Define the \u03c630 Interface Before Selecting a Product<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">The \u201c30mm\u201d in a 30mm push button switch normally refers to the mounting interface when the manufacturer lists an installation or cutout diameter of \u03c630. It does not mean the front actuator is exactly 30mm wide. For example, product catalogues can show a 30mm cutout alongside a larger operator head. Measure the finished hole, not the front bezel.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Start with the panel drawing and record the actual opening, tolerance, thickness, material, coating, and any anti-rotation feature. On an existing enclosure, measure after paint, plating, or powder coating, and inspect from the rear if the old device can be removed safely. On a new enclosure, place the \u03c630 callout and its keep-out zones in the mechanical layout before selecting terminal hardware.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">The mechanical interface should lead the process because it is the least forgiving part to change after the panel is made. A product family can offer different head shapes, illumination, operation, or terminals, yet all of those choices remain secondary if the mounting body cannot pass through the panel or the retaining method cannot be installed.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"part-2-treat-upsizing-from-19mm-or-22mm-as-a-panel-change\">Part 2. Treat Upsizing From 19mm or 22mm as a Panel Change<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Moving from 19mm or 22mm to 30mm is not a drop-in operator substitution. A \u03c630 mounting body is larger than either opening. Enlarging an existing hole changes the panel design and may affect edge distance, labels, adjacent devices, stiffness, seal geometry, and rear wiring space. Use a documented mechanical change or an approved interface solution; do not rely on a faceplate to conceal a mismatched opening.<\/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\">Existing condition<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">What it tells you<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Responsible next step<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">New panel requires \u03c630<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">The interface is already specified<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Obtain the candidate\u2019s mounting drawing and rear dimensions<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Existing \u03c619 hole<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">The original interface is smaller<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Review the <a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/onpowbutton.com\/fr\/news\/19mm-push-button-switch-guide\/\">19mm panel-interface guide<\/a> or engineer a panel change<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Existing \u03c622 hole<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">The original interface is still smaller<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Start with the <a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/onpowbutton.com\/fr\/news\/22mm-push-button-switch-guide\/\">22mm panel-interface guide<\/a> before enlarging the panel<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Existing \u03c630 hole<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">The physical interface is compatible in principle<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Confirm thickness, retention, rear clearance, and configuration<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Only the bezel was measured<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">The cutout remains unknown<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Measure the bore and inspect the existing mounting hardware<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"margin:0 0 16px;line-height:1.7\">The front layout needs its own review after the interface is chosen.

Reserve the Rear Envelope<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">The rear envelope is the space behind the panel required by the body, retaining hardware, terminal, wire exit, wire bend, and service procedure. A panel can accept a \u03c630 body and still fail the assembly review because a rail, PCB, door, connector, or cable duct occupies the wiring zone.<\/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 exploded push button view for reviewing mounting components and rear clearance\" src=\"https:\/\/onpowbutton.com\/wp-content\/uploads\/2026\/07\/waterproof-push-button-switch-exploded-view.webp\" \/><\/figure>\n<p style=\"margin:0 0 16px;line-height:1.7\">Create a side-section drawing from the panel rear surface.

