| Component | American (ANSI) | European (IEC) | | :--- | :--- | :--- | | Resistor | Zigzag line | Rectangle | | Capacitor | Two parallel lines | One curved, one straight line | | NO Pushbutton | Outlined "T" shape | Hand pushing a square | | Relay Coil | Circle or Semicircles | Rectangle with a diagonal line | | Ground | Three decreasing lines | Solid line with three horizontal bars |

Pro Tip: The most common source of error is the Relay Coil. An American engineer sees a rounded symbol and thinks “inductor,” while a European sees a box and thinks “generic load.” The PDF you are searching for highlights this exact discrepancy. Simbologia Electrica Americana Y Europea.pdf

| Componente | Simbología Americana | Simbología Europea | | :--- | :--- | :--- | | Lámpara Incandescente | Un círculo con una "X" en el interior (o a veces con una onda dentro). | Un círculo con una "X" en el interior. (Aquí suelen ser muy similares). | | Luminaria Fluorescente | Un rectángulo largo con líneas internas. | Un rectángulo largo, a menudo con una "H" o signo específico dentro. | | Component | American (ANSI) | European (IEC)

A note you will often find in PDF guides is the blurring of these lines due to CAD software. Pro Tip: The most common source of error is the Relay Coil

While AutoCAD Electrical and other modern EDA (Electronic Design Automation) software usually keep libraries strictly separated by standard, many older diagrams or hand-drawn sketches created by engineers used a "hybrid" style.
