薄膜開關是(shi)集按鍵(jian)功能、指(zhi)示元件(jian)、儀(yi)器面板(ban)為(wei)一(yi)體的一(yi)個(ge)操(cao)作系統。由(you)面板(ban)、上(shang)(shang)電(dian)(dian)(dian)(dian)路、隔離層、下(xia)電(dian)(dian)(dian)(dian)路四部分組成。為(wei)輕觸(chu)接通式(shi)常開(kai)(kai)開(kai)(kai)關(guan)，正常情況下(xia)薄膜(mo)開(kai)(kai)關(guan)的上(shang)(shang)、下(xia)觸(chu)點(dian)呈斷開(kai)(kai)狀態。按下(xia)薄膜(mo)開(kai)(kai)關(guan)，上(shang)(shang)電(dian)(dian)(dian)(dian)路的觸(chu)點(dian)向下(xia)變形(xing)，與下(xia)電(dian)(dian)(dian)(dian)路的極板(ban)接觸(chu)導通，手指(zhi)松開(kai)(kai)后，上(shang)(shang)電(dian)(dian)(dian)(dian)路觸(chu)點(dian)反(fan)彈回(hui)來，電(dian)(dian)(dian)(dian)路斷開(kai)(kai)，回(hui)路觸(chu)發(fa)一(yi)個(ge)信號。薄膜(mo)開(kai)(kai)關(guan)結構嚴謹，外形(xing)美觀，密(mi)封性好。具有(you)防潮濕，使用(yong)(yong)壽命長等(deng)特點(dian)。廣泛應用(yong)(yong)于電(dian)(dian)(dian)(dian)子通訊、電(dian)(dian)(dian)(dian)子測(ce)量的儀(yi)器，工業控制，醫療設備，汽車工業，智能玩具，家用(yong)(yong)電(dian)(dian)(dian)(dian)器等(deng)領域。
