One pole might carry a control input while another supports a separate interlock or indication condition. Those descriptions cannot be inferred from pole count alone.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Write a one-line function statement for each circuit before comparing push-button configurations. The statement should identify the controlled device or input, the required contact state at rest, the state after actuation, and whether both actions must occur at exactly the same mechanical operation. This record helps designers, panel builders, and suppliers discuss the same requirement.<\/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\">Decision to document<\/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 assume<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Circuit A function<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Defines the first controlled action<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">That it matches circuit B\u2019s voltage or duty<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Circuit B function<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Defines the second controlled action<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">That two poles mean a safety function<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Contact state at rest<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Distinguishes NO, NC, or other required state<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">That all poles use the same state<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Operating action<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">States momentary or maintained need<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">That every product family offers both<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Mechanical relationship<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">States whether one press must act on both<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">That electrically separate means system-compatible<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"margin:0 0 16px;line-height:1.7\">Search discussions often begin with a simpler phrase: \u201cone pushbutton for two separate circuits.\u201d The useful design response is not to provide a generic wiring shortcut; it is to retain the two functions as separate documented requirements while selecting a mechanically linked operator.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"part-2-read-pole-throw-and-contact-state-language-correctly\">Part 2.

Include the circuit reference, the required state before and after press, the signal or controlled element, and the relationship between the two actions. Where the two circuits use different conditions or supplies, the project documentation must explicitly define that design rather than relying on an operator\u2019s appearance.<\/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\">Control record field<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Circuit A example field<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Circuit B example field<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Drawing reference<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Input or control reference<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Separate input or control reference<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Required state<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">State at rest and after press<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">State at rest and after press<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Contact designation<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Selected drawing field<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Selected drawing field<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Terminal identification<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Terminal reference from the selected part<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Terminal reference from the selected part<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Functional relation<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">What the common press must do<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">What the common press must do<\/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:\/\/onpowbutton.com\/fr\/news\/push-button-switch-contact-terminal-configurations\/\">push button switch contact terminal configurations article<\/a> can help a buyer read common terminal vocabulary.

If a press is intended to return when released, that condition should be stated. If the control behaviour relies on retention, reset logic, or another system element, record the requirement without assuming that a family image or a generic term determines the mechanism.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Mounting information also has a defined reference. Keep the panel cutout, thickness, and terminal envelope on the same released drawing as the two-circuit description, so the electrical notes and mechanical interface are reviewed together.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"part-5-review-panel-layout-and-the-fields-that-belong-in-the-quote\">Part 5.
