A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices.
A wiring diagram usually gives information about the relative position and arrangement of devices and terminals on the devices, to help in building or servicing the device. This is unlike a schematic diagram, where the arrangement of the components' interconnections on the diagram usually does not correspond to the components' physical locations in the finished device. A pictorial diagram would show more detail of the physical appearance, whereas a wiring diagram uses a more symbolic notation to emphasize interconnections over physical appearance.
A wiring diagram is often used to troubleshoot problems and to make sure that all the connections have been made and that everything is present.
Architectural wiring diagrams show the approximate locations and interconnections of receptacles, lighting, and permanent electrical services in a building. Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be on a common circuit.
Wiring diagrams use standard symbols for wiring devices, usually different from those used on schematic diagrams. The electrical symbols not only show where something is to be installed, but also what type of device is being installed. For example, a surface ceiling light is shown by one symbol, a recessed ceiling light has a different symbol, and a surface fluorescent light has another symbol. Each type of switch has a different symbol and so do the various outlets. There are symbols that show the location of smoke detectors, the doorbell chime, and thermostat. On large projects symbols may be numbered to show, for example, the panel board and circuit to which the device connects, and also to identify which of several types of fixture are to be installed at that location.
A set of wiring diagrams may be required by the electrical inspection authority to approve connection of the residence to the public electrical supply system.
Wiring diagrams will also include panel schedules for circuit breaker panelboards, and riser diagrams for special services such as fire alarm or closed circuit television or other special services.

A 2 Way Switch Wiring Diagram with Power Feed from the Switch light : The power source comes from the fixture and then connects to the power terminal. You will see that there is a hot wire that is then spliced through a switch and that then goes to the hot terminal of the light.
2 way switching means having two or more switches in different locations to control one lamp.They are wired so that operation of either switch will control the light. This arrangement is often found in stairways, with one switch upstairs and one switch downstairs or in long hallways with a switch at either end.

A 4 way switch wiring diagram is the clearest and easiest way to wire that pesky 4 way switch. I have a few of the most common ways in wiring a 4 way switch to help you with your basic home wiring projects. Do you need a 3 way switch wiring diagram? OPTION #1: Power from light fixture to light switch
4 Way Dimmer Switch Wiring Diagram. This is the wiring for a dimmer in a 4 way circuit. Three wire cable runs between all the switches and 2 wire cable runs to the light. To make this circuit work, a 3 way dimmer can be used in place of one, or both of the standard 3 way switches. In fact, a dimmer can be used this way in place of any of the 3 ...
Two Way Switch Wiring. The COM, L 1, and L 2 are the three terminals of the two way switch. The L1 terminals of both the switches are connected to phase, and L2 terminals of both the switches connected to one end of the bulb terminal and the other end of the bulb terminal are connected to neutral of the AC supply.
The primary difference between the two kits is the microcontroller included in the kit. The SparkFun Inventor's Kit includes a SparkFun RedBoard, while the SparkFun Inventor's Kit for Arduino Uno includes an Arduino Uno R3.At the heart of each is the ATmega328p microcontroller, giving both the same functionality underneath the hood.
Congratulations! on wiring a 3 way circuit. In my mind wiring is one thing, but to look at a diagram as the one above and understand the principle involved, that is the key to do it yourself house wiring. If you're simply replacing a 3 way switch, the diagrams below will show the different scenarios on how your circuit could possibly be wired.
Regardless of what 3 way switch wiring diagram, you're following, you'll need to use a 3 wire cable to connect the two 3 way light switches. So what you should see if you have the correct 3 wire electrical cable (Romex) is a black (power) white (neutral) and now a 3rd (Red) wire.
Diagram #1 above, shows the electricity source starting at the left 3 way switch. Wiring Diagrams for 3 Way Switches. 3 way switch diagram #2 above, shows the electricity source starting at the fixture. The white wire of the cable going to the switch is attached to the black line in the fixture box using a wire nut.
