简介： A key switch in a household light often has an indicator light. The resistance of the indicator lamp is great, so that the current in the circuit is very small, so that the voltage of the electrical appliances at night can not reach the rated voltage and can not be bright, under normal circumstances, there is a capacitor in the indicator lamp, because the indicator lamp is not capable of 220V voltage.
