一、微動開關工作原理是什么

微動(dong)開關雖小(xiao)，但在我們的(de)(de)日常生(sheng)活中起到不可替(ti)代的(de)(de)作用，在需頻(pin)繁換接電路的(de)(de)設(she)(she)備(bei)中實現自(zi)動(dong)控(kong)制及安全保護。目前，它已廣泛應(ying)用于電子(zi)設(she)(she)備(bei)、儀(yi)器(qi)儀(yi)表、礦山、電力(li)系統、家(jia)用電器(qi)設(she)(she)備(bei)，以及航(hang)(hang)天、航(hang)(hang)空(kong)、導(dao)彈、坦克(ke)等(deng)軍(jun)事領域(yu)。那(nei)么你知道微動(dong)開關工作原理(li)是什么嗎？

微(wei)動(dong)(dong)(dong)(dong)(dong)(dong)開(kai)關原理：外機械力(li)(li)(li)通過傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)元件（按(an)銷、按(an)鈕、杠桿、滾輪等）將力(li)(li)(li)作(zuo)用(yong)于(yu)動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)簧(huang)片(pian)上(shang)，當動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)簧(huang)片(pian)位移到(dao)臨界(jie)點(dian)時產(chan)生瞬(shun)時動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)，使動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)簧(huang)片(pian)末(mo)端的(de)(de)動(dong)(dong)(dong)(dong)(dong)(dong)觸點(dian)與定觸點(dian)快速(su)接通或斷(duan)開(kai)。當傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)元件上(shang)的(de)(de)作(zuo)用(yong)力(li)(li)(li)移去后，動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)簧(huang)片(pian)產(chan)生反(fan)向(xiang)動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)力(li)(li)(li)，當傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)元件反(fan)向(xiang)行程(cheng)達(da)到(dao)簧(huang)片(pian)的(de)(de)動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)臨界(jie)點(dian)后，瞬(shun)時完成反(fan)向(xiang)動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)。微(wei)動(dong)(dong)(dong)(dong)(dong)(dong)開(kai)關的(de)(de)觸點(dian)間距(ju)小、動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)行程(cheng)短、按(an)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)(li)(li)小、通斷(duan)迅速(su)。其動(dong)(dong)(dong)(dong)(dong)(dong)觸點(dian)的(de)(de)動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)速(su)度(du)與傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)元件動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)速(su)度(du)無關。

二、微動開關型號大全

雖然微(wei)動型(xing)開關(guan)的(de)種(zhong)類很多，但是他的(de)結(jie)構大多是相同(tong)的(de)，它具有(you)微(wei)小(xiao)間隔和速(su)動機構，被外殼覆蓋，外部(bu)有(you)轉動器(qi)，且外型(xing)較小(xiao)。然而(er)，微(wei)型(xing)開關(guan)的(de)型(xing)號也(ye)有(you)著不同(tong)的(de)類型(xing)，例如(ru)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

微動開(kai)(kai)(kai)關的三個腳(jiao)(jiao)分別叫為(wei)(wei)共用端子，常(chang)(chang)(chang)(chang)開(kai)(kai)(kai)端子，常(chang)(chang)(chang)(chang)閉(bi)(bi)端子。用符號(hao)來表示，如下(xia)符號(hao)：NO為(wei)(wei)常(chang)(chang)(chang)(chang)開(kai)(kai)(kai)，NC為(wei)(wei)常(chang)(chang)(chang)(chang)閉(bi)(bi)。簡單來說，微動開(kai)(kai)(kai)關常(chang)(chang)(chang)(chang)閉(bi)(bi)是(shi)指：不(bu)按壓(ya)(ya)一(yi)直(zhi)閉(bi)(bi)合著導通信(xin)號(hao)，按壓(ya)(ya)下(xia)去(qu)就會斷(duan)開(kai)(kai)(kai)信(xin)號(hao)。而微動開(kai)(kai)(kai)關常(chang)(chang)(chang)(chang)開(kai)(kai)(kai)是(shi)指：不(bu)按壓(ya)(ya)是(shi)沒信(xin)號(hao)，按壓(ya)(ya)下(xia)去(qu)是(shi)接觸了(le)導通信(xin)號(hao)。主要是(shi)這兩種狀(zhuang)態(tai)執(zhi)行(xing)負載電路(lu)控制的功(gong)能不(bu)一(yi)樣而已。兩腳(jiao)(jiao)是(shi)單功(gong)能、三腳(jiao)(jiao)是(shi)常(chang)(chang)(chang)(chang)閉(bi)(bi)、常(chang)(chang)(chang)(chang)開(kai)(kai)(kai)功(gong)能都有(you)，可(ke)以進行(xing)轉(zhuan)換。

四、微動開關接線方法

1、需要分清楚微動(dong)開關上面(mian)的不同節點(dian)，比如說有公共(gong)點(dian)，還有一個是閉合點(dian)，以(yi)及常開點(dian)。區分開了(le)之后，就(jiu)可以(yi)開始接線。

2、公(gong)共點(dian)就好像插座中的零線，所以(yi)可以(yi)直接接上地線上。

3、常開點就(jiu)好比打開的(de)開關，要使(shi)得電流經過這個點。

4、閉合(he)點(dian)就是斷開電流通過的一個節點(dian)。

5、把相應的(de)點接到對應的(de)位置(zhi)就可以了。
