    Push Button Switches

    按鈕,也稱為按鈕元件,是市面上最常見的電氣開關制之一。按鈕的操作簡單、結構堅固,從日常家用電器、工業機械,到警報系統、遠程控制裝置,你都能看見他們的蹤影。

    RS歐時提供全面的高品質照明和非照明按鈕開關,各種形狀、尺寸、防水功能、金屬物料和顏色可供挑選。無論是全新的工程項目、還是要更新現有設備,你都可以在這選購適合你的按鈕開關。

    按鈕開關的運作原理

    一個按鈕開關有兩個主要組件:按鈕本身和內部開關機構。當按下按鈕時,推桿便會移動,從而接合或脫離內部觸點,做到連接或中斷電路的效果,也就是電器設備的「開」和「關」。

    按鈕的種類

    按鈕開關有多種類型,每種都有獨特的特性和功能。以下是一些最常見的類型:

    • 瞬時按鈕開關

    也稱為彈簧返回按鈕,是需要持續按壓的開關制類型。當按下按鈕時,按鈕便會打開,而按鈕亦需要一直處於被按壓狀態下才會連接到電源。一旦釋放壓力,開關便會彈回並返回其原始的關閉位置。瞬時按鈕開關通常在瞬時位置周圍有括號以幫助識別。例如 (On)-Off-(On), On-(Off)。

    • 自鎖按鈕開關

    也稱為保持或固定按鈕開關,它與瞬時按鈕開關的特點不同,不需要被持續按壓才會連接電源。當按下按鈕時,它便會保持在開啟位置,直到再次按下按鈕才會解除鎖定、返回原始的關閉位置。

    • 照明按鈕開關

    照明按鈕包含光源,通常是 LED,當按下按鈕時會亮起。照明開關常用於光線不足或黑暗環境中,非常適合需要顯示開關狀態的應用。

    按鈕開關的應用

    按鈕開關在各種工業項目和日常生活中被廣泛使用,其中包括:

    • 控制電氣設備
    • 啟動報警
    • 執行控制序列
    • 小型按鈕開關
    • 工業用開關
    • 防水按鈕應用
