開關

電動天窗的開(kai)關(guan)(guan)由操控(kong)開(kai)關(guan)(guan)和限(xian)位(wei)開(kai)關(guan)(guan)組成(cheng)。

（1）操控(kong)開關(guan)操控(kong)開關(guan)首要(yao)包(bao)括滑(hua)動(dong)開關(guan)和斜(xie)(xie)升(sheng)(sheng)開關(guan)。滑(hua)動(dong)開關(guan)有(you)滑(hua)動(dong)翻開、滑(hua)動(dong)封閉和斷開（中心方位(wei)(wei)）3個擋位(wei)(wei)。斜(xie)(xie)升(sheng)(sheng)開關(guan)也(ye)是(shi)有(you)斜(xie)(xie)升(sheng)(sheng)、斜(xie)(xie)降和斷開（中心方位(wei)(wei)）3個擋位(wei)(wei)。經過操作這些(xie)開關(guan)，令天(tian)窗(chuang)驅動(dong)組織的電動(dong)機完成(cheng)正(zheng)反轉，在不同狀態下(xia)正(zheng)常(chang)工作。

（2）限位(wei)(wei)(wei)開(kai)(kai)關(guan)限位(wei)(wei)(wei)開(kai)(kai)關(guan)首要是(shi)用來檢測天窗(chuang)所(suo)在的方位(wei)(wei)(wei)。限位(wei)(wei)(wei)開(kai)(kai)關(guan)靠凸輪轉動(dong)來完成斷開(kai)(kai)和閉(bi)(bi)合。凸輪安裝在驅(qu)動(dong)組織的動(dong)力輸(shu)出(chu)端。當電動(dong)機將動(dong)力輸(shu)出(chu)時，經(jing)過驅(qu)動(dong)齒輪和滑動(dong)螺桿減速以后帶動(dong)凸輪轉動(dong)，于是(shi)凸輪周邊(bian)的凸起部位(wei)(wei)(wei)牽動(dong)開(kai)(kai)關(guan)使其開(kai)(kai)閉(bi)(bi)，以完成對天窗(chuang)的自動(dong)操控。

操控系統

操控系統是一個數字操控電路，并設有定時器、蜂鳴器和繼電器等，其作用是承受開關輸入的信息，經過數字電路進行邏輯運算，確定繼電器的動作，操控天窗開閉。成品電動天窗
