The supplier maps your checklist to a stock or lightly configured SKU.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\"><strong>Custom modification<\/strong> asks for a change that is not a simple option code: a different actuator geometry, a non-standard panel cutout or thread length, a pre-wired harness length, a laser-etched legend, a contact block not offered on the catalog page, or extra sealing beyond the published description. That path needs drawings, tolerances, approval samples, and explicit \u201cfeasibility TBD\u201d flags\u2014not a color code alone.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Write the RFQ in two labeled blocks: <strong>Configuration fields<\/strong> (what you can select from published options) and <strong>Modification fields<\/strong> (what must be engineered or tooled). If every line sits in the first block, you are buying a configured series, not a modified switch.

Review the finished opening, the panel thickness that sets retention hardware, and the rear keep-out that protects harness access as three separate lines.<\/p>\n<figure style=\"margin:1.5rem 0;\">\n<p><img decoding=\"async\" src=\"https:\/\/lemaele.com\/wp-content\/uploads\/2026\/08\/rfq-img1-assembly.webp\" alt=\"LEMA PBS Series yellow rectangular push button assembly showing mounting nut and rear micro switch\" style=\"max-width:640px;height:auto;\" title=\"\"><\/p>\n<\/figure>\n<p style=\"margin:0 0 16px;line-height:1.7\">Ask for a front view and a section that shows neighboring ducts, DIN rails, or covers. Service access belongs in the same review: if terminals cannot be reached after the door closes, the sample will pass on a bench and fail on the machine.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">When the job is truly custom, mechanical lines must state <strong>delta<\/strong>, not adjectives. A deeper bezel or a non-catalog cutout still needs a dimension or a reference drawing. Do not invent a mounting diameter when the drawing is open\u2014record the open item, then close it against the supplier drawing for the exact configuration you intend to sample.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"custom-modification-fields-beyond-catalog-options\">Custom Modification Fields Beyond Catalog Options<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">These are the lines buyers skip when they only copy color codes from a product page. Each belongs in the <strong>Modification fields<\/strong> block with its own evidence attachment.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\"><strong>Contact form or block change.<\/strong> State the required NO\/NC arrangement, whether you need a different contact block than the series default, and whether the change is for the switching contacts only or includes auxiliary poles. Attach the circuit diagram; do not assume the supplier will \u201cmatch the old part\u201d from a photo.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\"><strong>Mounting and panel interface change.<\/strong> Specify cutout diameter or square, panel thickness range, thread length or nut style, bezel projection, and any anti-rotation requirement. If the front looks standard but the rear body is longer, show the section view with the longest wire bend radius you will allow.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\"><strong>Wire length, termination, and harness.<\/strong> Pre-wired leads are a modification, not a color option. Give lead length, gauge, insulation class if your harness standard requires it, connector type or bare tinned ends, and strain-relief expectations. A wrong lead length often fails at final assembly even when the head fits the hole.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\"><strong>Legend, imprint, or marking.<\/strong> Provide artwork for laser etch, pad print, or molded legend\u2014font, language, symbol set, and location on the actuator or bezel. Marking errors are expensive because they pass electrical sample review and fail at customer acceptance.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\"><strong>Sealing or protection beyond published series data.<\/strong> Describe the exposure (wash-down zone, outdoor cabinet, dusty plant aisle) and ask the supplier to confirm which sealing approach applies to the <strong>exact<\/strong> configuration\u2014not to the family name. Do not paste an IP code into the RFQ unless your internal standard already selected that code and you can tie it to test method and mounting.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">If a line cannot be supported yet, label it <strong>feasibility TBD<\/strong> and keep it in the modification block. Hiding it inside \u201cstandard PBS\u201d language is how quotes arrive without the engineering you thought you bought.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"action-contacts-and-control-circuit-language\">Action, Contacts, and Control-Circuit Language<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Action type and contact form must match the control document; software or wishful naming cannot convert one hardware behavior into another.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Momentary action means the circuit changes only while the operator is pressed. Maintained \/ latching action keeps the selected state until another operation changes it. On the <a style=\"color:#f27c00;text-decoration:underline\" href=\"https:\/\/forum.arduino.cc\/t\/momentary-button-as-latching-button\/536630\" target=\"_blank\" rel=\"noopener\">Arduino Forum<\/a>, builders regularly try to force latching behavior from momentary hardware and discover the device still springs back\u2014exactly the mismatch an RFQ should prevent by stating the action in plain words.