What does a dual push button switch do on a 22mm panel?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">A dual operator groups two separate manual actions in a compact station. In machine-control language, the actions are often labelled Start and Stop or use green and red caps. The operator does not, by itself, define what happens after either button is released: that depends on the contact blocks and the circuit behind them.<\/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=\"Industrial push button controls for a 22mm panel layout\" src=\"https:\/\/onpowbutton.com\/wp-content\/uploads\/2026\/07\/046622c970334de18051b3e2b2208537.webp\" \/><\/figure>\n<p style=\"margin:0 0 16px;line-height:1.7\">For a conventional manual motor-control circuit, a momentary start contact energizes a coil and an auxiliary contact maintains the coil after the operator is released. A stop contact opens the coil path and drops the contactor. <a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/control.com\/technical-articles\/how-to-wire-motor-starters-and-contactors\/\" target=\"_blank\" rel=\"noopener\">Control.com\u2019s motor-starter explanation<\/a> illustrates that control-circuit principle; it is not a wiring diagram for every machine.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">The real question is therefore not \u201cis it a green\/red button?\u201d but \u201cwhich contacts are fitted, what do they operate, and what should occur after loss of control power?\u201d The user question, \u201cdoes it close the contacts when green is pushed and keeps it closed until red is pushed?\u201d, is a useful reminder that the operator action and the electrical latch are separate design decisions.<\/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 requirement<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Verify before selection<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Why it matters<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Command function<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Start, Stop, reset, or another action<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Labels alone do not define circuit logic<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Contact function<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">NO, NC, or a documented combination<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">The circuit needs the intended state at rest<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Control supply<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Coil\/control voltage and circuit type<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">The operator must suit the actual command circuit<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Panel interface<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Hole, thickness, clearance, and rear depth<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">A nominal 22mm description is not a full mechanical drawing<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"margin:0 0 16px;line-height:1.7\">For wider context on the common panel size, see the <a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/onpowbutton.com\/ru\/news\/22mm-push-button-switch-guide\/\">22mm push button switch guide<\/a>.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"part-2-which-start-and-stop-contacts-should-the-circuit-use\">Part 2. Which start and stop contacts should the circuit use?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">In a common three-wire control arrangement, Start is a normally open (NO) contact. Pressing it completes the control path long enough to energize the contactor coil.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Stop is normally closed (NC), so opening it removes coil power. A normally open auxiliary contact on the contactor is then placed in parallel with Start to create the seal-in path.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">That arrangement answers a frequent need, but it is not permission to assume that every dual push button contains one NO and one NC contact. A product order should state the required contact arrangement, number of circuits, and whether the operator must be momentary or maintained.

How should a 22mm start\/stop layout fit the panel?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Panel space is the first mechanical filter. The front face must be readable and reachable, while the rear has to accommodate contact blocks, wiring bends, and any terminals.

This is especially useful on compact control boxes, but spacing, legends, and accidental-operation risk remain system-level decisions. When illumination is part of the requirement, specify the lamp circuit separately; <a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/onpowbutton.com\/ru\/news\/12v-vs-24v-illuminated-push-button-switches\/\">12V vs 24V illuminated push buttons<\/a> explains why the LED supply is not interchangeable by appearance.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">The 22mm hole is an interface, not a performance statement. It does not establish the contact duty, the panel-seal rating, the assembly torque, or the accessory compatibility. Keep the product drawing, panel drawing, and wiring schedule together during review.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"part-4-what-does-the-ip-option-actually-protect\">Part 4.

When should a dual push button control a contactor instead of a load?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Where a machine load needs a purpose-selected power-switching device, use the dual button as a control input to the contactor coil rather than declaring the button a direct-load switch. The contactor and overload arrangement must be selected for the actual load, supply, duty category, protection scheme, and machine design.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">This boundary matters because a button\u2019s thermal or insulation value is not a complete switched-load specification. Arc interruption, inductive load duty, operation frequency, inrush, wiring, short-circuit protection, and enclosure temperature can all change the suitable device choice. The control button remains valuable: it provides the local command; the contactor supplies the power switching in a properly engineered circuit.<\/p>\n<blockquote>\n<p style=\"margin:0 0 16px;line-height:1.7\"><strong>From the field:<\/strong> A user asked whether the green button \u201ckeeps it closed until red is pushed.\u201d That concern is best answered by documenting the auxiliary seal-in circuit, not by assuming a latching dual operator. \u2014 <a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/electronics.stackexchange.com\/questions\/128707\/how-start-stop-push-button-switches-work\" target=\"_blank\" rel=\"noopener\">Electronics Stack Exchange discussion<\/a><\/p>\n<\/blockquote>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"part-6-when-does-the-hby5j-10-fit-the-documented-requirement\">Part 6.

An operator\u2019s front-panel rating does not automatically rate the enclosure, cable entries, or terminals.<\/p>\n<h3 style=\"margin:28px 0 12px\">Can this dual button switch a motor directly?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Do not decide that from colours, size, Ui, or Ith. Use a documented operational switching category and complete circuit design; use a contactor control circuit where the load requires it.<\/p>\n<h3 style=\"margin:28px 0 12px\">What should I send for an HBY5J-10 quotation?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Send the desired contact function, panel details, control voltage, exposure\/IP requirement, illumination need, quantity, and any required documentation.<\/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: Control circuit devices and switching elements<\/a><\/li>\n<li style=\"margin:0 0 8px\"><a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/www.se.com\/au\/en\/faqs\/FA142752\/\" target=\"_blank\" rel=\"noopener\">Schneider Electric: 22mm push-button IP rating FAQ<\/a><\/li>\n<li style=\"margin:0 0 8px\"><a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/www.se.com\/au\/en\/faqs\/FAQ000272037\/\" target=\"_blank\" rel=\"noopener\">Schneider Electric: Push-button conformity and approvals FAQ<\/a><\/li>\n<li style=\"margin:0 0 8px\"><a style=\"color:#27649a;text-decoration:underline\" href=\"https:\/\/control.com\/technical-articles\/how-to-wire-motor-starters-and-contactors\/\" target=\"_blank\" rel=\"noopener\">Control.com: How to Wire Motor Starters and Contactors<\/a><\/li>\n<\/ul>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>A dual push button switch puts two command actions into one panel location; for a typical start\/stop station, the contact functions, control circuit, and front-panel IP requirement must be specified before selecting the operator.
