一、微動開關工作原理是什么

微(wei)動開關(guan)雖小，但在我們的(de)日常(chang)生(sheng)活中起到不可(ke)替代的(de)作用，在需(xu)頻繁換接電(dian)路的(de)設備(bei)中實(shi)現(xian)自動控制及安全保護。目前，它已廣泛(fan)應(ying)用于電(dian)子設備(bei)、儀器(qi)儀表、礦山、電(dian)力系統、家用電(dian)器(qi)設備(bei)，以(yi)及航(hang)天、航(hang)空(kong)、導彈、坦(tan)克等軍事領域。那么你知道微(wei)動開關(guan)工作原理是什么嗎？

微動(dong)(dong)(dong)(dong)(dong)(dong)(dong)開(kai)(kai)關原(yuan)理：外機械(xie)力通(tong)(tong)過傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)元件(jian)（按銷、按鈕(niu)、杠桿(gan)、滾輪等）將力作(zuo)用于動(dong)(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)簧(huang)(huang)片(pian)上(shang)(shang)，當(dang)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)簧(huang)(huang)片(pian)位移到臨界點(dian)時產生(sheng)瞬(shun)時動(dong)(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)，使(shi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)簧(huang)(huang)片(pian)末端的(de)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)觸(chu)點(dian)與定(ding)觸(chu)點(dian)快(kuai)速接通(tong)(tong)或斷開(kai)(kai)。當(dang)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)元件(jian)上(shang)(shang)的(de)作(zuo)用力移去后(hou)，動(dong)(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)簧(huang)(huang)片(pian)產生(sheng)反向(xiang)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)力，當(dang)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)元件(jian)反向(xiang)行程達到簧(huang)(huang)片(pian)的(de)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)臨界點(dian)后(hou)，瞬(shun)時完成(cheng)反向(xiang)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)。微動(dong)(dong)(dong)(dong)(dong)(dong)(dong)開(kai)(kai)關的(de)觸(chu)點(dian)間(jian)距(ju)小(xiao)、動(dong)(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)行程短、按動(dong)(dong)(dong)(dong)(dong)(dong)(dong)力小(xiao)、通(tong)(tong)斷迅速。其動(dong)(dong)(dong)(dong)(dong)(dong)(dong)觸(chu)點(dian)的(de)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)速度(du)與傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)元件(jian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)速度(du)無關。

二、微動開關型號大全

雖然微動型(xing)開(kai)關(guan)的種類很多，但是(shi)他的結構大多是(shi)相(xiang)同的，它(ta)具有(you)微小間(jian)隔和(he)速動機構，被外(wai)殼覆(fu)蓋，外(wai)部有(you)轉動器，且外(wai)型(xing)較小。然而，微型(xing)開(kai)關(guan)的型(xing)號也有(you)著不(bu)同的類型(xing)，例如WK-01C、WK-01A、WK-01B、WK-04C、KW7-2、KW7-3、KW7-4、KW7-5、KW7-6、KW10-0，KWX-1、KWX-1、KE10-01、DS-448、DS-438、DS-428、V-155-1C25、V-145-1C25、V-135-1C25、RWA-601、RWA-602、RWA-603、RWA-604、RWA-605等。

三、微動開關常開和常閉是什么意思

微(wei)(wei)動(dong)(dong)開關的三(san)個腳分別(bie)叫為共用(yong)端子，常(chang)(chang)開端子，常(chang)(chang)閉端子。用(yong)符號來表示，如下符號：NO為常(chang)(chang)開，NC為常(chang)(chang)閉。簡單(dan)來說，微(wei)(wei)動(dong)(dong)開關常(chang)(chang)閉是(shi)指：不按(an)(an)壓(ya)一(yi)直閉合著導通信號，按(an)(an)壓(ya)下去就會斷(duan)開信號。而(er)微(wei)(wei)動(dong)(dong)開關常(chang)(chang)開是(shi)指：不按(an)(an)壓(ya)是(shi)沒(mei)信號，按(an)(an)壓(ya)下去是(shi)接觸了(le)導通信號。主要是(shi)這(zhe)兩(liang)種狀態執(zhi)行(xing)負載(zai)電路控制的功能(neng)不一(yi)樣而(er)已。兩(liang)腳是(shi)單(dan)功能(neng)、三(san)腳是(shi)常(chang)(chang)閉、常(chang)(chang)開功能(neng)都有(you)，可以進行(xing)轉換(huan)。

四、微動開關接線方法

1、需要分清楚(chu)微動(dong)開(kai)關上(shang)面的不(bu)同(tong)節(jie)點(dian)(dian)，比(bi)如(ru)說有公共點(dian)(dian)，還有一個(ge)是閉合(he)點(dian)(dian)，以(yi)及常開(kai)點(dian)(dian)。區(qu)分開(kai)了之后，就可以(yi)開(kai)始接線。

2、公共點就(jiu)好像插(cha)座(zuo)中的零線(xian)，所以(yi)可以(yi)直接接上地(di)線(xian)上。

3、常(chang)開點(dian)就好比(bi)打(da)開的開關，要(yao)使得電流經(jing)過這(zhe)個點(dian)。

4、閉合(he)點就(jiu)是(shi)斷開電(dian)流(liu)通過的一個節點。

5、把相應的點接(jie)到對(dui)應的位置就(jiu)可以了(le)。
