What‘s Christmas light fuse?
When the circuit breaks down or is abnormal, the current rises continuously, and the rising current may damage some important devices or valuable devices in the circuit, and may also burn down the circuit or even cause a fire. If the fuse is correctly placed in the circuit, the fuse will blow out and cut off the current when the current rises abnormally to a certain height, thus playing a role in protecting the safe operation of the circuit.
