An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may vary from country to country, or engineering ...
IEC 60027-4: Symbols for quantities to be used for rotating electrical machines; IEC 60027-6: Control technology; IEC 60027-7: Physiological quantities and units; A closely related international standard on quantities and units is ISO 31. The ISO 31 and IEC 60027 Standards are being revised by the two standardization organizations in collaboration.
IEC TR 60878 Graphical symbols for electrical equipment in medical practice IEC 60879 Performance and construction of electric circulating fans and regulators IEC 60880 Nuclear power plants – Instrumentation and control systems important to safety – Software aspects for computer-based systems performing category A functions
IEC 113 (Superseded by IEC 750, i.e. IEC 60750.) IEC 750-1983 (AS 3702 is equivalent, but provides extra information.) IEEE 315-1975 / ANSI Standard Y32.2. Annex F: "Cross reference list of Class Designation Letters" compares IEC 113-2:1971 to the IEEE/ANSI standard. * AS 1102 and IEC 60617 for "Graphical Symbols for Electrotechnology".
Reference should be made to codes and standards. For example, IEC 60027, and Letter Symbols in Electrical Technology. Here are tables of widely accepted symbols. They are meant to be a guideline: Using the same symbols for the same things in different articles will increase their consistency, making them easier to understand and to improve.
ISO 14617 Graphical symbols for diagrams is a library of graphical symbols for diagrams used in technical applications. [1] ISO 14617 consists of the following parts: Part 1: General information and indexes; Part 2: Symbols having general application; Part 3: Connections and related devices; Part 4: Actuators and related devices
Library of electrical symbols for diagramming with Inkscape. There is a (small but extensible) library of symbols available. Creating diagrams using this template is slightly slower than in specialised programs, but it is very flexible and produces nice vector output. A simple symbol library based on well-known package, circuit_macros
A less common symbol is simply a series of peaks on one side of the line representing the conductor, rather than back-and-forth. Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle ...
