輕(qing)觸(chu)按(an)鍵(jian)開關(guan) 自鎖(suo)開關(guan)與(yu)撥動開關(guan)有何(he)區(qu)別(bie)
輕觸(chu)按(an)鍵(jian)開關(guan)有單(dan)鍵(jian)式(shi)和多鍵(jian)組(zu)合式(shi)兩種(zhong)類型。單鍵(jian)式(shi)按(an)鍵(jian)開關(guan)壹(yi)般(ban)用(yong)於電(dian)視(shi)機(ji)中作(zuo)電(dian)源(yuan)開關(guan)，它又分(fen)為(wei)自鎖自復位(wei)式(shi)（這(zhe)種(zhong)開關(guan)按(an)壹(yi)下(xia)即接通自(zi)鎖，再(zai)按(an)壹(yi)下(xia)則斷(duan)開復位(wei)）和(he)無鎖式(shi)（不能(neng)鎖定，按(an)動(dong)時(shi)接通，松(song)手(shou)後(hou)復位(wei)）兩種(zhong)結(jie)構(gou)。
多鍵(jian)組(zu)合式(shi)按(an)鍵(jian)開關(guan)分(fen)為(wei)自鎖、互鎖(suo)和(he)無(wu)鎖等(deng)結(jie)構(gou)類型。八(ba)鍵(jian)式(shi)或十(shi)二(er)鍵(jian)開關(guan)早期用(yong)於電(dian)視(shi)機(ji)中作(zuo)節目預選開關(guan)，四(si)鍵(jian)式(shi)按(an)鍵(jian)開關(guan)早期於波輪式(shi)洗衣(yi)機中(zhong)作(zuo)洗滌狀態(tai)選擇開關(guan)。
同是開關(guan)，撥動開關(guan)是通過撥動開關(guan)柄來帶動(dong)滑(hua)塊(kuai)或滑(hua)片的滑(hua)動(dong)，從而(er)控(kong)制(zhi)開關(guan)觸的接通與(yu)斷開。撥動開關(guan)分(fen)為(wei)單極(ji)雙位(wei)和(he)雙極(ji)雙位(wei)兩種(zhong)結(jie)構(gou)形式(shi)，主(zhu)要(yao)用(yong)於電(dian)源(yuan)電(dian)路(lu)的控(kong)制(zhi)及(ji)工作(zuo)狀態電(dian)路(lu)的切換(huan)。而(er)按(an)鍵(jian)開關(guan)壹(yi)般(ban)由(you)手(shou)柄、滑(hua)板(ban)、活(huo)動觸(chu)片、固定端(duan)子、壓簧、外(wai)殼(ke)等構(gou)成，它(ta)是通過按(an)動(dong)開關(guan)手(shou)柄來控(kong)制(zhi)活(huo)動(dong)觸點與(yu)固定端(duan)子觸(chu)點的接通與(yu)關斷(duan)
