Basic Electrical Wiring Diagram Symbols. Here is a standard wiring symbol legend showing a detailed documentation of common symbols that are used in wiring diagrams home wiring plans and electrical wiring blueprints. Wiring diagrams use simplified symbols to represent switches lights outlets etc.
For example a few basic symbols common to electrical schematics are shown as 1 switch 2 battery 3 resistor 4 ground. Elementary diagram connections wire numbering. 1 master element 2 time delay starting or closing relay 3 checking or interlocking relay 4 master contactor 5 stopping device 6 starting circuit breaker 7 rate of change relay 8 control power disconnecting device 9 reversing device 10 unit sequence switch 11 multifunction device 12 overspeed device 13 synchronous speed device 14 underspeed device 15 speed.

Then think about the layout of these symbols. Automotive electrical diagrams provide symbols that represent circuit component functions. For example a few basic symbols common to electrical schematics are shown as 1 switch 2 battery 3 resistor 4 ground. Note the switch symbol displays an open or closed circuit path which is what an actual switch performs.
