I know of 4 possible ways to wire 3-way switches, depending on the sequence of your source wire and your switches. Let me set the scene: The source cable can enter any one of these three first, either switch 1, the light box, or switch 2. Here are the four options as far as how the cable can run: I am unable to send the answer as to how to wire all four options, because it makes my answer too long for “Yahoo Answers”.

How to Wire Three-Way Light Switches
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.
The square relay pinout shows how the relay socket is configured for wiring. This pinout image is only a 2-pole diagram for room on the page purposes, but you can get the picture here with this one since a 3-pole will just have 1 more set of contacts.
Installing Outlets Most switches and outlets are installed after mechanical rough-ins, drywall and paint are completed. When you shop for devices like switches and outlets, there are several different types to wade through. Make sure to get the device that works properly with the circuit. The type of switch you install is determined by the circuit’s wiring scheme.
Outlets are pretty standard, but GFCIs are required in some rooms and box size is another thing to consider. Sizing Junction Boxes All switches and outlets receptacles need a properly-sized junction electrical box. Installing an undersized box is probably the most common wiring mistake for do-it-yourselfers. When in doubt, it’s usually best to use a larger box. If you’re not sure about box size requirements, remember to ask your electrical inspector when submitting diagrams.
Here’s one way to calculate minimum box size: Count the number of wires for the box. Take that number, add one for each cable clamp, and two for each device like a switch or outlet. If the box contains only gauge wires, multiply the total by 2 cubic inches. Or, for gauge wires, multiply the total by 2.
How to Wire a Light Switch
There are two common ways to wire a switched light. The first method shown in both of Eric’s diagrams is to bring both the “Hot” black wire and common or neutral white wire into the switch’s box. The white wire is passed on to the light fixture and the black one is connected to the “in” side of the switch. A black wire is then taken from the “out” side of the switch on up to the other terminal on the light fixture.
If your circuit were wired this way, it would be easy to add an outlet, using Eric’s diagrams. A wire, connected to the other side of the switch and is sent back up to the light’s box where it is connected to the other side of the light fixture.
Note where all wires hook up on the existing switch. The hot wire is either red or black. The grounding wire is yellow, green or bare, and the white wires are neutral.
How to Install a Double Pole Switch By Kathryn Rateliff Barr How to Install a Double Pole Switch Hunker SAVE In most states, the building owner can legally install electrical switches, although contracting the work through a certified electrician can provide a margin of added safety that the average do-it-yourself enthusiast cannot. A homeowner might install the switch to control a large electric furnace directly wired into household current.
The owner might locate the switch at the entrance of the room so he can turn on the unit when he switches on the lights. A double pole switch can allow you to turn on an appliance from across the room. Step 1 Identify the required circuit by opening the fuse box and locating the V fuses. A V fuse usually appears as two regular V fuses with the handles connected together.
It may also appear as a double-wide fuse with a single handle. There may be more than one V fuse, so be sure you locate the correct circuit. Turn off the fuses one at a time. Check the appliance you wish to control with the switch. When you turn off the right fuse, the appliance will no longer work.

Now grab both black and white conductors, and pull them apart in opposite directions so that the jacket rips, continuing until the tear reaches the inside of the box. Stripping the jacket with a knife is trickier.
Any nicks should be covered completely with two wrappings of electrical tape. Used instead of a standard switch, a dimmer gives you more flexibility in lighting control. Installation is often easier than a single-pole switch because many dimmers require wire nuts to connect to the power source rather than the screw terminals found on conventional switches. Strip and bend the hooks. Make an open-ended loop on the black wires with needle-nose pliers or wire strippers.
Next, make a loop in a 6-in.

Jun 20, , The light inside switch has to have a neutral. The fact that there is a red wire in this switch box at all leads me to believe that there is no neutral. It sounds like this is a three way switch box. The question is was the white wire hooked to the switch that you took out.
There are several types of light switches. Single Pole Switch. A one-pole switch controls one light fixture from a single location, such as a bedroom light with a single switch as you walk in the.
Most modern switches have screw terminals on each side and may also have holes in the back to accept the end of the wire. You can easily loosen the screws on the side of the device with a standard screwdriver turning counterclockwise , but you may find getting the wires out of the back of the device tricky. To remove these wires, insert the blade of a small screwdriver into the slot under the hole into which the wire is inserted and push in as you pull the wire loose. Pushing the blade of the screwdriver into the slot releases the grip on the inserted wire.
Here are descriptions of the wires and where they go: The white neutral wire connects to the silver screw, or you place it in the back wire hole on the same side of the device as the silver screw. The black hot wire goes to the brass screw or into the hole in the back of the device on the same side as the brass screw. This wire is sometimes red. The green or bare copper ground wire, if the device has one, attaches to the green screw terminal on the switch or to the electrical box.
To replace this kind of switch, follow these steps: Turn off the power to the switch at the main circuit breaker or fuse panel. Unscrew and remove the switch plate; then use a voltage tester to make sure that the circuit is dead. Unscrew the switch from the electrical box and pull it out with the wires still attached.

You need to really understand how current flows and is interrupted by a simple single-pole switch before you start to tackle a 4-way switch! Single Pole Switch Video This is what most of the switches in your home look like.
Dirty Steve , I want to be able to turn off and on with either switch. Anyone know how it’s done? Run power into one switch, run two traveler wires between the switches, and then power out of the second switch up to your lights. My lazy way of making a drawing in the link below! Say I walk in the front of the trailer and turn on the lights. Then walk out the back door and flip the back switch, the light is going to stay on unless I go back and open the front switch , right?
Sent from my SM-G V using Tapatalk yes, both switches have to be off in order to get the lights off. It’s super easy to wire them it’s just like from the top and bottom of a stairway , you just have to run two wires between the switches so either one works in either position. The Google link I posted has pics, video’s, website links, etc.
