Mandatory Condition (specific action required by operator).

Designing control panels according to IEC 60073 offers several clear advantages for manufacturers and facility operators:

IEC 60073 provides the universal rules for assigning meanings to visual, acoustic, and tactile signals. Whether you are designing a simple push-button or a complex SCADA screen, this standard ensures that an operator can immediately recognize a machine's state and know exactly how to respond. iec 60073 pdf

For pushbuttons and switches, the standard defines:

The scope of IEC 60073 is extensive, covering all three primary sensory channels through which a machine communicates with its operator: Mandatory Condition (specific action required by operator)

Standardizing that emergency buttons are red, often with a yellow background, to ensure instant identification.

Signals that conditions are outside normal limits but do not pose an immediate danger yet. It prompts the operator to monitor or intervene to prevent escalation. For pushbuttons and switches, the standard defines: The

He was a standards engineer by trade—soft-spoken, wearied by committee meetings and the slow churn of consensus. His name was Marco. For years he’d watched operators misread indicator lights, technicians misinterpret instrument panels, and managers shrug at costly mistakes. One rainy evening, with the plant’s generators thudding like a distant heartbeat, Marco pulled IEC 60073 from the shelf and opened the world it described: a system of tactile, visual, and auditory symbols—an agreed grammar for how devices speak to people.

General information. Can indicate power availability, direction of travel, or online status. None; informational only. 2. Actuators (Pushbuttons and Switches)

Frequently used for general start/stop functions where safety is not the primary concern (e.g., White for Start, Black for Stop). 3. Supplementary Coding: Shape and Position

Used to draw attention to an abnormal but non-critical change of state.
