3 Way light switch wiring diagram

Three - wire cable runs between the switches and 2- wire cable runs to the light. 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. The ground wire is pigtailed with a wire connector at the switch boxes and the ceiling box. Wiring a three way light switch. 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.

What is common in the diagrams above and with any - way switch circuit is that the power hot wire coming into the circuit will always go to the common terminal of the first switch. The hot wire from light always goes to the common terminal of the second switch. Unfortunately, not all - way switches are wired the conventional way. If you have any problems with these switches , it may be best to call an electrician. Three - way switch wiring requires the use of a three -conductor cable to connect the two switches.

The red wire in the cable is known as the traveler, and it connects to the black terminal screws on the pair of switches. A - way switch has three screws plus the green grounding screw. The most important screw is the black one. Now discussing 3-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.

Right now, each switch is functioning like a single pole, turning. However, it can be done with a little patience and attention to detail. In this circuit, two light fixtures are shown but more can be added by duplicating the wiring arrangement between the fixtures for each additional light. Here the source is at the first switch , SW and - wire cable runs from there to the first light , L1.

Pre wire Dimmer Switches Most - Way dimmers come with pre-wired leads that are color coded and explained below. A three - way switch has four different screw terminals on its body: The green screw attached to the metal strap of the switch is always for the ground wire (this is the bare copper or green insulated wire ). However on each - way switch , you have a black screw, this is the special one. On the power coming in from the panel, you would connect that black wire to the one black screw. These diagrams illustrate how to wire a pair of three - way light switches in three different situations. Three - way light switches , used where you want to control a light from two locations, such as from both ends of a staircase or hallway, are built and wired a little differently than a conventional single-pole light switch.

There are many ways to wire them, as to where the power goes, etc. It is easy to wire these wrong. First of all, the white ground wire does not go to either of the two - way switches when you are trying to make switches operate light. The wiring method will depend on whether your power goes to the switch first or the light first.

It should also help in understanding the functions of each type of switch. The cable consist of a black wire , a. Fold Line DOCUMENTATION LEVITON INSTRUCTION. You will improvement from using residential wiring diagrams if you scheme on completing electrical wiring projects in your home.

This cable consists of three cores - brown, grey and black, which are all Line colours, and an Earth wire. Connect the Line (brown) wire coming from the light together with the CoreEarth cable black wire , in to the Lterminal of the two- way switch. Image: light switch image by David Ng from Fotolia.

Leviton is one of the top producers of wiring devices. The company makes a quality three - way switch that is reliable. Typically used for hallways and staircases, three - way switches are used in instances where two separate switches control one.

The difference between a single-pole. Use these step-by-step instructions to install a three - way switch and wire a circuit. One way circuit controls a light.

Controlling a light with three or more switches. For more than two switches , one or more 4- way switches are added between the - way switches. A 4- way switch has two positions. In the first position, the contacts are connected straight through, so that the switch has no effect.

Wrap the switch terminals with tape and push the switch carefully into the box. Install the last - way switch. The connections here are the same except that the black wire carrying power to the lighting outlet(s) is connected to the dark colored screw.

This is very similar to the two way switching circuit but with and additional intermediate switch introduced into the three wire control cable that links the two end light switches. Assortment of wiring diagram way switch ceiling fan and light. A wiring diagram is a streamlined conventional photographic depiction of an electrical circuit. It shows the elements of the circuit as streamlined forms, and also the power and also signal connections in between the devices.

The common screw may be located in a different spot on your - way switch than the location indicated in the drawings above, but make sure that the wire indicated in the drawings to be connected to the.