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Contact language should follow the circuit, not the catalog nickname. NO \/ NC contacts\u2014normally open and normally closed forms, including combinations such as 1NO+1NC\u2014define how the resting state relates to the actuated state. Map the requested form to terminal assignments on the wiring drawing before you ask for price.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">For electrical duty, industrial control-circuit devices are commonly specified under the <a style=\"color:#f27c00;text-decoration:underline\" href=\"https:\/\/webstore.iec.ch\/en\/publication\/65935\" target=\"_blank\" rel=\"noopener\">IEC 60947-5-1<\/a> family. Public text for the standard explains that contact elements are classified by <strong>utilization categories<\/strong>\u2014shorthand for how hard a contact is expected to switch a given load type.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">In RFQ language, ask the supplier to mark the proposed configuration against the relevant category on the datasheet\u2014for example <strong>AC-15<\/strong> for AC control-circuit loads and <strong>DC-13<\/strong> for DC control-circuit loads\u2014rather than copying a voltage number from an unrelated circuit. If your load is inductive, inrush-heavy, or low-level, say so in the same line so the category question is not answered against the wrong duty.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Do not paste a voltage or current into the RFQ unless your circuit document already owns that number. The utilization question is how procurement asks for proof; it is not permission to invent a rating.<\/p>\n<figure style=\"margin:1.5rem 0;\">\n<p><img decoding=\"async\" src=\"https:\/\/lemaele.com\/wp-content\/uploads\/2026\/08\/rfq-img3-side.webp\" alt=\"LEMA PBS Series push button switch side view for contact and mounting review\" style=\"max-width:640px;height:auto;\" title=\"\"><\/p>\n<\/figure>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"when-illumination-belongs-in-the-rfq\">When Illumination Belongs in the RFQ<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Illumination is a separate circuit decision from the switching contacts, even when both sit in one <strong>illuminated push button<\/strong> operator. LED illumination belongs in the RFQ only when the panel legend needs a locator or status light at the same station.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">A <a style=\"color:#f27c00;text-decoration:underline\" href=\"https:\/\/en.wikipedia.org\/wiki\/Push-button\" target=\"_blank\" rel=\"noopener\">push-button<\/a> can carry a pilot light so operators see machine state, but the energy that lights the lens is often tied to process feedback rather than to the switch contacts themselves. Specifying \u201cilluminated\u201d without color, supply expectation, and whether the lamp is a locator or a status signal invites the wrong LED option.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Write three lines when light matters: whether LED is required, which color the panel legend expects, and which supply the indication circuit uses. Treat lamp voltage or current as part of the <strong>indication block<\/strong>, not as an afterthought on the contact block.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">If the design does not need a lamp, say so explicitly. Silence is often read as \u201csupplier choice,\u201d which is how mismatched illuminated samples appear.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"environment-vibration-and-sealing-in-the-rfq\">Environment, Vibration, and Sealing in the RFQ<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">\u201cExposure notes\u201d is not an environment specification.

Treat that as a configuration question with a feasibility answer\u2014not as a blanket series claim.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">When the modification block is non-empty, send the engineering package first. A series page helps buyers understand available configuration codes; it does not substitute for the modification evidence in the RFQ.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"send-a-complete-package-via-contact-us\">Send a Complete Package via Contact Us<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">After the configuration and modification blocks are filled\u2014or honestly marked open\u2014send the RFQ, drawings, utilization questions, environment fields, and sample plan through <a style=\"color:#f27c00;text-decoration:underline\" href=\"https:\/\/lemaele.com\/fr\/contact-us\/\">Contactez-nous<\/a>.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Attach the panel package, the action and contact decisions, the indication block if used, the golden-sample rule, and any configuration codes you already selected. Label open items so engineering and purchasing share the same risk list.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">A complete, honest package is faster to quote than a polished email that hides unresolved fit, duty, or modification questions.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"faq\">FAQ<\/h2>\n<h3 style=\"margin:28px 0 12px\">What is the difference between configuring a series and requesting a custom modification?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Configuration selects published options on an existing family\u2014color, LED choice, contact arrangement already offered. Modification asks for engineering or tooling changes such as cutout size, wire length, imprint artwork, contact block changes, or sealing beyond published data. Split them in the RFQ so the quote matches the job.<\/p>\n<h3 style=\"margin:28px 0 12px\">Which utilization category should appear on a push button datasheet?