一、微動開關的作用有哪些

微動(dong)開關雖小，但在我們的(de)日常生活中起到(dao)不可替代(dai)的(de)作(zuo)用(yong)(yong)，在需頻繁換接電(dian)路的(de)設備(bei)中實現自動(dong)控制及(ji)安全(quan)保護。目前(qian)，它(ta)已(yi)廣泛應用(yong)(yong)于電(dian)子(zi)設備(bei)、儀(yi)器儀(yi)表、礦山、電(dian)力系統、家(jia)用(yong)(yong)電(dian)器設備(bei)，以及(ji)航(hang)(hang)天(tian)、航(hang)(hang)空(kong)、導彈、坦克等軍事(shi)領(ling)域。

另外，它們還可以(yi)應用(yong)在電(dian)(dian)腦鼠標、汽車鼠標器、汽車電(dian)(dian)子產(chan)(chan)品(pin)、通訊(xun)設(she)備、軍(jun)工(gong)產(chan)(chan)品(pin)，以(yi)及測試(shi)儀器、燃氣熱水器、煤氣灶、小家電(dian)(dian)、微(wei)波爐、電(dian)(dian)飯鍋、浮球設(she)備配套、醫(yi)療(liao)器械、樓宇自動化、電(dian)(dian)動工(gong)具及一般(ban)電(dian)(dian)氣和無線電(dian)(dian)設(she)備、24小時定時器中。

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作原理是什么(me)吧(ba)！

微動(dong)(dong)(dong)(dong)(dong)(dong)開(kai)關(guan)原理(li)：外機械力(li)通過傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)元件（按(an)銷、按(an)鈕、杠桿、滾(gun)輪等）將力(li)作(zuo)(zuo)用于動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)簧(huang)(huang)片上(shang)(shang)，當動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)簧(huang)(huang)片位移到臨界點時(shi)產生瞬(shun)時(shi)動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)，使動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)簧(huang)(huang)片末端的動(dong)(dong)(dong)(dong)(dong)(dong)觸點與(yu)定觸點快速接通或斷(duan)開(kai)。當傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)元件上(shang)(shang)的作(zuo)(zuo)用力(li)移去(qu)后，動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)簧(huang)(huang)片產生反向動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)力(li)，當傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)元件反向行程達到簧(huang)(huang)片的動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)臨界點后，瞬(shun)時(shi)完成反向動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)。微動(dong)(dong)(dong)(dong)(dong)(dong)開(kai)關(guan)的觸點間距小、動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)行程短、按(an)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)小、通斷(duan)迅速。其(qi)動(dong)(dong)(dong)(dong)(dong)(dong)觸點的動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)速度(du)與(yu)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)元件動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)速度(du)無關(guan)。
