Please Note: To illustrate the wiring of these switches, Switch Boxes and Fixture Boxes are not shown but are obviously required for every application. These diagrams are shown as using the Romex wiring method. These Romex cables contain a ground conductor which is required for all applications as well. The ground conductors are always bonded together to insure the integrity of the ground path. If you are using metal boxes, the ground conductor must be attached to each box by using a threaded ground screw or provided attachment.

The frames of the switches which have a ground screw are to be attached to the ground conductor as required. Explanation of Wiring Diagram 1. Question: Your example shows 2 wire Romex but most Romex I have seen has three wires one white-one black and an un-shrouded copper ground wire.

What is the correct connection for this ground wire? Answer: As explained in this page above: These Type-NM cables contain a ground conductor which is required for all applications as well.

I have an existing light switch, and I want to add a second switch for a new light that will be operated separately. The power comes into the switch which operates a single light at the end of the circuit. Is there a simple way to do this or should I get an electrician?

The task of installing additional wiring for a light switch and new light fixture will depend on available access to the proposed location.

Hiring a qualified electrician will ensure that the installation is performed correctly where the existing circuit wires will be identified, and new circuit wiring will be extended to the new light switch and then out to the new light fixture.

Special attention will be given to the existing circuit capacity, the wire type and size, as well as making sure the additional wiring is protected and installed according to all the electrical codes that will apply.

Question from Denny, a Handyman in Sudbury Ontario Canada, Canada: How do I close off an existing light and add two new lights off of the existing light switch? I have a single light on a single switch in my kitchen ceiling. I want to close off the existing light and run two new lights off of the existing light box. It is not far from the existing light, so will I need to run wire from existing box to the two new boxes.

How do I close it off? The easiest way to add new light fixtures is to run the new wiring to the existing light fixture, splice the wires together as the old fixture was connected and then place a decorative blank cover over the fixture box.

Arlington makes a white blank fixture box cover that works very well for this type of application. If you would like to remove the light fixture box, and there is access to the attic area then the fixture box could be removed, and the wiring installed into a new junction box located in an accessible location where the new wiring for the additional light fixtures may be connected.Variety of pontoon boat wiring schematic.

A wiring diagram is a simplified conventional photographic representation of an electrical circuit. It reveals the parts of the circuit as simplified shapes, as well as the power and signal links between the devices.

A wiring diagram generally gives information about the relative position and also arrangement of devices and terminals on the gadgets, in order to help in structure or servicing the device. A photographic diagram would certainly show more detail of the physical look, whereas a wiring diagram uses a much more symbolic symbols to emphasize affiliations over physical appearance. A wiring diagram is often used to fix problems as well as making certain that the links have actually been made and also that everything is existing.

Collection of pontoon boat wiring schematic. Click on the image to enlarge, and then save it to your computer by right clicking on the image. A wiring diagram is a basic aesthetic representation of the physical links and physical design of an electrical system or circuit.

It reveals just how the electrical wires are adjoined as well as could likewise reveal where components and also parts might be attached to the system. Use electrical wiring layouts to help in structure or manufacturing the circuit or electronic device. They are also beneficial for making repair work.

Do It Yourself lovers use circuitry representations but they are likewise usual in house structure as well as automobile repair. A house contractor will certainly desire to validate the physical area of electric outlets and also light fixtures utilizing a wiring diagram to avoid expensive blunders and also developing code infractions.

A schematic reveals the plan and also function for an electric circuit, yet is not worried with the physical layout of the cords. Electrical wiring representations demonstrate how the cables are linked and where they ought to found in the real tool, as well as the physical links between all the parts.

Unlike a photographic diagram, a wiring diagram makes use of abstract or streamlined forms and also lines to reveal components. Pictorial layouts are usually pictures with tags or highly-detailed illustrations of the physical parts.

If a line touching one more line has a black dot, it suggests the lines are connected. Most signs used on a wiring diagram look like abstract variations of the real objects they stand for. A switch will certainly be a break in the line with a line at an angle to the cord, a lot like a light switch you could flip on as well as off.This is the circuit diagram of staircase light with automatic switch off.

It based on timer which is can be adjusted with the needs of the time of walking climbing up and going down on the staircase. We have been all acquainted with all the electrical wiring design that joins an electrical bulb with two switches: one at the bottom of a staircase and also the other at the top.

Wiring is completed such that both of the two switches can be utilized to switch the light on or off. In this kind of a wiring design, whilst climbing up the staircase that is in dark, the switch positioned at the bottom of the staircase is applied to switch on the light.

The circuit shown right here is definitely an electronic-cum-electrical design to obtain a comparable facility as given from the hard-wired electrical method, but you have to use the switch only one time. With every push and release of both of the two switches, light bulb L1 lights up for a preset time period of, say, 40 seconds, that is thought to be enough for climbing up or heading down the staircase.

