产品简介

金属弹片 ( 又称锅仔片或metal dome, snap dome ) , ( 因为其开关像倒扣过来的锅,故俗称 锅仔片, 或' 锅子片' ) , 英文 metal dome , 采用不锈钢制成， 是开关上的一个重要组成部分，借助于金属弹片的的导通性，在使用者和产品之间起到一个优质的开关的作用。同时，利用金属弹片的稳定回弹力（按下后自动复位），其特点超长的寿命，给使用者提供优质的触觉反馈。金属弹片所使用的材料比较薄 ( 通常使用 0.05mm ~ 0.15mm ) 不锈钢钢带（ 钢材牌号通常使用301或者304 ），金属弹片是开关上的一个重要的组成部分。

金属弹片主要应用于薄膜开关、接触开关、PCB板、FPC板，医疗器械等产品中。金属弹片的工作原理：薄膜按键上的金属弹片位于PCB板上的导电部位( 大部分位于线路板上的金手指上方 ），当受到按压时，弹片的中心点下凹，接触到PCB上的线路,从而形成回路，电流通过，整个产品就得以正常工作。

弹片采用进口不锈钢材料，此材料含碳量低(0.08%)，抗氧化度高, 本产品品质优良，性能好。产品通过SGS认证，提供可靠的质量保证，符合欧盟REAH法规和RoHS指令，产品符合环保要求。
