Edraw Max, an electrical diagramming program, was the first software to demonstrate standard electrical symbols on computer screens.
Electrical symbols are used to represent electrical and electronic devices in schematic diagrams. There are different country-specific standards, IEC (British), ANSI, and AS (Australian Standard), that define the symbols used in circuit diagrams across the world. However, today most of the symbols are internationally standardized. We have provided a list of the most commonly used electrical symbols in electrical drawings.