The light bulb goes off automatically after the set 40 seconds. Switches S1 and S2 are definitely the two micro-switches, which give low inputs towards the respective de-bouncing circuits. Every de-bouncing circuit is constructed close to two NAND gates linked back to back. The de-bouncing circuits make sure a clean, bounce-free pulse at the output each time the micro-switch is pushed and released. So each time you push and release both of the micro-switches, you will get a positive-going pulse at the junction of the cathodes of diodes D1 and D2.

Automatic Switch-Off Staircase Light

These pulses are utilized to trigger the monostable circuit designed close to timer IC2. On the trailing edge of the pulse, the output of the monostable goes high for any time period of 40 seconds. This drives relay-driver transistor 2N T1 wired as being a switch. Light bulb L1 switches off once the relay gets de-energised right after second pulse period. Free-wheeling diode D4 1N protects transistor T1 against transients during relay switch-off function.

It is possible to also use regulated 9V power source. Build the circuit on a general-purpose PCB and keep inside a compact container. Connect micro-switches S1 and S2 close to top and bottom of the staircase by way of versatile wires and light bulb in the middle of the staircase. Prev Automatic Switching-on Emergency Light.Wiring light switch is first step which learn by a electrician or electrical student.

This connection is very simple connection and most used in electrical house wiring. This connection can be done by one way switch, a light bulb socket, light bulb and electric wires. From this post you complete learn about light switch wiring with a simple diagram and video tutorial in English language.

And this will be complete guide of wiring a light switch. The wiring of light switch is very simple connection but before we start the wiring connection. First I want to highlight those things which we use for doing this connection. We use a one way switch single way switch which is normally open contacts internally.

Rocker Switch Wiring Diagrams

And when you move or push switch, the switch make internally close contacts. One thing more to wire a light switch the first thing which we need the electric supply. We can get supply from the main distribution board or other place where we have the power source connection point. But before you are going to start work and getting the power supply. We need to switch off the main circuit breaker. And then start work because in electrical work the most important thing is safety and protection.

So safety first. First switch off the main circuit breaker to want to start work, if your wiring in conduit then use steel wire to move pass the electric cables foam conduit pipes. One thing more to wire a light switch with AC current Alternating current we will start our work with three color electric wires which are red, black and Green.

Mostly we use these color code for single phase wiring installation where red is used for phase hot wire black for neutral and green for earth or ground. If you are using the metal junction box then connect the earthling wire, however in some place the one way switch body are made for metal so we need earth wire for switch body. As I told in above words that in electrical works the most important thing safety and protection and earthling system is a good protection system.

So always install the earthling system in every electrical installation. Come to wiring connection. Wiring of a light switch is very simple and easy connection. You need to connect your neutral wire to light socket and hot wire to the switch and from the switch you connect the wire to light bulb socket other free terminal and ground wire to the one way switch earthling point as I shown in the below diagram.By code, the number of conductors allowed in a box are limited depending on box size and wire gauge.

3 Way Switch Wiring Diagrams

Calculate total conductors allowed in a box before adding new wiring, etc. Check local regulations for restrictions and permit requirements before beginning electrical work. The user of this information is responsible for following all applicable regulations and best practices when performing electrical work. If the user is unable to perform electrical work themselves, a qualified electrician should be consulted.

How to Read These Diagrams. This page contains wiring diagrams for household light switches and includes: a switch loop, single-pole switches, light dimmer, and a few choices for wiring a outlet switch combo device. Also included are wiring arrangements for multiple light fixtures controlled by one switch, two switches on one box, and a split receptacle controlled by two switches. When the electrical source originates at a light fixture and is controlled from a remote location, a switch loop is used.

This circuit is wired with a 2-wire cable running from the light to the switch location. The neutral from the source is connected directly to the neutral terminal on the light and the source hot is spliced with the white loop wire. The white wire is marked black on both ends to identify it as hot. At SW1 it is connected to one of the terminals. The black loop wire is connected to the other terminal and at the light, to the hot terminal on the fixture.

This is an updated version of the first arrangement. Because the electrical code as of the NEC update requires a neutral wire in most new switch boxes, a 3-wire cable runs between the light and switch. The red and black are used for hot and the white neutral wire at the switch box allows for powering a timer, remote control, or other programmable switch. Here a single-pole switch controls the power to a light fixture. The source is at the switch and 2-wire cable runs from there to the light.

The source hot wire is connected to a switch terminal and the other terminal is connected to the black cable wire. The neutral wire from the source is spliced to the white cable wire and continues on to the light. At the light, the white wire connects to the neutral terminal and the black wire connects to the hot. Here two switches are wired in the same box to control two separate lights.

