3 Way wire

Wiring a three way light switch. With a pair of 3-way switches, either switch can make or break the connection that completes the circuit to the light. The cable should also have a ground wire , or a total of four wire s in the cable. The system also requires three-way switches.

Pick the diagram that is most like the scenario you are in and see if you can wire your switch! A 3- wire NM connects the traveler terminals of the first and second 3- way switch together. Traveler wire s are interchangeable on each switch. The common terminal of the second 3- way switch connects to the light fixture(s). Three- way switch wiring requires the use of a three-conductor cable to connect the two switches.

A - way switch allows you to turn a light on or off from two different switches. In this diagram the source for the circuit is at the light fixture and the two switches come after. Two- wire cable runs from the light, to SW and 3-wire cable runs between SWand SW2.

Now discussing - way light switch wiring diagram as also discussed above the color codes of the wires as having three insulated conductors as black as hot, red as switch wire or called traveler and white as common wire as also shown when light is connected to both black and white wires. However on each - way switch, you have a black screw, this is the special one. The red wire in the cable is known as the traveler, and it connects to the black terminal screws on the pair of switches. On the power coming in from the panel, you would connect that black wire to the one black screw. The key to wiring two three-way switches is to run the two wires that were originally connected to the old switch (Photo 1) to the “common” terminals.

The “travelers” can go to either terminal. The switch may also have several ways to make the wire connections. All switches have screws on the side, but some also come with push-fitting holes or slots to slide the wire into. Bundle the three same-colored wires together and uses wire -cutters to trim the ends to an even length.

Using wire strippers, strip off a section of insulation from each wire. To splice, hold the three wires together in one han while twisting them together with pliers (Image 1). The hot wire leading from the - way switch circuit will have no power, since all power must travel through the switches.

If one of the black (hot) wires does have power, then that is the wire for the always on plug. Two three- way switches control one light with the electric power coming through the first switch, flowing to the second switch, and then to the light fixture. The ground wire goes through both switch boxes and the ceiling light box and it is connected at all junctions, except the light, with a pigtail (short piece of wire ) and wire connector. The strap and body are integrated with ultra sonic welding for extra durability.

A way has five connections: one groun and circuit terminals divided into two matching pairs. Waytek carries crimping tools for making solid connections. Light is controlled by two three - way switches with the light between the switches and the power first going through a switch, then to the light, and onto the second three - way switch. For each position on the lever, a lug on each stage is connected to its respective common. To get started with the Telecaster three- way switch wiring, look at the two rows of tabs at the bottom of the switch.

When replacing a three-way light switch, be sure to return the wires to the proper screw terminals. On three-way switches, two terminals are the same color and the third terminal—called the common terminal—is a different metal or color. Put a piece of tape on the wire that goes to the common terminal screw.

One wire might be bare copper or have green insulation on it. This one is the ground wire and connects to the green screw on the - way switch. The remaining two wires are called travelers and simply extend to the other - way switch. Compare Dimmer To Old Switch. Look at your new dimmer switch or a new - way switch.

All of the switches shown below are - way. With conventional wiring , the common wire from one switch connects to line, the common wire from the other switch connects to the load (lights). Once you have your diagram made showing the wiring locations of the different colored wires, and the different color screw heads, you are ready to make the change.

Disconnect the three wires from the three- way switch. Connect the wire from the common lug to the switch leg of the two- way switch, and connect the traveler leg that was hot from the test above to the power leg of the two- way switch. This wire diagram shows the wiring for source power into the first three way switch, then - wire cable to the next way light switch, and then on to the light or light fixtures. The - way circuit is a very common system found within most residential installations.

A 4- way switch is always placed in between two - way switches. Watch the 4- Way Switch video below and pay attention. You can have an indefinite number of 4- way switches in a circuit. They all must be between the two - way switches. The most common wiring requirements of any hardwired automated 3-way light switch is a neutral wire and a traveler.

Yes, there are a few…(read very, very, very few) switches that don’t require a neutral, but those will limit you to incandescent only. How to Wire a 3-Way Switch. Take all safety precautions when working with electricity. The way switch allows a person to turn off and on a light from two different locations.

Pull these wires out of the box and separate them so there is no bare copper touching any other metal. Turn the panel breaker back on. More variations of - way (two switch) circuits.
