Working principle<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Rubber dome keyboard: <\/strong>There is a rubber dome inside the key of the rubber dome keyboard. When the key is pressed, the rubber dome deforms, so that the upper and lower circuit contacts contact, thereby forming a circuit path and triggering signal input.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Mechanical keyboard:<\/strong> Each key of the mechanical keyboard has an independent mechanical axis switch. There are springs, metal contacts and other components inside the mechanical axis. When the key is pressed, the spring inside the axis is compressed, the metal contacts contact, and the circuit is turned on; when the key is released, the spring rebounds.<\/li>\n<\/ul>\n\n\n\n<p><strong>2. Hand feel experience:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Rubber dome keyboard: <\/strong>The hand feel is relatively light and soft, the key stroke is short, the pressing force is small, the rebound speed is fast, and the overall hand feel is relatively soft. When used for a long time, the fingers are not easily fatigued.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Mechanical keyboard:<\/strong> The hand feel is rich and varied, and the hand feel of different mechanical axes varies greatly.<\/li>\n<\/ul>\n\n\n\n<p><strong>3. Service life:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Rubber dome keyboard: <\/strong>The rubber dome may age and weaken after long-term use, resulting in changes in the key feel or poor contact. Generally speaking, the service life of the rubber dome keyboard is relatively short, usually around a few million keystrokes.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Mechanical keyboard:<\/strong> The service life of the mechanical axis is long, generally reaching tens of millions of keystrokes, and even some high-quality mechanical axes can reach hundreds of millions of keystrokes. As long as it is used and maintained normally, the mechanical keyboard can be used for a long time.<\/li>\n<\/ul>\n\n\n\n<p><strong>4. Sound characteristics:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Rubber dome keyboard:<\/strong> The key sound is usually relatively small, and the sound emitted when tapping is relatively soft, and no obvious noise is generated, which is suitable for use in a quiet environment.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Mechanical keyboard:<\/strong> The sound is relatively loud, and a certain amount of noise will be generated during use. However, some mechanical keyboards use silent axes or special noise reduction treatments, so the sound is relatively quiet.<\/li>\n<\/ul>\n\n\n\n<p>Although the <a href=\"https:\/\/www.metal-domes.com\/blog\/2024\/10\/29\/what-is-rubber-dome-switch\/\" title=\"\">rubber dome switch<\/a> is small, it is widely used in many fields such as electronic equipment, household appliances, industrial control, etc. due to its small size, light weight, simple operation and low cost.
