    按鈕開關

    按鈕開關是指利用按鈕推動傳動機構,使動觸點與靜觸點按通或斷開并實現電路換接的開關。按鈕開關是一種結構簡單,應用十分廣泛的主令電器。在電氣自動控制電路中,用于手動發出控制信號以控制接觸器、繼電器、電磁起動器等。


    電動葫蘆

    電動葫蘆是一種特種起重設備,安裝在天車、龍門吊之上,電動葫蘆具有體積小,自重輕,操作簡單,使用方便等特點,用于工礦企業,倉儲,碼頭等場所。 電動葫蘆結構緊湊,電機軸線垂直于卷筒軸線的電動葫蘆采用蝸輪傳動裝置。其缺點為:長度尺寸大,寬度方面尺寸大,結構粗笨,機械效率低,加工較難等。液壓系統為雙重控制,溢流調節閥、磁接點壓力表均可對壓力進行精確的控制。電器控制部門采用了低電壓控制,增加了支配系統的安全性。
