14+ Schematic Relay Symbols Background. The internal schematic of the solid state relay is shown in the data sheet, but showing all of the internal components in the schematic is not necessary and would be more confusing than a single symbol. An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors.
Schematic symbols have been standardized by two different guidelines:
Applications of relays in electronic circuits. Available in svg, png, jpg, dxf & dwg formats. There is a quite adequate collection of symbol for electrical, electronic circuit. Click on each link given below to view.
