Basic electrical and electronic symbols

electrical symbols

The main electronic and electrical symbols represent functions, components, devices, and circuits in electrical and electronic diagrams. They all belong to the most common and widely used standards in the world.

These basic electrical and electronic symbols are represented by their generic symbol. For some representations, you can access their family in the related link in the “+ symbol” attached to the device name.