The exact answer always belongs to the product drawing and the panel\u2019s own harness plan.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"part-4-choose-operation-and-contact-logic-separately\">Part 4. Choose Operation and Contact Logic Separately<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Operation describes the actuator behavior. A <strong>momentary<\/strong> operator returns when released. A <strong>latching<\/strong> operator retains a changed state until it is actuated again. Select one based on the intended command logic and the precise configuration that the product page offers.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Contact notation describes a different layer. <strong>1NO1NC<\/strong> means one normally open contact and one normally closed contact in the defined normal condition. It is not a statement about terminal direction, LED wiring, or the circuit function of the complete machine. Verify the exact diagram and terminal markings when preparing the harness.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Write the control requirement in plain language before searching a catalogue:<\/p>\n<ol style=\"margin:0 0 18px 1.2em;line-height:1.7\">\n<li style=\"margin:0 0 8px\">What action must occur while the actuator is held?<\/li>\n<li style=\"margin:0 0 8px\">What state must exist after it is released?<\/li>\n<li style=\"margin:0 0 8px\">How many NO and NC contacts are required?<\/li>\n<li style=\"margin:0 0 8px\">Is an indicator needed, and how will it be powered or controlled?<\/li>\n<li style=\"margin:0 0 8px\">What exact terminal system will the panel harness use?<\/li>\n<\/ol>\n<p style=\"margin:0 0 16px;line-height:1.7\">This approach prevents a common sourcing error: buying a mechanically correct 30mm operator with the wrong behavior or termination. It also prevents an article about a physical interface from making a load-use conclusion that the exact product documentation has not established.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"part-5-compare-screw-terminal-and-pin-terminal-evidence\">Part 5. Compare Screw-Terminal and Pin-Terminal Evidence<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Terminal type affects both wiring and rear clearance. It must be taken from the exact selected page, not inferred from a 30mm family name. ONPOW\u2019s verified product pages provide a useful example of why this distinction matters.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">The GQ30-L-11\/S page lists a <strong>borne \u00e0 vis<\/strong>. The LCA30-11\/S and LCA30-11E\/S pages list a <strong>switch pin terminal (4.8 \u00d7 0.5mm)<\/strong>. Those are different documented termination routes, so they should be matched to the approved wiring method and rear keep-out zone. The three pages also list \u03c630, 1NO1NC, and momentary\/latching fields, but the terminal evidence must remain tied to the individual page.<\/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\">Question<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">GQ30-L-11\/S page<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">LCA30-11\/S page<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">LCA30-11E\/S page<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Diam\u00e8tre d'installation<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">\u03c630<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">\u03c630<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">\u03c630<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Contact structure<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">1NO1NC<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">1NO1NC<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">1NO1NC<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Operation mode<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Momentan\u00e9\/Bi-stable<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Momentan\u00e9\/Bi-stable<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Momentan\u00e9\/Bi-stable<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Terminal evidence<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Borne \u00e0 vis<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Switch pin terminal, 4.8 \u00d7 0.5mm<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Switch pin terminal, 4.8 \u00d7 0.5mm<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Illumination listing<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Not used as an illumination claim here<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Non-illuminated page route<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Ring illuminated; page lists LED colors and voltages<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"margin:0 0 16px;line-height:1.7\">For front-condition language, read <a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/onpowbutton.com\/fr\/news\/ip-vs-ik-ratings-industrial-push-button-switches\/\">IP and IK selection guide<\/a> alongside the exact product page.

For the ONPOW pages covered here, the listed installation diameter is \u03c630mm.<\/p>\n<h3 style=\"margin:28px 0 12px\">Can I install a 30mm push button in a 22mm or 19mm hole?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Not as a direct substitution. A \u03c630 mounting body needs a \u03c630 interface, so changing from a smaller hole requires a documented panel modification or approved interface solution.<\/p>\n<h3 style=\"margin:28px 0 12px\">Is 30mm the button face diameter?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Not necessarily. The bezel can be wider than the mounting opening. Confirm the installation diameter and all front dimensions on the product drawing.<\/p>\n<h3 style=\"margin:28px 0 12px\">How much rear depth should I allow for a 30mm switch?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Use the exact product drawing and add space for retaining hardware, terminals, wire bend, and service access. There is no reliable generic depth for every 30mm configuration.<\/p>\n<h3 style=\"margin:28px 0 12px\">What does 1NO1NC mean?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">It means one normally open and one normally closed contact in the defined normal condition. It does not replace the model\u2019s wiring diagram or terminal identification.<\/p>\n<h3 style=\"margin:28px 0 12px\">Does GQ30-L-11\/S have screw terminals?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Yes. The verified ONPOW GQ30-L-11\/S page lists \u201cScrew Terminal.\u201d Confirm the selected configuration and rear wiring space before ordering.<\/p>\n<h3 style=\"margin:28px 0 12px\">Are the LCA30 pages screw-terminal versions?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">No. The verified LCA30-11\/S and LCA30-11E\/S pages list a switch pin terminal sized 4.8 \u00d7 0.5mm.<\/p>\n<h3 style=\"margin:28px 0 12px\">Can Ith 20A be read as a direct-load rating?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">No. GQ30-L-11\/S lists Ith 20A, but that field alone does not state a validated load type, utilization category, motor duty, switching frequency, or direct-load recommendation.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\">References<\/h2>\n<ul style=\"margin:0 0 18px 1.2em;line-height:1.7\">\n<li style=\"margin:0 0 8px\"><a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/webstore.iec.ch\/en\/publication\/65935\" target=\"_blank\" rel=\"noopener\">IEC 60947-5-1: electromechanical control circuit devices<\/a><\/li>\n<li style=\"margin:0 0 8px\"><a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/webstore.iec.ch\/en\/publication\/2452\" target=\"_blank\" rel=\"noopener\">IEC 60529: IP Code<\/a><\/li>\n<li style=\"margin:0 0 8px\"><a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/webstore.iec.ch\/en\/publication\/71109\" target=\"_blank\" rel=\"noopener\">IEC 62262: IK Code<\/a><\/li>\n<li style=\"margin:0 0 8px\"><a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/www.legacy.altechcorp.com\/PDFS\/30mmPB-TechSpecs.pdf\" target=\"_blank\" rel=\"noopener\">Altech 30mm push button technical catalogue<\/a><\/li>\n<\/ul>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>A 30mm push button switch begins with a \u03c630 panel interface.
