Define what a yellow push button communicates\u2014and what it does not<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Yellow is commonly used in panel design to draw attention, often where an operator should notice an abnormal condition or use a specific intervention. That description is deliberately conditional. The physical colour does not carry a complete, universal instruction by itself.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">A yellow operator should never force an operator to guess whether it starts, stops, resets, acknowledges, tests, or changes a machine state. The meaning is established by the surrounding HMI design and the documented control philosophy. It is also unsafe to infer an emergency-stop function merely from a yellow button.<\/p>\n<table style=\"width:100%;border-collapse:collapse\">\n<thead>\n<tr>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Input around a yellow control<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Why it matters<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Do not infer<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Nearby text or symbol<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Gives the intended action a readable name<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">That yellow alone explains the action<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Machine state<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Explains when the control may be used<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">That it is always a start or stop command<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Risk assessment and instructions<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Aligns the control with the intended protective strategy<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">That colour replaces safety design<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Project colour convention<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Creates consistency across the machine<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">That every market uses one identical meaning<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"margin:0 0 16px;line-height:1.7\">Le <a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/webstore.iec.ch\/en\/publication\/587\" target=\"_blank\" rel=\"noopener\">IEC 60073 publication<\/a> covers coding principles for indicators and actuators. Use applicable editions and local rules with the machine documentation rather than copying a single colour convention without context.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"part-2-link-colour-to-a-nearby-label-symbol-and-machine-state\">Part 2. Link colour to a nearby label, symbol, and machine state<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">The strongest panel message combines a visible control, a concise label or recognized symbol, and behaviour that matches what the operator sees on the machine. A yellow control used for a fault acknowledgement, for example, should have a clear legend and an understandable condition in the control logic. If the function changes by operating mode, the documentation and HMI should make that change visible.<\/p>\n<blockquote>\n<p style=\"margin:0 0 16px;line-height:1.7\"><strong>Important:<\/strong> Do not use a yellow push button as the sole explanation of an action. The <a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/webstore.iec.ch\/en\/publication\/2157\" target=\"_blank\" rel=\"noopener\">IEC 60447 resource<\/a> addresses actuator principles; the final function, legend, and placement should be checked against the project\u2019s machine-control documentation.<\/p>\n<\/blockquote>\n<p style=\"margin:0 0 16px;line-height:1.7\">Keep wording short enough to be read at the operating position. Avoid generic labels such as \u201cRESET\u201d if the action can have several consequences; use the approved machine terminology. Where a pictogram is used, confirm that it matches the operation and is legible after the panel finish, lighting, and viewing angle are considered.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">For a broader discussion of colour as one layer of the interface, see the <a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/onpowbutton.com\/fr\/news\/push-button-color-coding-guide\/\">push button color coding guide<\/a>. That supporting article does not replace the project-specific label review described here.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"part-3-keep-operator-controls-distinct-from-indicator-lights\">Part 3. Keep operator controls distinct from indicator lights<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">An illuminated push button can combine a manually operated actuator with light output, while a pilot light is primarily an indication device. On a busy panel, users should be able to distinguish \u201cpress this\u201d from \u201cobserve this\u201d without studying the wiring diagram. Shape, label, location, and illumination behaviour all contribute to that distinction.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Do not assume that an illuminated yellow cap has the same message as a separate yellow indicator. A flashing pattern, steady light, and momentary or maintained operator action can each carry different implications. Define the function in the I\/O list and the control narrative before choosing the hardware configuration.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Le <a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/onpowbutton.com\/fr\/news\/ring-vs-dot-led-illumination-push-button-switches\/\">ring versus dot LED illumination guide<\/a> is useful when the selected control needs an illuminated form. Confirm illumination voltage, lens style, wiring, and operation for the actual SKU rather than applying a category image as a specification.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"part-4-place-yellow-controls-where-an-abnormal-condition-action-is-understood\">Part 4. Place yellow controls where an abnormal-condition action is understood<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Place a yellow operator near the related machine information and within the reach path used for that action. A control that acknowledges a condition should not be separated from the relevant status display or placed where it can be confused with a normal run command. Consistent spacing and label alignment make this relationship easier to understand.<\/p>\n<figure style=\"margin:26px 0;text-align:center\"><img decoding=\"async\" style=\"max-width:640px;width:100%;height:auto;display:block;margin:0 auto;border-radius:8px\" alt=\"ONPOW three-position plastic push-button enclosure for panel placement planning\" src=\"https:\/\/onpowbutton.com\/wp-content\/uploads\/2026\/08\/yellow-push-button-status-panel-layout.webp\" \/><\/figure>\n<p style=\"margin:0 0 16px;line-height:1.7\">IEC 61310-3 addresses the location and operation of actuators. In a practical review, check viewing angle, gloved use, accidental-operation exposure, and whether another nearby control has a similar appearance. A colour choice is more useful when the surrounding layout reinforces the same message.<\/p>\n<table style=\"width:100%;border-collapse:collapse\">\n<thead>\n<tr>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Panel review element<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Question to resolve<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Design impact<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Location<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Can the operator see the relevant state before pressing?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Reduces ambiguous action<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Label<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Is the action readable and unambiguous?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Supports training and troubleshooting<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Adjacent controls<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Could another button be pressed by mistake?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Improves spacing and grouping<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Illumination behaviour<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Is steady, flashing, or off state defined?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Keeps indication consistent<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Operating mode<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Does the control mean the same thing in every mode?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">May require mode-specific indication<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"margin:0 0 16px;line-height:1.7\">For a panel-wide placement review, use the <a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/onpowbutton.com\/fr\/news\/push-button-control-panel-layout-guide\/\">push-button control panel layout guide<\/a>.

It is not a universal instruction by itself.<\/p>\n<h3 style=\"margin:28px 0 12px\">Is a yellow button always a reset button?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">No. A yellow operator may be used for different documented functions. Use an explicit label and the approved control narrative to define the action.<\/p>\n<h3 style=\"margin:28px 0 12px\">Can I use yellow for an emergency stop?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Do not infer an emergency-stop function from yellow alone. Emergency-stop design, identification, and suitability must follow the applicable machine-safety requirements and the approved design documentation.<\/p>\n<h3 style=\"margin:28px 0 12px\">Should a yellow illuminated push button replace a pilot light?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Not automatically. An illuminated push button is an actuator with light output, while a pilot light is primarily an indicator. Choose the form that makes the required operator action and machine state clear.<\/p>\n<h3 style=\"margin:28px 0 12px\">What information should be on the panel drawing?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Show the exact label or symbol, location, cutout, panel thickness, intended operator action, illumination behaviour, and relevant circuit or I\/O reference.
