The International Electrotechnical Commission (IEC) symbols, also known as IEC 60617 (British Standard BS 3939), are an international, standardised system used to represent various devices, including pilot lights, relays, timers, and switches, in electrical schematic diagrams.
The IEC standardizes symbols for electronic equipment and electrical components to ensure that circuit diagrams can be read and recognized in many different countries. With the mass production of many devices around the world, having a uniform design for all schematics ensures that engineers and manufacturers are working to the same standards. It's also necessary to devise, standardize, and introduce new symbols for the more advanced technology that is now in circulation.
Manually drawing and designing IEC symbols for electrical drawings can be difficult and time-consuming. Fortunately, you can skip the hassle entirely with Capital X Panel Designer! This electrical CAD software provides you with an extensive library of pre-made IEC electrical schematic symbols that you can simply drag and drop into your circuit drawing. Best of all, Capital X Panel Designer is easy to use, ensuring that you can quickly update your schematics to match current plan designs.
