Capacitive dimmer switch circuit is shown as the chart, it uses the principle of capacitors having AC capacitance. When S is located in the position in the figure, E bulb emits normal light, that is the maximum brightness; when it is switched to the position ②, as the 2μF capacitor is connected in series C1, light intensity of E decreases; when it is switched to the position ③, because of C2
