一、微動開關的作用有哪些

微動開(kai)關雖小(xiao)，但在我們的日常生(sheng)活中起到不可(ke)替代的作用，在需頻繁換接電(dian)路的設備(bei)中實現(xian)自動控制及安全保護。目前，它已廣泛應用于電(dian)子設備(bei)、儀(yi)(yi)器儀(yi)(yi)表、礦山(shan)、電(dian)力系統、家用電(dian)器設備(bei)，以及航天、航空、導彈、坦克等軍(jun)事(shi)領域。

另(ling)外，它們還可以應用在電(dian)(dian)(dian)腦(nao)鼠(shu)標(biao)、汽(qi)車(che)鼠(shu)標(biao)器、汽(qi)車(che)電(dian)(dian)(dian)子產品、通(tong)訊設(she)(she)備(bei)、軍工(gong)產品，以及測試儀器、燃氣熱(re)水器、煤氣灶、小(xiao)(xiao)家電(dian)(dian)(dian)、微(wei)波(bo)爐、電(dian)(dian)(dian)飯鍋、浮球設(she)(she)備(bei)配套、醫(yi)療(liao)器械、樓宇自動化、電(dian)(dian)(dian)動工(gong)具及一般電(dian)(dian)(dian)氣和無(wu)線電(dian)(dian)(dian)設(she)(she)備(bei)、24小(xiao)(xiao)時(shi)定時(shi)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(zuo)原理是(shi)什么吧！

微動(dong)(dong)開(kai)關原理：外(wai)機械(xie)力通(tong)過傳動(dong)(dong)元(yuan)件(jian)（按(an)銷(xiao)、按(an)鈕(niu)、杠桿、滾輪等）將力作(zuo)用于動(dong)(dong)作(zuo)簧(huang)(huang)(huang)片上(shang)，當(dang)動(dong)(dong)作(zuo)簧(huang)(huang)(huang)片位移到臨界(jie)點(dian)(dian)時(shi)產生(sheng)瞬時(shi)動(dong)(dong)作(zuo)，使動(dong)(dong)作(zuo)簧(huang)(huang)(huang)片末端的(de)(de)(de)動(dong)(dong)觸(chu)點(dian)(dian)與定觸(chu)點(dian)(dian)快速(su)(su)(su)(su)接(jie)通(tong)或(huo)斷開(kai)。當(dang)傳動(dong)(dong)元(yuan)件(jian)上(shang)的(de)(de)(de)作(zuo)用力移去后，動(dong)(dong)作(zuo)簧(huang)(huang)(huang)片產生(sheng)反(fan)(fan)向動(dong)(dong)作(zuo)力，當(dang)傳動(dong)(dong)元(yuan)件(jian)反(fan)(fan)向行程達到簧(huang)(huang)(huang)片的(de)(de)(de)動(dong)(dong)作(zuo)臨界(jie)點(dian)(dian)后，瞬時(shi)完成反(fan)(fan)向動(dong)(dong)作(zuo)。微動(dong)(dong)開(kai)關的(de)(de)(de)觸(chu)點(dian)(dian)間(jian)距小、動(dong)(dong)作(zuo)行程短、按(an)動(dong)(dong)力小、通(tong)斷迅速(su)(su)(su)(su)。其(qi)動(dong)(dong)觸(chu)點(dian)(dian)的(de)(de)(de)動(dong)(dong)作(zuo)速(su)(su)(su)(su)度(du)與傳動(dong)(dong)元(yuan)件(jian)動(dong)(dong)作(zuo)速(su)(su)(su)(su)度(du)無關。
