一、微動開關工作原理是什么
微(wei)動(dong)(dong)開關雖小,但(dan)在我們的(de)日常(chang)生活中起(qi)到不可替代的(de)作(zuo)用(yong)(yong),在需頻繁換接電路的(de)設(she)備中實現自(zi)動(dong)(dong)控(kong)制及安全保護。目前,它(ta)已廣泛應用(yong)(yong)于(yu)電子設(she)備、儀(yi)器儀(yi)表、礦山、電力系(xi)統(tong)、家用(yong)(yong)電器設(she)備,以及航天、航空(kong)、導(dao)彈、坦克等軍事領(ling)域。那么你(ni)知道微(wei)動(dong)(dong)開關工(gong)作(zuo)原理是(shi)什么嗎?
微動(dong)(dong)(dong)(dong)開關原理:外機(ji)械力通(tong)過傳(chuan)(chuan)動(dong)(dong)(dong)(dong)元(yuan)件(jian)(按(an)銷、按(an)鈕、杠桿、滾輪等)將力作(zuo)用于動(dong)(dong)(dong)(dong)作(zuo)簧(huang)片(pian)上(shang)(shang),當(dang)(dang)動(dong)(dong)(dong)(dong)作(zuo)簧(huang)片(pian)位移到(dao)臨界點(dian)(dian)(dian)(dian)時(shi)(shi)產(chan)生瞬時(shi)(shi)動(dong)(dong)(dong)(dong)作(zuo),使動(dong)(dong)(dong)(dong)作(zuo)簧(huang)片(pian)末端的(de)動(dong)(dong)(dong)(dong)觸(chu)點(dian)(dian)(dian)(dian)與定觸(chu)點(dian)(dian)(dian)(dian)快(kuai)速接通(tong)或斷開。當(dang)(dang)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)元(yuan)件(jian)上(shang)(shang)的(de)作(zuo)用力移去后,動(dong)(dong)(dong)(dong)作(zuo)簧(huang)片(pian)產(chan)生反(fan)(fan)向(xiang)動(dong)(dong)(dong)(dong)作(zuo)力,當(dang)(dang)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)元(yuan)件(jian)反(fan)(fan)向(xiang)行程達到(dao)簧(huang)片(pian)的(de)動(dong)(dong)(dong)(dong)作(zuo)臨界點(dian)(dian)(dian)(dian)后,瞬時(shi)(shi)完成反(fan)(fan)向(xiang)動(dong)(dong)(dong)(dong)作(zuo)。微動(dong)(dong)(dong)(dong)開關的(de)觸(chu)點(dian)(dian)(dian)(dian)間距小、動(dong)(dong)(dong)(dong)作(zuo)行程短、按(an)動(dong)(dong)(dong)(dong)力小、通(tong)斷迅速。其動(dong)(dong)(dong)(dong)觸(chu)點(dian)(dian)(dian)(dian)的(de)動(dong)(dong)(dong)(dong)作(zuo)速度與傳(chuan)(chuan)動(dong)(dong)(dong)(dong)元(yuan)件(jian)動(dong)(dong)(dong)(dong)作(zuo)速度無關。
二、微動開關型號大全
雖(sui)然微動型(xing)開關的(de)種類很多,但(dan)是他的(de)結構大多是相同的(de),它具有微小間隔(ge)和速動機構,被(bei)外殼(ke)覆蓋,外部有轉動器(qi),且(qie)外型(xing)較小。然而,微型(xing)開關的(de)型(xing)號也有著不同的(de)類型(xing),例(li)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)動開(kai)關的(de)三個腳分別叫為(wei)共用(yong)端(duan)子,常(chang)(chang)(chang)開(kai)端(duan)子,常(chang)(chang)(chang)閉(bi)(bi)端(duan)子。用(yong)符(fu)號來表示,如(ru)下(xia)符(fu)號:NO為(wei)常(chang)(chang)(chang)開(kai),NC為(wei)常(chang)(chang)(chang)閉(bi)(bi)。簡單來說,微(wei)動開(kai)關常(chang)(chang)(chang)閉(bi)(bi)是指(zhi):不(bu)按(an)壓一直閉(bi)(bi)合著導通(tong)信號,按(an)壓下(xia)去(qu)就會斷開(kai)信號。而微(wei)動開(kai)關常(chang)(chang)(chang)開(kai)是指(zhi):不(bu)按(an)壓是沒信號,按(an)壓下(xia)去(qu)是接觸了導通(tong)信號。主(zhu)要是這兩種狀態執行負(fu)載(zai)電路控(kong)制(zhi)的(de)功(gong)能(neng)不(bu)一樣(yang)而已。兩腳是單功(gong)能(neng)、三腳是常(chang)(chang)(chang)閉(bi)(bi)、常(chang)(chang)(chang)開(kai)功(gong)能(neng)都有(you),可(ke)以進(jin)行轉換。
四、微動開關接線方法
1、需(xu)要分清楚微動開關上(shang)面的不同節點(dian),比如說有公共點(dian),還有一(yi)個(ge)是閉合點(dian),以(yi)(yi)及(ji)常開點(dian)。區(qu)分開了(le)之(zhi)后,就可以(yi)(yi)開始接(jie)線。
2、公共點就好像插座中(zhong)的零線,所(suo)以可以直接接上地線上。
3、常開(kai)點(dian)就好比打開(kai)的開(kai)關,要(yao)使得電流經過這(zhe)個(ge)點(dian)。
4、閉合點(dian)(dian)就是(shi)斷開電流通過的一(yi)個節點(dian)(dian)。
5、把相應的點接到對應的位置就(jiu)可以了。
