微動開關的種類繁多，內部結構有成百上千種，按體積分有普通型、小型、超小型;按防護性能分，有防水型、防塵型、防爆型;按分斷形式分，有單聯型、雙聯型、多連型。提起微動開關，很多人并不會感到陌生，但是若真要讓你對它的細節說出個所以然來，并準確地回答出微動開關是什么，還是讓不少人一頭霧水。今天，一起裝修網小編就為大家講講微動開關原理是什么。

微動開關

微(wei)(wei)動(dong)開(kai)關(guan)(guan)(guan)是具(ju)有微(wei)(wei)小接(jie)點(dian)間隔和快動(dong)機構，用規(gui)定的(de)行程和規(gui)定的(de)力進行開(kai)關(guan)(guan)(guan)動(dong)動(dong)作(zuo)的(de)接(jie)點(dian)機構，用外(wai)殼覆(fu)蓋，其外(wai)部(bu)有驅動(dong)桿的(de)一種開(kai)關(guan)(guan)(guan)，因為其開(kai)關(guan)(guan)(guan)的(de)觸點(dian)間距比較小，故名(ming)微(wei)(wei)動(dong)開(kai)關(guan)(guan)(guan)，又叫靈敏開(kai)關(guan)(guan)(guan)。電氣文字符號為：SM。

微動(dong)開關(guan)的(de)(de)種(zhong)類繁(fan)多，內部(bu)結構有(you)成百上千種(zhong)，按(an)體(ti)積(ji)分有(you)普通(tong)(tong)型(xing)(xing)(xing)(xing)(xing)(xing)、小(xiao)(xiao)型(xing)(xing)(xing)(xing)(xing)(xing)、超小(xiao)(xiao)型(xing)(xing)(xing)(xing)(xing)(xing)；按(an)防護性能(neng)分，有(you)防水型(xing)(xing)(xing)(xing)(xing)(xing)、防塵型(xing)(xing)(xing)(xing)(xing)(xing)、防爆型(xing)(xing)(xing)(xing)(xing)(xing)；按(an)分斷(duan)(duan)形式分，有(you)單聯(lian)型(xing)(xing)(xing)(xing)(xing)(xing)、雙聯(lian)型(xing)(xing)(xing)(xing)(xing)(xing)、多連(lian)型(xing)(xing)(xing)(xing)(xing)(xing)。還有(you)一種(zhong)強斷(duan)(duan)開微動(dong)開關(guan)（當開關(guan)的(de)(de)簧(huang)片不起作(zuo)用的(de)(de)時候(hou)，外力(li)也能(neng)使開關(guan)斷(duan)(duan)開）；按(an)分斷(duan)(duan)能(neng)力(li)分，有(you)普通(tong)(tong)型(xing)(xing)(xing)(xing)(xing)(xing)、直(zhi)流型(xing)(xing)(xing)(xing)(xing)(xing)、微電流型(xing)(xing)(xing)(xing)(xing)(xing)、大(da)電流型(xing)(xing)(xing)(xing)(xing)(xing)。

微動(dong)開關一般以無輔助按壓附(fu)件(jian)(jian)為(wei)基本型(xing)式(shi)(shi)，并且(qie)派生出(chu)小(xiao)行(xing)程(cheng)(cheng)式(shi)(shi)、大行(xing)程(cheng)(cheng)式(shi)(shi)。根據需要可加入不(bu)同輔助按壓輔件(jian)(jian)，根據加入的不(bu)同的按壓輔件(jian)(jian)開關可分為(wei)按鈕式(shi)(shi)、簧片滾輪式(shi)(shi)、杠桿滾輪式(shi)(shi)、短動(dong)臂式(shi)(shi)、長動(dong)臂式(shi)(shi)等(deng)各(ge)種形式(shi)(shi)。

微動開關原理

外機械力通過傳動(dong)(dong)元件（按銷、按鈕、杠桿(gan)、滾輪(lun)等）將力作(zuo)用于動(dong)(dong)作(zuo)簧片上，當動(dong)(dong)作(zuo)簧片位移到臨界點(dian)時產生瞬時動(dong)(dong)作(zuo)，使(shi)動(dong)(dong)作(zuo)簧片末端的動(dong)(dong)觸(chu)點(dian)與定觸(chu)點(dian)快速接通或斷開。

當(dang)傳動(dong)(dong)(dong)(dong)元件上的(de)(de)作(zuo)用力(li)(li)移去后(hou)，動(dong)(dong)(dong)(dong)作(zuo)簧(huang)片產(chan)生反(fan)向動(dong)(dong)(dong)(dong)作(zuo)力(li)(li)，當(dang)傳動(dong)(dong)(dong)(dong)元件反(fan)向行程達到簧(huang)片的(de)(de)動(dong)(dong)(dong)(dong)作(zuo)臨界點(dian)(dian)后(hou)，瞬時完成(cheng)反(fan)向動(dong)(dong)(dong)(dong)作(zuo)。微(wei)動(dong)(dong)(dong)(dong)開關的(de)(de)觸(chu)點(dian)(dian)間距(ju)小、動(dong)(dong)(dong)(dong)作(zuo)行程短(duan)、按動(dong)(dong)(dong)(dong)力(li)(li)小、通斷迅速。其動(dong)(dong)(dong)(dong)觸(chu)點(dian)(dian)的(de)(de)動(dong)(dong)(dong)(dong)作(zuo)速度(du)與傳動(dong)(dong)(dong)(dong)元件動(dong)(dong)(dong)(dong)作(zuo)速度(du)無(wu)關。
