一、微動開關的作用有哪些

微動開關(guan)雖小，但在我們(men)的日常(chang)生(sheng)活中起到(dao)不(bu)可替(ti)代(dai)的作用，在需頻(pin)繁換接電(dian)路(lu)的設備中實(shi)現自動控制及安全保(bao)護。目前，它已廣泛應用于電(dian)子設備、儀(yi)器儀(yi)表、礦山、電(dian)力系統、家用電(dian)器設備，以及航天、航空、導彈、坦(tan)克等軍事(shi)領(ling)域。

另外，它們還可以應(ying)用在電(dian)(dian)腦鼠標(biao)、汽車鼠標(biao)器(qi)、汽車電(dian)(dian)子(zi)產(chan)品、通訊設(she)備、軍(jun)工產(chan)品，以及(ji)測試儀器(qi)、燃(ran)氣(qi)熱水(shui)器(qi)、煤氣(qi)灶、小(xiao)家電(dian)(dian)、微波爐、電(dian)(dian)飯鍋、浮球設(she)備配(pei)套(tao)、醫療器(qi)械、樓(lou)宇自動化(hua)、電(dian)(dian)動工具及(ji)一般電(dian)(dian)氣(qi)和(he)無線電(dian)(dian)設(she)備、24小(xiao)時定(ding)時器(qi)中(zhong)。

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(gong)作原理是什么吧！

微動(dong)(dong)(dong)開(kai)關原理：外機械力(li)通過傳(chuan)動(dong)(dong)(dong)元(yuan)件（按(an)銷、按(an)鈕、杠桿、滾輪等(deng)）將力(li)作(zuo)(zuo)(zuo)(zuo)用(yong)于(yu)動(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)簧片(pian)上(shang)，當(dang)動(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)簧片(pian)位移(yi)到臨界點(dian)(dian)(dian)時(shi)(shi)產生(sheng)瞬時(shi)(shi)動(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)，使動(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)簧片(pian)末(mo)端的動(dong)(dong)(dong)觸(chu)點(dian)(dian)(dian)與定觸(chu)點(dian)(dian)(dian)快速(su)接通或斷(duan)開(kai)。當(dang)傳(chuan)動(dong)(dong)(dong)元(yuan)件上(shang)的作(zuo)(zuo)(zuo)(zuo)用(yong)力(li)移(yi)去后(hou)，動(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)簧片(pian)產生(sheng)反(fan)向動(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)力(li)，當(dang)傳(chuan)動(dong)(dong)(dong)元(yuan)件反(fan)向行程達到簧片(pian)的動(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)臨界點(dian)(dian)(dian)后(hou)，瞬時(shi)(shi)完成反(fan)向動(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)。微動(dong)(dong)(dong)開(kai)關的觸(chu)點(dian)(dian)(dian)間距小、動(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)行程短(duan)、按(an)動(dong)(dong)(dong)力(li)小、通斷(duan)迅速(su)。其動(dong)(dong)(dong)觸(chu)點(dian)(dian)(dian)的動(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)速(su)度與傳(chuan)動(dong)(dong)(dong)元(yuan)件動(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)速(su)度無(wu)關。
