The invention provides a switch intelligent control plug. The switch intelligent control plug comprises a plugging pin, a concave table, a circular circuit board, an arc-shaped metal dome, a key cover and a fixing ring. A first metal electrode, a second metal electrode, a third metal electrode and a fourth metal electrode are arranged on the surface of the plugging pin and are insulated from one another. The concave table and the fourth metal electrode are connected turning parts. A first conductive electrode and second conductive electrodes are arranged on the circular circuit board, an electrically-connected circuit element is arranged between the first conductive electrode and the second conductive electrode, the first conductive electrode is connected with the third metal electrode, and the second conductive electrode is connected with the fourth metal electrode. When the metal dome is pressed down, the first conductive electrode and the second conductive electrode can be connected. The key cover is arran
