About this app

Industrial Electrical Symbols puts a complete, standards-accurate library of electrical and electronic schematic symbols in your pocket. Whether you're reading a wiring diagram on the job, designing a control panel, studying for an exam, or brushing up on ladder logic, the symbol you need is organized, searchable, and ready.
Browse electrical symbols across passive components, semiconductors, switches, protection devices, relays and contactors, and more — each with its reference designator, description, and engineering notes.
⚡ WHY YOU'LL LOVE IT

Four standards in one app: instantly switch between IEC 60617, ANSI/IEEE, DIN, and NEMA so your symbols always match your project and region.
Clean, organized library: components grouped into clear categories with a fast, modern interface.
Detailed symbol references: see standard variants, reference designators, component IDs, function, typical use, polarity, related symbols, and engineering notes — all in one place.
Build your personal library: save frequently used components for Quick Access and keep your essentials one tap away.
Test your knowledge: interactive symbol quizzes with instant feedback and clear explanations help you learn faster and retain more.
Powerful search: find any symbol in seconds.
Dark, light, and system themes: easy to read in the field or in the workshop.

📐 EVERY SYMBOL, EVERY STANDARD
Electrical drawings differ across the world — a resistor, a circuit breaker, or a contactor can look completely different in IEC versus ANSI. This app shows you the correct symbol for IEC 60617, ANSI/IEEE, DIN, and NEMA, so you never misread a schematic again.
🔧 WHO IT'S FOR

Electricians and industrial maintenance technicians

📚 LEARN AND REFERENCE IN ONE PLACE
Look up a symbol the moment you need it, save the ones you use most, and sharpen your skills with quizzes between jobs or study sessions. From capacitors, inductors, resistors, and diodes to fuses, switches, relays, transistors, thyristors, potentiometers, and heating elements — it's all here, drawn to the standard you choose.
🔎 TOPICS COVERED
Electrical symbols, schematic symbols, circuit symbols, wiring diagram symbols, IEC 60617, ANSI/IEEE, DIN, NEMA, passive components, semiconductors, switches, protection devices, relays and contactors, control panel and ladder logic references.
We're constantly improving the app and adding new symbols and features.
