Circuit Schematic Symbols
The schematics symbols for most major electrical components can be found in this table. However, each component may have numerous possible representations. In cases where there is more than one common symbol we have tried to give an alternate representation.

Circuit Symbols of Electronic Components
Circuit symbols are used in circuit diagrams which show how a circuit is connected together. The actual layout of the components is usually quite different from the circuit diagram.

Drawings and Sketches
As a Construction Electrician you will be required to read and interpret drawings and specifications, sketches, and electrical diagrams. Before you can work with drawings effectively, you must know how to interpret electrical symbols correctly.

Lessons In Electric Circuits - Circuit Schematic Symbols
Older electrical schematics showed connecting wires crossing, while non-connecting wires "jumped" over each other with little half-circle marks. Newer electrical schematics show connecting wires joining with a dot, while non-connecting wires cross with no dot.
