你知道自鎖開關的定義是什么嗎?

       自鎖開關是常用按鈕開關之一。 當開關按鈕第1次準時時,開關導通且維持,為自鎖狀態,當開關按鈕第2次準時時開關斷開而開關按鈕彈出。

      自鎖開關通常指在開關中自帶機械鎖定功能的開關,按壓、松開時按鈕不完全跳閘,在鎖閘狀態下,需再次按壓才能開鎖完全跳閘。 這就是所謂的自鎖開關。 較早直接全部停電電視機,顯示器都是采用這類開關。

      帶燈自鎖開關和普通自鎖開關區別僅是:帶燈開關是充分利用它按鍵內的空間放置一個小指示燈泡或者LED,一端連接零線,另端通常由一個降壓電阻并聯在開關常開觸點上,開關關斷后裝置工作同時給指示燈供電。 它的類型有對角式一次切換、平行式一次切換、跨越式一次切換等。
