China Supply LED Indicator Light Indicator Lamp Equipment Indicator Lights

A button switch for home lighting often has an indicator light on it. The resistance of this type of indicator light is extremely high, causing the current in the circuit to be extremely low, resulting in the voltage of the electrical appliance not reaching the rated voltage at night and not being able to light up. Generally, this type of indicator light has a capacitor inside because a small indicator light cannot accommodate a voltage of 220V.
