一、微動開關的作用有哪些

微動開(kai)關雖小(xiao)，但在(zai)我們的(de)日(ri)常生活中起到不可(ke)替代的(de)作用(yong)，在(zai)需頻繁換(huan)接(jie)電(dian)路的(de)設(she)備(bei)中實現自動控(kong)制及安(an)全保護。目前，它已廣泛應用(yong)于(yu)電(dian)子設(she)備(bei)、儀(yi)(yi)器(qi)儀(yi)(yi)表、礦山、電(dian)力系統、家用(yong)電(dian)器(qi)設(she)備(bei)，以(yi)及航天、航空、導彈、坦克(ke)等軍事領域。

另外，它們還可以應用(yong)在(zai)電(dian)腦鼠標(biao)、汽(qi)(qi)車鼠標(biao)器(qi)、汽(qi)(qi)車電(dian)子產(chan)品、通訊設(she)(she)備(bei)、軍(jun)工產(chan)品，以及(ji)測(ce)試(shi)儀器(qi)、燃(ran)氣熱水(shui)器(qi)、煤(mei)氣灶、小家電(dian)、微波爐(lu)、電(dian)飯鍋、浮球設(she)(she)備(bei)配套、醫療(liao)器(qi)械(xie)、樓宇(yu)自動(dong)(dong)化、電(dian)動(dong)(dong)工具及(ji)一般(ban)電(dian)氣和無(wu)線電(dian)設(she)(she)備(bei)、24小時(shi)定時(shi)器(qi)中(zhong)。

二、微動開關工作原理是什么

前文已經簡單了解了微動開關的作用，接著咱們再來看看微動開關工(gong)作原理是(shi)什么吧！

微動(dong)(dong)(dong)開關原(yuan)理：外機(ji)械力通(tong)過(guo)傳(chuan)動(dong)(dong)(dong)元(yuan)(yuan)(yuan)件（按(an)銷(xiao)、按(an)鈕(niu)、杠桿、滾(gun)輪等(deng)）將力作(zuo)(zuo)(zuo)用(yong)于動(dong)(dong)(dong)作(zuo)(zuo)(zuo)簧(huang)片(pian)上，當動(dong)(dong)(dong)作(zuo)(zuo)(zuo)簧(huang)片(pian)位移到臨界點時(shi)產生瞬(shun)時(shi)動(dong)(dong)(dong)作(zuo)(zuo)(zuo)，使動(dong)(dong)(dong)作(zuo)(zuo)(zuo)簧(huang)片(pian)末端(duan)的(de)動(dong)(dong)(dong)觸點與(yu)定(ding)觸點快速(su)(su)接(jie)通(tong)或斷開。當傳(chuan)動(dong)(dong)(dong)元(yuan)(yuan)(yuan)件上的(de)作(zuo)(zuo)(zuo)用(yong)力移去后(hou)，動(dong)(dong)(dong)作(zuo)(zuo)(zuo)簧(huang)片(pian)產生反(fan)向(xiang)動(dong)(dong)(dong)作(zuo)(zuo)(zuo)力，當傳(chuan)動(dong)(dong)(dong)元(yuan)(yuan)(yuan)件反(fan)向(xiang)行程達到簧(huang)片(pian)的(de)動(dong)(dong)(dong)作(zuo)(zuo)(zuo)臨界點后(hou)，瞬(shun)時(shi)完成反(fan)向(xiang)動(dong)(dong)(dong)作(zuo)(zuo)(zuo)。微動(dong)(dong)(dong)開關的(de)觸點間距小、動(dong)(dong)(dong)作(zuo)(zuo)(zuo)行程短、按(an)動(dong)(dong)(dong)力小、通(tong)斷迅(xun)速(su)(su)。其(qi)動(dong)(dong)(dong)觸點的(de)動(dong)(dong)(dong)作(zuo)(zuo)(zuo)速(su)(su)度(du)與(yu)傳(chuan)動(dong)(dong)(dong)元(yuan)(yuan)(yuan)件動(dong)(dong)(dong)作(zuo)(zuo)(zuo)速(su)(su)度(du)無關。
