一、微動開關的作用有哪些

微動開(kai)關雖小，但在我們(men)的日常生活(huo)中起到不可(ke)替代(dai)的作用(yong)(yong)，在需(xu)頻繁換接電(dian)(dian)(dian)路的設備(bei)中實現自動控制及安全保護。目(mu)前，它已廣泛應用(yong)(yong)于電(dian)(dian)(dian)子設備(bei)、儀(yi)器儀(yi)表、礦山、電(dian)(dian)(dian)力(li)系(xi)統、家用(yong)(yong)電(dian)(dian)(dian)器設備(bei)，以(yi)及航天、航空(kong)、導(dao)彈(dan)、坦克等軍事領域。

另外，它們還(huan)可以應用(yong)在電(dian)(dian)腦(nao)鼠(shu)標(biao)、汽(qi)車鼠(shu)標(biao)器、汽(qi)車電(dian)(dian)子(zi)產品、通訊(xun)設備、軍工(gong)產品，以及測試(shi)儀(yi)器、燃氣(qi)熱(re)水器、煤(mei)氣(qi)灶、小家電(dian)(dian)、微波爐、電(dian)(dian)飯鍋、浮球設備配套、醫療器械、樓宇自動化、電(dian)(dian)動工(gong)具及一(yi)般電(dian)(dian)氣(qi)和無(wu)線(xian)電(dian)(dian)設備、24小時(shi)定時(shi)器中。

二、微動開關工作原理是什么

前文已經簡單了解了微動開關的作用，接著咱們再來看看微動開關工作(zuo)原理是什么(me)吧！

微動(dong)(dong)(dong)(dong)(dong)(dong)開關原(yuan)理：外機械力(li)通(tong)過傳動(dong)(dong)(dong)(dong)(dong)(dong)元(yuan)(yuan)件（按銷(xiao)、按鈕、杠桿、滾輪等）將力(li)作(zuo)(zuo)用(yong)于動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)簧(huang)(huang)片(pian)上，當動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)簧(huang)(huang)片(pian)位移到(dao)臨(lin)界點(dian)(dian)時(shi)產生(sheng)瞬時(shi)動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)，使動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)簧(huang)(huang)片(pian)末端的動(dong)(dong)(dong)(dong)(dong)(dong)觸(chu)點(dian)(dian)與定觸(chu)點(dian)(dian)快速(su)(su)接通(tong)或斷(duan)開。當傳動(dong)(dong)(dong)(dong)(dong)(dong)元(yuan)(yuan)件上的作(zuo)(zuo)用(yong)力(li)移去后，動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)簧(huang)(huang)片(pian)產生(sheng)反向動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)力(li)，當傳動(dong)(dong)(dong)(dong)(dong)(dong)元(yuan)(yuan)件反向行程達到(dao)簧(huang)(huang)片(pian)的動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)臨(lin)界點(dian)(dian)后，瞬時(shi)完成反向動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)。微動(dong)(dong)(dong)(dong)(dong)(dong)開關的觸(chu)點(dian)(dian)間距(ju)小、動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)行程短、按動(dong)(dong)(dong)(dong)(dong)(dong)力(li)小、通(tong)斷(duan)迅速(su)(su)。其(qi)動(dong)(dong)(dong)(dong)(dong)(dong)觸(chu)點(dian)(dian)的動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)速(su)(su)度與傳動(dong)(dong)(dong)(dong)(dong)(dong)元(yuan)(yuan)件動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)速(su)(su)度無關。