The source is at the switch box and a 2-wire cable is run to each light. One source is spliced to each switch with a pigtail to power the two lights. This diagram illustrates wiring for one switch to control 2 or more lights. The source is at SW1 and 2-wire cable runs from there to the fixtures. The hot and neutral terminals on each fixture are spliced with a pigtail to the circuit wires which then continue on to the next light.

This is the simplest arrangement for more than one light on a single switch. A rheostat, or dimmer, makes it possible to vary the current flowing to a light fixture thereby varying the intensity of the light.

The dimmer switch will have stranded wires that must be sliced to the solid cable wiring in a pigtail fashion. A device like this should only be used with an incandescent light fixture and not with a ceiling fan or other motor. See wiring a speed controller for wiring a rheostat to control fan speed. To wire this circuit, 2-wire cable runs from the dimmer to the light. The source is at the dimmer and the hot wire is spliced to one hot wire on the device. The other wire from the dimmer is spliced to the black cable wire which runs on to the hot terminal on the light.As a resource for our customers, we provide below a collection of explanations, wiring diagrams, how to videos, etc of some of the most common Carling rocker switches that we sell.

Additional switch specific information can also be found on the product pages for each part. It will have one incandecent lamp at the top of the switch that illuminates automatically when the switch is on.

This switch will replace a V1DA rocker switch as well, which has plastic barriers between the terminals on the back. Please also see our: Etched Marine labeled backlit rocket switches. Or read more about how backlit switches work.

The additional terminal is at terminal 8 and controls the top light in the switch called an independent light. All actuators sold on this site will fit this switch. The wiring diagram to the right shows how the contacts and lamps are wired internally. The VJD1 rocker switch has 7 prongs on the back, called terminals. For marine applications an extremely common use for this VJD1 switch is as a Navigation and Anchor light switch. This wiring diagram applies to several switches with the only difference being the color of the lights.

It has two independent lights… one at the top, and one at the bottom. Notice on the wiring diagram that of the 10 prongs spade connectors, called termianls on the back, four 4 make the rocker switch lights function, while the remaining six are used for the electromechanical switching contacts. This switch body does have two isolated negative inputs T9 and T7 for each lamp or LED in the switch. This switch body is meant to be paired with a rocker switch actuator.

All actuators sold on this site will fit this switch, but with independent lights this etched switch cover will work best. This wiring diagram applies to several switch body variations that apply to lighting color only, otherwise the switches are the same. Or these terminals can be ignored for non-backlit switch banks.

This rocker switch is often used to reverse polarity on an electric motor. The center ON position is remains on while the momentary ON function at the top is being pressed.

The section below has wiring diagrams the are specific to marine rocker switch panels. Finally we have a Wiring Diagram for how to back light illuminated carling rocker switches in a rocker switch panel. We also have marine specific rocker switch wiring diagrams toward the bottom of this page. This switch will light the bottom light when it is down, and the upper light when it is up. Independent lights are triggered by en external source… like another switch.

First of all we need to go over a little terminology so you know exactly what is being discussed. It should also help in understanding the functions of each type of switch.

The cable consist of a black wire, a white wire and a bare copper wire. When wiring a 2-way switch circuit, all we want to do is to control the black wire hot wire to turn on and off the load. Now in the diagram above, The power source is coming in from the left. Notice the black wire is the only wire that we are controlling through the 2-way switch.

House Wiring Diagrams and Project Guides

You have an incoming hot wire black going to one screw it does not matter if you use the brass or silver screw on the side of the 2-way switch and a black wire from the other screw on the 2-way switch going to the load light, ceiling fan etc. The white wires are wire nutted together so they can continue the circuit.

Now as for the ground wire. It is very important to connect the ground wire to the switch as well. The Green screw on the 2-way switch is for the ground so all ground wires should be connected as seen below.

All ground wires bare copper are all now connected incoming ground, load ground and switch ground. This makes for a safe protected circuit by having all grounds intact. So what have we accomplished. By wiring a 2-way switch, The circuit below shows the basic concept of electricity flow to the load. Let's assume the load you are controlling is a light. The electricity flows from the hot wire black through the 2-way switch shown in off position and then to the light and returns through the neutral wire white.

This is a completed circuit. Now by understanding the diagram above, go up to the top diagram and by using the concept shown here, just use your mouse pointer on that diagram and follow the flow from black wire hot wire to the load and return through the white wire neutral. This should give you a good basic understanding how the 2-way switch circuit works and will help you in adding or changing a 2-way switch. So now that you have a basic concept of wiring a 2-way switch, let's look at the following 2-way switch diagrams to see which type of circuit scenario you have.

After you have pulled your switch out from the wall, the wires in the box and connecting to the switch should look like one of the following.
