輕觸開(kāi)關(guān)又叫按鍵開(kāi)關(guān)，使用時(shí)以滿足操作力的條件向開(kāi)關(guān)操作方向施壓開(kāi)關(guān)功能閉合接通，當(dāng)撤銷壓力時(shí)開(kāi)關(guān)即斷開(kāi)，其內(nèi)部結(jié)構(gòu)是靠金屬?gòu)椘芰ψ兓瘉?lái)實(shí)現(xiàn)通斷的。

輕觸開(kāi)關(guān)由：嵌件、基座、彈片、按鈕、蓋板組成其中防水類輕觸開(kāi)關(guān)在彈片上加一層聚酰亞胺薄膜，輕觸開(kāi)關(guān)有接觸電阻荷小、精確的操作力誤差、規(guī)格多樣化等方面的優(yōu)勢(shì)。