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Under IEC 60947-5-1, contacts are classified by utilization categories that describe load duty\u2014commonly <strong>AC-15<\/strong> for AC control circuits and <strong>DC-13<\/strong> for DC control circuits. Ask the supplier to show the category on the datasheet for the <strong>exact<\/strong> configuration you will buy, tied to your stated load type\u2014not a generic family sheet.<\/p>\n<h3 style=\"margin:28px 0 12px\">How should vibration, temperature, and sealing enter the RFQ?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Write separate lines for temperature band, vibration or shock class, moisture or wash exposure, and contaminants. Ask the supplier to confirm sealing and materials against that environment for the approved configuration. Do not copy an IP code unless your internal standard already selected the code and test context.<\/p>\n<h3 style=\"margin:28px 0 12px\">Why must lamp and contact circuits stay in separate RFQ blocks?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">The switching contacts and the indicator lamp often use different supplies and failure modes. Mixing them in one vague \u201cilluminated switch\u201d line produces samples that fit the hole but wire incorrectly. State lamp need, color, and supply in the indication block; keep NO\/NC logic in the contact block.<\/p>\n<h3 style=\"margin:28px 0 12px\">What makes a golden sample different from naming a series?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">A golden sample is a labeled unit and drawing revision approved for fit, continuity, marking, and modification delta in <strong>your<\/strong> panel. Production releases point to that sample\u2014not to \u201cPBS Series\u201d or any family nickname alone.<\/p>\n<h3 style=\"margin:28px 0 12px\">Which drawing views belong in a panel-mount custom RFQ?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Include front view, section for rear keep-out, neighboring parts, wire-exit direction, and any imprint artwork. Custom modification lines need dimensions or deltas against the catalog reference, not adjectives alone.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"references\">R\u00e9f\u00e9rences<\/h2>\n<ol style=\"margin:0 0 18px 1.2em;line-height:1.7\">\n<li style=\"margin:0 0 8px\">\n<p style=\"margin:0 0 16px;line-height:1.7\"><a style=\"color:#f27c00;text-decoration:underline\" href=\"https:\/\/webstore.iec.ch\/en\/publication\/65935\" target=\"_blank\" rel=\"noopener\">IEC 60947-5-1:2024 \u2014 Electromechanical control circuit devices<\/a> \u2014 standard family covering push-buttons as control circuit devices.<\/p>\n<\/li>\n<li style=\"margin:0 0 8px\">\n<p style=\"margin:0 0 16px;line-height:1.7\"><a style=\"color:#f27c00;text-decoration:underline\" href=\"https:\/\/law.resource.org\/pub\/in\/bis\/S05\/is.iec.60947.5.1.2003.pdf\" target=\"_blank\" rel=\"noopener\">IS\/IEC 60947-5-1 (2003) public text<\/a> \u2014 push-button definition and contact-form \/ utilization-category framework.<\/p>\n<\/li>\n<li style=\"margin:0 0 8px\">\n<p style=\"margin:0 0 16px;line-height:1.7\"><a style=\"color:#f27c00;text-decoration:underline\" href=\"https:\/\/en.wikipedia.org\/wiki\/Push-button\" target=\"_blank\" rel=\"noopener\">Push-button (Wikipedia)<\/a> \u2014 industrial operator and pilot-light context.<\/p>\n<\/li>\n<li style=\"margin:0 0 8px\">\n<p style=\"margin:0 0 16px;line-height:1.7\"><a style=\"color:#f27c00;text-decoration:underline\" href=\"https:\/\/www.eevblog.com\/forum\/beginners\/wiring-4-pin-push-button-in-kicad\/\" target=\"_blank\" rel=\"noopener\">Wiring 4-pin push button in KiCad (EEVblog)<\/a> \u2014 pinouts vary; documentation or measurement required before freezing design.<\/p>\n<\/li>\n<li style=\"margin:0 0 8px\">\n<p style=\"margin:0 0 16px;line-height:1.7\"><a style=\"color:#f27c00;text-decoration:underline\" href=\"https:\/\/forum.arduino.cc\/t\/momentary-button-as-latching-button\/536630\" target=\"_blank\" rel=\"noopener\">Momentary button as latching button (Arduino Forum)<\/a> \u2014 action type must be specified in hardware; software cannot permanently substitute maintained behavior.<\/p>\n<\/li>\n<\/ol>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Liste de contr\u00f4le pour une demande de devis (RFQ) concernant un interrupteur \u00e0 bouton-poussoir personnalis\u00e9 : distinguer la configuration des modifications, pr\u00e9ciser les conditions d\u2019utilisation AC-15\/DC-13 et approuver un \u00e9chantillon de r\u00e9f\u00e9rence avant la production.<\/p>","protected":false},"author":6,"featured_media":1170,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-1176","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"_links":{"self":[{"href":"https:\/\/lemaele.com\/fr\/wp-json\/wp\/v2\/posts\/1176","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lemaele.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lemaele.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lemaele.com\/fr\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/lemaele.com\/fr\/wp-json\/wp\/v2\/comments?post=1176"}],"version-history":[{"count":3,"href":"https:\/\/lemaele.com\/fr\/wp-json\/wp\/v2\/posts\/1176\/revisions"}],"predecessor-version":[{"id":1179,"href":"https:\/\/lemaele.com\/fr\/wp-json\/wp\/v2\/posts\/1176\/revisions\/1179"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/lemaele.com\/fr\/wp-json\/wp\/v2\/media\/1170"}],"wp:attachment":[{"href":"https:\/\/lemaele.com\/fr\/wp-json\/wp\/v2\/media?parent=1176"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lemaele.com\/fr\/wp-json\/wp\/v2\/categories?post=1176"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lemaele.com\/fr\/wp-json\/wp\/v2\/tags?post=1176"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
