一、微動開關的作用有哪些

微(wei)動開(kai)關雖(sui)小，但在我們(men)的(de)日常生活(huo)中(zhong)(zhong)起(qi)到不可替代的(de)作用，在需頻繁換接電路的(de)設備(bei)(bei)中(zhong)(zhong)實現自動控(kong)制及安全保護(hu)。目前，它已廣(guang)泛應用于電子(zi)設備(bei)(bei)、儀器儀表、礦(kuang)山、電力系統、家用電器設備(bei)(bei)，以(yi)及航天、航空、導(dao)彈(dan)、坦克等軍(jun)事領域。

另外，它(ta)們還可以(yi)應用在電(dian)腦鼠標、汽車鼠標器、汽車電(dian)子產品、通訊(xun)設(she)備、軍(jun)工(gong)產品，以(yi)及測(ce)試儀器、燃氣熱(re)水器、煤氣灶(zao)、小家(jia)電(dian)、微波爐、電(dian)飯(fan)鍋、浮球設(she)備配(pei)套、醫療器械、樓宇自動化、電(dian)動工(gong)具及一般電(dian)氣和無線(xian)電(dian)設(she)備、24小時(shi)定(ding)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原理是什(shen)么吧！

微動(dong)(dong)(dong)(dong)開(kai)關(guan)原理：外機械力(li)(li)通(tong)(tong)過傳動(dong)(dong)(dong)(dong)元(yuan)件(jian)（按銷(xiao)、按鈕、杠桿、滾輪等(deng)）將力(li)(li)作(zuo)(zuo)用(yong)于動(dong)(dong)(dong)(dong)作(zuo)(zuo)簧(huang)片(pian)上，當(dang)(dang)動(dong)(dong)(dong)(dong)作(zuo)(zuo)簧(huang)片(pian)位移到臨界點(dian)(dian)(dian)時(shi)產生(sheng)瞬時(shi)動(dong)(dong)(dong)(dong)作(zuo)(zuo)，使(shi)動(dong)(dong)(dong)(dong)作(zuo)(zuo)簧(huang)片(pian)末端的(de)動(dong)(dong)(dong)(dong)觸(chu)(chu)點(dian)(dian)(dian)與定觸(chu)(chu)點(dian)(dian)(dian)快速(su)接(jie)通(tong)(tong)或斷開(kai)。當(dang)(dang)傳動(dong)(dong)(dong)(dong)元(yuan)件(jian)上的(de)作(zuo)(zuo)用(yong)力(li)(li)移去后(hou)，動(dong)(dong)(dong)(dong)作(zuo)(zuo)簧(huang)片(pian)產生(sheng)反(fan)向動(dong)(dong)(dong)(dong)作(zuo)(zuo)力(li)(li)，當(dang)(dang)傳動(dong)(dong)(dong)(dong)元(yuan)件(jian)反(fan)向行(xing)程達到簧(huang)片(pian)的(de)動(dong)(dong)(dong)(dong)作(zuo)(zuo)臨界點(dian)(dian)(dian)后(hou)，瞬時(shi)完(wan)成反(fan)向動(dong)(dong)(dong)(dong)作(zuo)(zuo)。微動(dong)(dong)(dong)(dong)開(kai)關(guan)的(de)觸(chu)(chu)點(dian)(dian)(dian)間距小、動(dong)(dong)(dong)(dong)作(zuo)(zuo)行(xing)程短(duan)、按動(dong)(dong)(dong)(dong)力(li)(li)小、通(tong)(tong)斷迅(xun)速(su)。其動(dong)(dong)(dong)(dong)觸(chu)(chu)點(dian)(dian)(dian)的(de)動(dong)(dong)(dong)(dong)作(zuo)(zuo)速(su)度與傳動(dong)(dong)(dong)(dong)元(yuan)件(jian)動(dong)(dong)(dong)(dong)作(zuo)(zuo)速(su)度無關(guan)。
