What is a micro switch with cord?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">A corded micro switch arrives with leads already attached to the switch terminals or potted exit. The OEM routes those leads to a connector, terminal block, or control board. The goal is faster assembly and fewer field wiring mistakes\u2014not an automatic environmental rating.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Define the function of the cord before selecting a series. Ask whether the leads carry signal current or a power load, whether color coding must match the schematic, and whether the exit must clear a bracket or gasket. The cord is part of the component, so cutting or re-terminating it can change both electrical and mechanical behavior.<\/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\">Campo de RFQ<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Por qu\u00e9 importa<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Typical mistake<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Lead length and tolerance<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Routing and connector placement<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Ordering the shortest length, then bending sharply<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Wire gauge and insulation<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Must match load and temperature<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Copying a catalog AWG without load review<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Exit direction<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Clearance to walls and grommets<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Choosing bottom exit when side routing is required<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Connector or bare ends<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Factory crimp versus customer termination<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Adding a connector without revalidation<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"margin:0 0 16px;line-height:1.7\">Utiliza el <a style=\"color:#f27c00;text-decoration:underline\" href=\"https:\/\/lemaele.com\/es\/micro-switch\/\">LEMA Micro Switch product line<\/a> as the category starting point, then confirm cord details on the quotation.<\/p>\n<h2 style=\"margin:42px 0 14px\" id=\"part-2-how-does-it-differ-from-an-ip67-sealed-cable-switch\">Part 2. How does it differ from an IP67 sealed cable switch?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">An IP67 sealed cable switch is validated as a dust-tight assembly with defined temporary immersion performance for the factory lead joint. A general micro switch with cord may only provide factory leads for assembly convenience in a dry or lightly protected cabinet. The words \u201cwith cable\u201d and \u201cwith cord\u201d are often mixed in search results, so the RFQ must state the environmental target.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">If washdown, outdoor splash, or temporary immersion is required, follow the separate <a style=\"color:#f27c00;text-decoration:underline\" href=\"https:\/\/lemaele.com\/es\/blog\/ip67-micro-switch-with-cable-selection-guide\/\">IP67 cable harness selection<\/a> method. Do not assume that any corded part inherits an IP code.<\/p>\n<ul style=\"margin:0 0 18px 1.2em;line-height:1.7\">\n<li style=\"margin:0 0 8px\"><strong>Corded convenience:<\/strong> reduces terminal soldering and wiring errors.<\/li>\n<li style=\"margin:0 0 8px\"><strong>Sealed cable assembly:<\/strong> preserves a defined ingress rating at the factory joint.<\/li>\n<li style=\"margin:0 0 8px\"><strong>Field-wired terminals:<\/strong> keep sealing responsibility with the enclosure design.<\/li>\n<\/ul>\n<h2 style=\"margin:42px 0 14px\" id=\"part-3-which-electrical-fields-define-the-cord\">Part 3. Which electrical fields define the cord?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Wire gauge follows the contact and load class, not the presence of a cord. Logic-level inputs may use lighter conductors; power-duty contacts need insulation and gauge that match voltage, current, and temperature. Confirm inrush if the switch drives a relay coil or lamp.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Also define conductor colors and functions. High-volume lines often rely on color coding to reduce NO\/NC wiring mistakes. Do not assume a supplier\u2019s default colors match your schematic.<\/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\">Load class<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Cord consideration<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Design note<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Logic \/ signal<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Lower current; flexible routing<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Verify controller input conditions<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Resistive AC loads<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Match supplier ampere\/voltage table<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Confirm temperature rise at rated load<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Inductive loads<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">May need heavier insulation or upstream mitigation<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Do not upsize the switch without approval<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"margin:0 0 16px;line-height:1.7\">For baseline family context before cord options, see the <a style=\"color:#f27c00;text-decoration:underline\" href=\"https:\/\/lemaele.com\/es\/blog\/kw7-micro-switch-the-complete-guide-to-specifications-applications\/\">KW7 family specifications<\/a> article, then request the corded SKU details separately.<\/p>\n<h2 style=\"margin:42px 0 14px\" id=\"part-4-how-should-length-and-exit-be-chosen\">Part 4.

Include connector placement, service loop, grommet location, and minimum bend radius. Bottom exit can save height; side exit helps when the switch sits against a wall. Straight exit may suit a harness that leaves immediately toward a board.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Order length with tolerance, not a single \u201cabout\u201d value. Too short forces sharp bends at the exit. Too long creates loops that snag during assembly or vibration testing.

What strain-relief and assembly checks matter?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">A corded switch fails early when the harness pulls on the exit. Add a tie point, clamp, or grommet so motion and vibration do not transfer into the lead joint. After service access, re-check that the cord was not pulled sideways against a sharp edge.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Validate the assembly with production brackets and connectors. Cycle the mechanism while watching contact behavior and inspecting the lead exit for abrasion.
