminated (fastened to) a 4-way switch, plus the green or bare ground wire. At the center box, with a four-way switch, black and red from the first box goes to two terminals with the black and red going to the third box to the other two terminals.
