兩燈兩鈕防爆操作柱價格（IIB，IIC）
防爆操作柱與防爆控制箱，防爆控制按鈕的區別與
防爆控制按鈕，防爆操作柱，防爆控制箱三者差不多，他們之間有個遞進的關系。
防爆控制按鈕只有少數幾個型號規格，一般只有一鈕，兩鈕，三鈕或者兩鈕一燈這樣子，一般是掛式，價格便宜。如果在防爆控制按鈕的基礎上還要裝電流表，轉換開關，那就叫做防爆操作柱了，防爆操作柱有立式的和掛式的兩種安裝方式，小巧方便，便宜實用。如果裝多個按鈕，多個信號燈，多個電流表、電壓表或其它儀表，多個轉換開關，或多個組合，即多回路組合就要做成防爆控制箱，規格體積較防爆控制按鈕和防爆操作柱都要大，才稱之為控制箱。防爆控制箱一般是掛式的，也可做成立式的。
關于它們的一些別名：防爆按鈕盒，防爆操作箱，防爆機旁箱，防爆機旁操作箱，防爆機旁控制箱，防爆按鈕，防爆控制按鈕盒
防爆防腐操作柱與防爆防腐控制箱，防爆防腐按鈕之間的關系也是這樣的。
