    Push Button Switches

    按鈕開關是指利用按鈕推動傳動機構、使動觸點與靜觸點接通或斷開並實現電路換接的開關。

    按鈕開關如何運作?

    按鈕開關又稱控制按鈕(簡稱按鈕),是一種手動且一般可以自動復位的低壓電器。按鈕開關通常用於電路中發出啟動或停止指令,以控制電磁起動器、接觸器、繼電器等電器線圈電流的接通和斷開。

    按鈕開關是一種按下即動作,釋放即復位的用來接通和分斷小電流電路的電器。一般用於交直流電壓440V以下,電流小於5A的控制電路中,一般不直接操縱主電路,也可以用於互聯電路中。

    • 在按鈕未按下時,動觸頭與上面的靜觸頭是接通的,這對觸頭稱為常閉觸頭。
    • 在按鈕未按下時,動觸頭與下麵的靜觸頭是斷開的,這對觸頭稱為常開觸頭。
    • 按下按鈕,常閉觸頭斷開,常開觸頭閉合;松開按鈕,在復位彈簧的作用下恢復原來的工作狀態。

    按鈕開關的種類

    推動按鈕開關有多種類型,每種都有其獨特的特性和功能。其中一些最常見的包括:

    瞬時型按鈕開關

    瞬時型按鈕開關,又稱為彈簧返回按鈕,是一種需要持續壓縮的開關類型。這種開關需要用戶按住按鈕才能引發相應操作,放開按鈕後操作立即復位(斷開)。

    鎖定型按鈕開關

    鎖定型按鈕開關,又稱為維持型或保持型按鈕,是一種不需要持續壓縮的開關類型。這種開關帶有常開或常閉觸點,開關保持在設定的觸點狀態,直到再次按下按鈕即可切換狀態。

    帶燈按鈕開關

    帶燈按鈕開關結合了一個光源,通常是LED,當按鈕被按下時會亮起。這種發光開關常用於光線暗淡或黑暗的環境中,且非常適合需要視覺指示開關狀態的應用場合。

    按鈕開關的應用

    按鈕開關在各種不同的應用中很受歡迎,包括計算器、按鈕電話和許多家用電器。您可以在家庭、辦公室和工業應用中找到它們。按鈕開關可以打開和關閉機器,或使設備執行特定操作,例如電子計算器、筆記本電腦或台式機的電源按鈕。在某些情況下,特別是對於商業和工業用途,按鈕開關可以通過機械連桿連接,這意味著按下一個按鈕可以導致另一個按鈕釋放。
