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.Log in or Sign up. Boat Design Net.
I'm new to wiring- have a few beginner books ordered, don't worry- and I recently purchased an attwood 3-pin pole light base so that I can install a bow light on my 16' fishing boat. So far I've tried to attach a fused positive lead from my pos control panel to the slot labeled 'power' on my toggle switch-- I've attached the grey wire of the pole base to the slot labeled 'accessory' on my toggle switch-- and I've attached the black negative wire from the pole base to the negative bus bar in my console Also attached an additional grounded wire from bus bar to toggle switch location labeled 'ground'.
After doing this, I can get the neon light on the switch to light up after flipping the switch, but cannot get a light in the pole base to illuminate no matter if I attach the grey wire OR the blue wire of the plug to the positive feed.
What am I doing wrong- do I need to utilize all 3 wires on this pole base in order for it to work?. What does the fixture look like you are plugging into the socket? BgladNov 22, I would say if they supplied three wires then it's there for a reason and has to be hooked up.
Did they provide a diagram or instructions? IkeNov 22, Test the wiring to the pole base with a multimeter. Or test it with a spare interior light or any 12v device or bilge pump or whatever to see if the right wire lights it up as expected with the switch at each position. It's about as simple a circuit as it gets.
Follow the diagram. If this is too much, call a buddy that's got some experience with 12 VDC electrics. It's not hard, but can be intimidating to some.
The Attwood site has installation instructions for your round pole socket base. From memory, the blue wire is connected to the courtesy light switch.
The gray wire is the nav light switch wire. The black is ground. You only need the two pin socket for a standard bi-color, round pole bow light. PARNov 22, Ok, ya, I mentioned the instructions. I don't have courtesy lights, or a courtesy light switch.
I simply have a console with a fused positive bus bar, an additional fused bus bar beside it, and 2 negative bus bars. You must log in or sign up to reply here. Show Ignored Content.How to wire a 2 way switch.
Wiring a 2-way switch is about as simple as it gets when it comes to basic house wiring. 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.
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.
Basic Light Pole Base Wiring Question
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. How To Wire It.Diagram Base Website Full Edition. In a section from the bookBrain by Philip Novella we are introduced into an example of a rather interesting, as well as puzzling case.
The situation that this article will deal with was that of a person who had a serious head injury. The explanation offered in the publication was that the damaged area of the brain was the temporal lobe.
This prior case shows us is that in order to spell out any circumstance, we have to look at it in the different angles introduced.
This is achieved by studying every part of the brain and seeing exactly what that part does and how it might be linked to everything else. In the case of this letter'L' in the structure of the brain, we see the termlight from the left side. Light happens in both the frontal and parietal lobes. A person is usually able to identify a mild by the one who said it or seeing it on a certain source.
If we were to ask somebody for their friends and family members, they would likely use their eyes for this purpose. In the case of this letter'A', we see the termanger at the right side of this diagram. Anger and aggression are made by the frontal lobes.
If someone sees or says an angry individual, it is usually simpler for somebody to recognize the individual as having anger compared to remember where they watched them or what they said. It isn't so easy to bear in mind that a light was seen or that the patient was angry. In the instance of the letter'B', we see the phrasebored in the center of the diagram. Everyone understands when somebody has enough of something. Many find themselves bored or irritated easily.
From the letter'D'we see the worddislike on the ideal side of this diagram. Dislike comes in the temporal lobes. One does not dislike someone without being conscious of it. A similar thing occurs with dislike. An individual can use anger for many distinct purposes. Sometimes anger is used to express jealousy or aggression. In summary, the letter'L' from the structure of the mind is pointing into the temporal lobe.
The letter'A' at the structure of the mind is pointing into the frontal lobe. The letter'B' from the diagram of the mind is pointing to the parietal lobe. User Blog. User Blog Global.

Several diagrams are included here that can be used to map 4 way and 3 way lighting circuits depending on the location of the source in relation to the switches and lights.
Included are a 4-way dimmer switch diagram and an arrangement that can be used to control room lights from four different locations. Check here for 4 way switch troubleshooting and help with 3 ways switches here. For circuits that control lights from two locations only, check the wiring diagrams at this link. In this basic 4 way light circuit, 3-wire cable runs between all the switches and 2-wire cable runs from the last switch to the light. The electrical source is at the first 3 way switch and the hot wire connects to the common there.
The circuit neutral is spliced at each switch box through to the light fixture using the white wire.
56 Ford F100 Wiring
The black and red wires running between the boxes are connected to the travelers on each switch. The common terminal on the 3 way switch at the end of the circuit connects to the black wire running to the hot terminal on the light.
