They are made from stainless steel or copper alloys, providing durability and consistent feedback. Their compact size, measured at 8.4 mm in diameter, allows them to fit in tight spaces while maintaining excellent mechanical performance.<\/p>\n\n\n\n<p>These domes are often used in keypads, control panels, medical devices, and automotive electronics where reliable tactile response is critical. Unlike ordinary switches, S8.4F-350-N domes do not require extensive mechanical assemblies, which reduces cost and simplifies the design.<\/p>\n\n\n\n<p>What sets these domes apart is their precise actuation force and consistent travel. This ensures every press produces the same tactile sensation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Does_S84F-350-N_Mean\"><\/span><strong>What Does S8.4F-350-N Mean?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Understanding part number S8.4F-350-N is crucial. It contains key information about the metal dome&#8217;s dimensions, structure, and performance.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-blue-color\">S<\/mark>: <\/strong>Refers to the mold number used in production. This ensures consistent shape, precision, and quality across all domes produced in this series.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-blue-color\">8.4<\/mark>:<\/strong> Indicates the dome diameter, 8.4 mm. This dimension is crucial for ensuring compatibility with your switch design.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-blue-color\">F<\/mark>: <\/strong>Indicates the dome type. Typically, \u201cF\u201d represents a four-leg design, which provides stability and even force distribution.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-blue-color\">350<\/mark>:<\/strong> Denotes the actuation force in grams. In this case, 350 grams of force is needed to fully depress the dome, giving a firm and reliable tactile response.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-blue-color\">N<\/mark>: <\/strong>No dimple. The dome surface is smooth without a center dimple, offering uniform contact and a cleaner \u201cclick\u201d experience.<\/li>\n<\/ul>\n\n\n\n<p>By decoding this number, a suitable metal dome can be quickly located. Matching drive force, size, and plating ensure mechanical reliability.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Does_the_Metal_Domes_Diameter_Affect\"><\/span><strong>What Does the Metal Dome&#8217;s Diameter Affect?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The diameter of a metal dome significantly impacts both tactile feel and performance. A larger diameter dome, like the S8.4F-350-N, provides a more stable \u201cclick\u201d and distributes force evenly across the dome\u2019s surface.<\/p>\n\n\n\n<p>Conversely, smaller domes may require less space but can feel less substantial when pressed. They may also be more susceptible to uneven actuation forces, which can lead to inconsistent tactile feedback.<\/p>\n\n\n\n<p>Additionally, the diameter affects the dome\u2019s lifespan. A properly sized dome for the application reduces mechanical stress and wear, extending the product\u2019s operational life. This makes the S8.4F-350-N ideal for devices that see repeated use or require high reliability over thousands of actuation cycles.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><a href=\"https:\/\/www.metal-domes.com\/blog\/wp-content\/uploads\/2025\/11\/S8.4F-350-N-metal-domes-3.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"829\" src=\"https:\/\/www.metal-domes.com\/blog\/wp-content\/uploads\/2025\/11\/S8.4F-350-N-metal-domes-3-1024x829.png\" alt=\"What are S8.4F-350-N Metal Domes?

The four legs anchor the dome to the PCB or membrane layer, preventing side-to-side movement. This structure ensures uniform force distribution across the dome when pressed.<\/p>\n\n\n\n<p><strong>Advantages include:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Consistent tactile response: <\/strong>Each press feels identical.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Enhanced durability:<\/strong> Four legs reduce stress on the dome material.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Reduced misalignment risk: <\/strong>The dome stays in place during assembly and operation, improving reliability.<\/li>\n<\/ul>\n\n\n\n<p>These benefits make four-leg designs preferable for critical applications, including medical devices, automotive controls, and industrial switches.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Are_the_Differences_Between_Metal_Domes_with_Different_Actuation_Forces\"><\/span><strong>What Are the Differences Between Metal Domes with Different Actuation Forces?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Actuation force defines how much pressure is needed to compress the dome fully and register a signal. Metal domes like S8.4F-350-N, which require 350 grams of force, provide a firm tactile response suitable for devices where accidental presses must be minimized.<\/p>\n\n\n\n<p>Lower force domes, such as 180\u2013250 grams, are easier to press but may feel \u201csoft\u201d or less precise. These are ideal for light-touch keypads, handheld devices, or applications where user fatigue is a concern.<\/p>\n\n\n\n<p>Higher force domes, around 400 grams or more, ensure strong feedback and prevent unintended actuation. They are often used in industrial controls or environments where accidental presses could cause errors or safety issues.<\/p>\n\n\n\n<p>Selecting the correct actuation force is essential. Too soft, and the dome feels flimsy; too hard, and user comfort suffers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Are_the_Advantages_of_No-Dimmed_Metal_Domes\"><\/span><strong>What Are the Advantages of No-Dimmed Metal Domes?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The \u201cN\u201d in S8.4F-350-N indicates a no-dimple design, meaning the dome surface is smooth. <strong>This simple feature carries several benefits:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Uniform tactile feedback:<\/strong> Without a center dimple, pressure is evenly distributed across the surface, producing a consistent press every time.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cleaner electrical contact: <\/strong>Smooth surfaces reduce the risk of uneven circuit contact, which enhances switch reliability.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Reduced wear:<\/strong> Dimples can concentrate stress in the center of the dome.
