一、微動開關的作用有哪些

微動開關雖小，但在我們的日常生活(huo)中起(qi)到不可替代的作用(yong)，在需頻(pin)繁(fan)換接電(dian)路的設(she)備(bei)(bei)中實現(xian)自(zi)動控制及安全保護(hu)。目前，它(ta)已廣(guang)泛應用(yong)于電(dian)子設(she)備(bei)(bei)、儀(yi)器(qi)儀(yi)表、礦(kuang)山、電(dian)力(li)系統、家用(yong)電(dian)器(qi)設(she)備(bei)(bei)，以及航天(tian)、航空、導彈、坦克等軍事領域(yu)。

另外，它們還(huan)可(ke)以應用在電(dian)(dian)腦鼠標(biao)、汽車鼠標(biao)器(qi)、汽車電(dian)(dian)子產品、通訊(xun)設(she)(she)(she)備、軍工(gong)產品，以及測試儀(yi)器(qi)、燃氣(qi)熱水器(qi)、煤氣(qi)灶(zao)、小家電(dian)(dian)、微波爐、電(dian)(dian)飯(fan)鍋、浮球設(she)(she)(she)備配(pei)套、醫療器(qi)械(xie)、樓宇自動化(hua)、電(dian)(dian)動工(gong)具及一般電(dian)(dian)氣(qi)和無線電(dian)(dian)設(she)(she)(she)備、24小時定時器(qi)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(gong)作(zuo)原理(li)是(shi)什么吧！

微(wei)(wei)動(dong)(dong)(dong)(dong)開關原理：外機(ji)械力(li)通過傳動(dong)(dong)(dong)(dong)元(yuan)(yuan)件(jian)（按(an)銷、按(an)鈕、杠桿、滾輪(lun)等）將力(li)作(zuo)(zuo)用于動(dong)(dong)(dong)(dong)作(zuo)(zuo)簧(huang)片(pian)(pian)(pian)上，當(dang)動(dong)(dong)(dong)(dong)作(zuo)(zuo)簧(huang)片(pian)(pian)(pian)位移到臨界(jie)點(dian)(dian)時(shi)產(chan)生瞬時(shi)動(dong)(dong)(dong)(dong)作(zuo)(zuo)，使動(dong)(dong)(dong)(dong)作(zuo)(zuo)簧(huang)片(pian)(pian)(pian)末(mo)端的(de)(de)動(dong)(dong)(dong)(dong)觸(chu)點(dian)(dian)與(yu)定觸(chu)點(dian)(dian)快(kuai)速接通或斷(duan)開。當(dang)傳動(dong)(dong)(dong)(dong)元(yuan)(yuan)件(jian)上的(de)(de)作(zuo)(zuo)用力(li)移去后(hou)，動(dong)(dong)(dong)(dong)作(zuo)(zuo)簧(huang)片(pian)(pian)(pian)產(chan)生反向動(dong)(dong)(dong)(dong)作(zuo)(zuo)力(li)，當(dang)傳動(dong)(dong)(dong)(dong)元(yuan)(yuan)件(jian)反向行(xing)(xing)程達(da)到簧(huang)片(pian)(pian)(pian)的(de)(de)動(dong)(dong)(dong)(dong)作(zuo)(zuo)臨界(jie)點(dian)(dian)后(hou)，瞬時(shi)完成反向動(dong)(dong)(dong)(dong)作(zuo)(zuo)。微(wei)(wei)動(dong)(dong)(dong)(dong)開關的(de)(de)觸(chu)點(dian)(dian)間距小(xiao)、動(dong)(dong)(dong)(dong)作(zuo)(zuo)行(xing)(xing)程短、按(an)動(dong)(dong)(dong)(dong)力(li)小(xiao)、通斷(duan)迅速。其動(dong)(dong)(dong)(dong)觸(chu)點(dian)(dian)的(de)(de)動(dong)(dong)(dong)(dong)作(zuo)(zuo)速度(du)(du)與(yu)傳動(dong)(dong)(dong)(dong)元(yuan)(yuan)件(jian)動(dong)(dong)(dong)(dong)作(zuo)(zuo)速度(du)(du)無關。
