From Wikipedia, the free encyclopedia
An electronic symbol is a pictogram used
to represent various electrical and
electronic devices (such as wires, batteries,
resistors, and transistors) in a schematic
diagram of an electrical or electronic
circuit. These symbols can (because of
remaining traditions) vary from country to
country, but are today to a large extent
internationally standardized. Some symbols
represent components (such as vacuum
tubes) which ceased to be used routinely as
newer technologies were introduced.

There are several national and international standards for graphical symbols in circuit diagrams, in particular:
IEC 60617 (also known as British Standard BS 3939).
ANSI standard Y32.2 (also known as IEEE Std 315).
IEEE Std 91/91a: graphic symbols for logic functions (used in digital electronics). It is referenced in
ANSI Y32.2/IEEE Std 315.
Australian Standard AS 1102.
Different symbols may be used depending on the discipline using the drawing. For example, lighting and
power symbols used as part of architectural drawings may be different from symbols for devices used in
electronics. National and local variations to international standards also exist.
Symbols shown are typical examples, not a complete list.[1]
