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.

3 way switch wiring diagram with the power in cable entering the light box. Wiring Diagram #1, Power In the Light Box. In this example, the power in cable enters the light box. This method of running the wire is common when several light fixtures share one common breaker, and the switches are both on the same wall. Cables need to be run into ...
2 way switch (3 wire system, old cable colours) 2 way switch (two wire control) Three way switching. ... Fig 1: Two way switching schematic wiring diagram (3 wire control) The schematic is nice and simple to visualise the principal of how a two way switch works but is little help when it coms to actually wiring this up in real life!!
Wiring Diagram 3 Way Switch with Light at the End. In this diagram, the electrical source is at the first switch and the light is located at the end of the circuit. Three wire cable runs between the switches and 2 wire cable runs to the light. The black and red wires between SW1 and SW2 are connected to the traveler terminals.

When wiring a 2 way switch circuit, all you're really doing is controlling the power flow (Switching off on) to the load (a light, lamp, outlet, ceiling fan etc..) Now a typical circuit will contain a 3 wire cable known as romex.
Yes, you can use 3 way (UK: 2 way) as 2 way (UK: 1 way) switches. It will work fine. Simply make sure the screws are different colors; you want the common terminal and one of the messengers; not both messengers.. You can do the same with a 4 way (UK: the kind that goes between two 2 ways), again choose screws of different colors, i.e. one from the upstream "side" and one from the downstream ...
