: Use standard IEC 60417 symbols (like I for On and O for Off) directly on or next to the actuators.

When you purchase from these sources, you are buying an identical document (often with a national prefix, e.g., BS EN 60073:2002) and are guaranteed to receive the correct, up-to-date version.

Truth: For indicators , red means danger/fault; green means normal. For actuators , red means stop; green means start. But for a reset button, blue is preferred.

The standard assigns specific meanings to visual and physical attributes. The primary coding methods include colors, shapes, and acoustic signals, with color being the most widely recognized. 1. Color Coding for Indicators (Lights and Screens) iec 60073 pdf

IEC 60073 is the international standard that sets the rules for how we use colors, shapes, sounds, and touch to communicate with machines

Neutral colors used for general information not directly tied to safety or hazards. 2. Color Coding for Actuators (Pushbuttons and Switches)

For actuators, red is used for functions. However, exceptions are allowed when the color red is not available. : Use standard IEC 60417 symbols (like I

Used to initiate normal operation, start a process, or energize a circuit.

Safety and clarity are critical in industrial automation and electrical engineering. Human operators rely on visual and tactile cues to understand machine states instantly. The International Electrotechnical Commission (IEC) established the standard to unify these cues globally.

The most recognizable part of the standard is its codification of colors used on control panels and equipment. The standard works primarily with seven colors for indicating devices and actuators (controls like buttons). For actuators , red means stop; green means start

The standard also recognizes that for universal communication. Color-blind operators, varying lighting conditions, and different cultural contexts all necessitate supplementary coding methods. IEC 60073 therefore specifies coding by:

| Actuator Function | Permitted Colors | Special Rules | |------------------|-----------------|---------------| | Emergency/Normal (stop/off) | Red | Exceptions allowed when red not available | | STOP/OFF | White, grey, black | Red can be used, but green is not permitted | | START/ON | White, grey, black | Green can be used, but red is not permitted | | RESET | Blue, white, black, grey | Blue is the preferred color |

The standard is available in multiple languages:

Reserved exclusively for stopping, de-energizing, or emergency shutdown functions.
