產品簡介

金屬彈片（又稱鍋仔片或metal dome, snap dome），(因為其開關像倒扣過來的鍋,故俗稱 鍋仔片, 或' 鍋子片'），英文 metal dome,采用不銹鋼製成， 是開關上的一個重要組成部分，借助於金屬彈片的的導通性，在使用者和產品之間起到一個優質的開關的作用。同時，利用金屬彈片的穩定回彈力（按下後自動復位），其特點超長的壽命，給使用者提供優質的觸覺反饋。金屬彈片所使用的材料比較薄（通常使用0.05mm~0.15mm）不銹鋼鋼帶（鋼材牌號通常使用301或者304），金屬彈片是開關上的一個重要的組成部分。金屬彈片主要應用於薄膜開關、接觸開關、PCB板、FPC板，醫療器械等產品中。

金屬彈片的工作原理：薄膜按鍵上的金屬彈片位於PCB板上的導電部位(大部分位於線路板上的金手指上方），當受到按壓時，彈片的中心點下凹，接觸到PCB上的線路,從而形成回路，電流通過，整個產品就得以正常工作。

彈片采用進口不銹鋼材料，此材料含碳量低(0.08%)，抗氧化度高, 本產品品質優良，性能好。產品通過SGS認證，提供可靠的質量保證，符合歐盟REAH法規和RoHS指令，產品符合環保要求。
