For mylar, we have the thickness of 0.05mm and 0.075mm (both are with adhesive). And the mylar with the thickness of 0.05mm is the most commonly used. In addition, we can also produce some metal domes with special thickness according to customer requirements. The main parameters of metal domes are as follows:<\/p>\n\n\n\n<p>Lifespan: 4 to 5 million times<\/p>\n\n\n\n<p>Contact Bounce (on) : &lt;.3ms<\/p>\n\n\n\n<p>Contact Bounce (off) : &lt;6ms<\/p>\n\n\n\n<p>Voltage\/Current Maximum: 12 ma @ 24 volts DC, RL<\/p>\n\n\n\n<p>Contact Resistance:&lt;100 ohms<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_The_function_of_metal_dome\"><\/span>2.

In order to make the bottom edge of the metal dome contact smoothly and increase the stroke, as well as overcome the frictional resistance of the bottom edge to the substrate when the dome moves and facilitate scheduling, corresponding support dots are punched on the edges of metal domes of different shapes. . At the same time, the domes are classified according to their external dimensions, operating strength, stroke height, etc. So there are many types of metal domes. Best Technology customizes different metal dome shapes and specifications according to different product application requirements.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><a href=\"https:\/\/www.metal-domes.com\/blog\/wp-content\/uploads\/2024\/03\/Metal-dome-production.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"356\" src=\"https:\/\/www.metal-domes.com\/blog\/wp-content\/uploads\/2024\/03\/Metal-dome-production.jpg\" alt=\"\" class=\"wp-image-1557\" srcset=\"https:\/\/www.metal-domes.com\/blog\/wp-content\/uploads\/2024\/03\/Metal-dome-production.jpg 600w, https:\/\/www.metal-domes.com\/blog\/wp-content\/uploads\/2024\/03\/Metal-dome-production-300x178.jpg 300w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/a><\/figure><\/div>\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"4_Application_of_metal_domes\"><\/span>4.
