一、微動開關工作原理是什么
微動開關雖小,但在我們的日常生活中起到不可(ke)替(ti)代的作(zuo)用,在需(xu)頻繁換接電(dian)路的設備中實現自動控制及安全保護(hu)。目(mu)前,它已廣泛應用于電(dian)子設備、儀器(qi)儀表、礦山、電(dian)力系統、家用電(dian)器(qi)設備,以及航(hang)天(tian)、航(hang)空、導彈、坦(tan)克等軍(jun)事(shi)領域。那么你知道微動開關工作(zuo)原理是什么嗎?
微動(dong)(dong)(dong)(dong)開關(guan)原理:外機械力通(tong)過傳(chuan)動(dong)(dong)(dong)(dong)元(yuan)件(jian)(jian)(按銷、按鈕、杠桿、滾輪等)將力作(zuo)(zuo)用于動(dong)(dong)(dong)(dong)作(zuo)(zuo)簧片上,當動(dong)(dong)(dong)(dong)作(zuo)(zuo)簧片位移(yi)到(dao)臨界(jie)點(dian)(dian)(dian)時產生瞬時動(dong)(dong)(dong)(dong)作(zuo)(zuo),使動(dong)(dong)(dong)(dong)作(zuo)(zuo)簧片末(mo)端的動(dong)(dong)(dong)(dong)觸點(dian)(dian)(dian)與定(ding)觸點(dian)(dian)(dian)快速(su)接通(tong)或斷開。當傳(chuan)動(dong)(dong)(dong)(dong)元(yuan)件(jian)(jian)上的作(zuo)(zuo)用力移(yi)去后,動(dong)(dong)(dong)(dong)作(zuo)(zuo)簧片產生反(fan)向動(dong)(dong)(dong)(dong)作(zuo)(zuo)力,當傳(chuan)動(dong)(dong)(dong)(dong)元(yuan)件(jian)(jian)反(fan)向行(xing)(xing)程達到(dao)簧片的動(dong)(dong)(dong)(dong)作(zuo)(zuo)臨界(jie)點(dian)(dian)(dian)后,瞬時完成反(fan)向動(dong)(dong)(dong)(dong)作(zuo)(zuo)。微動(dong)(dong)(dong)(dong)開關(guan)的觸點(dian)(dian)(dian)間(jian)距小(xiao)、動(dong)(dong)(dong)(dong)作(zuo)(zuo)行(xing)(xing)程短、按動(dong)(dong)(dong)(dong)力小(xiao)、通(tong)斷迅速(su)。其動(dong)(dong)(dong)(dong)觸點(dian)(dian)(dian)的動(dong)(dong)(dong)(dong)作(zuo)(zuo)速(su)度與傳(chuan)動(dong)(dong)(dong)(dong)元(yuan)件(jian)(jian)動(dong)(dong)(dong)(dong)作(zuo)(zuo)速(su)度無關(guan)。
二、微動開關型號大全
雖然(ran)微動(dong)型(xing)開關的(de)種類(lei)很多,但是他的(de)結(jie)構大多是相同的(de),它具有(you)微小間隔和(he)速動(dong)機構,被外(wai)殼覆蓋,外(wai)部有(you)轉動(dong)器,且外(wai)型(xing)較小。然(ran)而,微型(xing)開關的(de)型(xing)號也有(you)著不同的(de)類(lei)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(deng)。
具體的(de)型號介(jie)紹,可(ke)以(yi)到微動開關十大品牌進行查(cha)看哦。
三、微動開關常開和常閉是什么意思
微(wei)動(dong)開(kai)(kai)(kai)(kai)關的三(san)個腳(jiao)分別叫為(wei)共用端(duan)子,常(chang)開(kai)(kai)(kai)(kai)端(duan)子,常(chang)閉端(duan)子。用符(fu)號來(lai)表(biao)示,如下符(fu)號:NO為(wei)常(chang)開(kai)(kai)(kai)(kai),NC為(wei)常(chang)閉。簡單來(lai)說,微(wei)動(dong)開(kai)(kai)(kai)(kai)關常(chang)閉是(shi)指(zhi)(zhi):不(bu)(bu)按(an)壓一直閉合著導通信號,按(an)壓下去就會(hui)斷開(kai)(kai)(kai)(kai)信號。而(er)(er)微(wei)動(dong)開(kai)(kai)(kai)(kai)關常(chang)開(kai)(kai)(kai)(kai)是(shi)指(zhi)(zhi):不(bu)(bu)按(an)壓是(shi)沒信號,按(an)壓下去是(shi)接觸了導通信號。主(zhu)要是(shi)這(zhe)兩(liang)種狀態(tai)執(zhi)行負載電路控制(zhi)的功能(neng)(neng)不(bu)(bu)一樣而(er)(er)已(yi)。兩(liang)腳(jiao)是(shi)單功能(neng)(neng)、三(san)腳(jiao)是(shi)常(chang)閉、常(chang)開(kai)(kai)(kai)(kai)功能(neng)(neng)都(dou)有,可以進行轉換。
四、微動開關接線方法
1、需要分(fen)清楚微動(dong)開關上面的不同節點,比如說有(you)(you)公共點,還有(you)(you)一(yi)個是閉(bi)合點,以及常開點。區(qu)分(fen)開了之后,就(jiu)可以開始(shi)接線(xian)。
2、公共點就好像(xiang)插座中的零(ling)線,所以可以直接接上(shang)地線上(shang)。
3、常(chang)開點(dian)(dian)就好(hao)比打(da)開的開關,要使得電流(liu)經過這(zhe)個點(dian)(dian)。
4、閉合點就是斷開(kai)電流通過(guo)的一個(ge)節點。
5、把相應的點接(jie)到對應的位置就可以了。