Take note that the traveler wires from SW1 are connected to the T1 pair on the 4 way switch and the travelers going to SW2 are connected to the T2 pair. Each pair of traveler terminals on the 4 way must be connected to only one 3 way switch. Don't mix up the pairs or the circuit will not work properly. This diagram illustrates wiring for a 4 way circuit with the electrical source at the light fixture and the switches coming after.
Two-wire cable is run from the light to SW1 and 3-wire cable runs between the three switches. The source neutral wire is connected directly to the light fixture and the hot is spliced to the white cable wire running to SW1.
At SW1 it's spliced to the white wire running to the 4 way switch box where it's spliced to the white wire running to common terminal on SW2. The white wire is marked with black at each splice to identify it as hot. At SW1, the common terminal is connected to the black wire running to the light fixture hot terminal. The black and red wires running between the switches are used to connect the travelers on each switch. Here the circuit source is at the first 3 way switch and the light fixture is between there and the other switches.
Three-wire cable runs between the light and all the switches. The source hot wire is connected to the common on SW1 and the neutral wire is spliced through directly to the light fixture neutral terminal.
The black and red wires from SW1 are used as travelers and at the light fixture they are spliced to the red and white wires running to the 4 way switch.Two Simple Circuits: Series and Parallel
The black wire running to the 4-way switch is connected to the hot terminal on the light and at the switch box it's spliced to the black wire from the common on SW2. The red and white are used as travelers between the 4 way and SW2. The white wire is marked black at each end to mark it as hot. This wiring shows the light fixture and the electrical source together in the same box located between the switches.This page contains wiring diagrams for four different types of household lamps.
Included is a diagram for a two-circuit lamp switch to control a standard lamp socket at the top of the lamp and a smaller socket at the base for a low wattage bulb. Also included are diagrams for a standard lamp switch, a three way lamp switch, and a vintage floor lamp with 4 light bulbs. Lamp cords are usually all one color making the standard black-hot, white-neutral guidelines useless for determining polarity. Other methods are therefore used to determine the polarity on a lamp cord.
First, check the insulation on the cord wires closely and you will find either a textured bead or a thin colored line running along one wire, this is the neutral wire. The plain wire is the hot. If the cord isn't marked with a bead, then the strands of wire may be different colors to distinguish between them. In these cases, the silver-colored wire is usually the neutral and the brass-colored wire is the hot.
Another clue to polarity is the plug on the lamp cord, the wide prong being the neutral and the narrow one the hot. Most older lamp cords will have prongs that are the same size.
This is because polarity was not observed on electric lamps until the development of grounded circuits. With these lamps, the plug can be plugged into the receptacle outlet in either direction making polarity a non-issue. This diagram illustrates the wiring for a bedside lamp with two sockets. The top socket Aholds a standard incandescent bulb. The second socket Btypically holds a small, low-wattage bulb similar to a night light bulb. The switch allows for energizing the top bulb only, the night light only, both bulbs at once, or for turning both bulbs off.
This type of switch will be referred to as a 2 circuit lamp switch when shopping at home stores. Don't mistake this for a three way switch pictured belowthe two do not function in the same way. Here a 2-way push-button switch is wired to a lamp with 2 bulbs. This diagram can be used to rewire an old push-button lamp with a new switch replacement.
The hot wire from the cord is connected directly to the black wire on the switch and the neutral is spliced to the neutral contact on each bulb sockets.
The red and blue wires from the switch are each connected to the hot contact on one of the bulb sockets. This is a wiring diagram for a standard 3-way lamp switch. The socket is used with a three way bulb containing 2 separate elements that are energized separately and then together as the switch knob is turned for varying degrees of light. These sockets have two terminals, one for the hot wire and one for the neutral.
A third contact may be present but is not used for this circuit. This diagram illustrates wiring for a standard, one setting lamp. This socket has two terminals: the brass for hot and the silver for the neutral wire. The lamp cord is connected directly to these terminals observing the polarity described at the top of this page.
This is a wiring diagram for a vintage floor lamp with 4 bulbs, one main bulb and 3 peripheral, and usually smaller, bulbs. The main bulb threads into a standard socket with an integrated switch and the three peripheral bulbs are wired to a single switch usually located near the central socket.
The secondary switch may have wires colored black, blue, and red or if it's an old switch, other colors or texturing may be used to distinguish them.Whenever I feel a need to hire an electrician, I simply click on the link Electriciansjohannesburg.
