The light and Switches wiring diagram is a graphical representation of the physical connections and physical layout of an electrical system or circuit. As shown in the below diagram, a light and switches wiring plan shows how the electrical wires are interconnected and can also show where fixtures and components are connected to the system. As per the light and switches wiring plan picture, a wiring diagram is a simplified conventional pictorial representation of an electrical circuit. A light and switch wiring plan usually gives information about the relative position and arrangement of devices and terminals to help build or service the device. It should be noted here that the light and switches wiring plan diagram is unlike a schematic diagram, where the arrangement of the components' interconnections on the diagram usually does not correspond to the physical locations in the finished device.
