  A relay is actually an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays a role in automatic regulation, safety protection, and conversion circuits in the circuit.

  The function of a fuse is to: when a circuit malfunctions or is abnormal, the current continuously increases, and the increased current may damage some important or valuable components in the circuit, or burn the circuit or even cause a fire. If the fuse is correctly installed in the circuit, the fuse will fuse and cut off the current when the current abnormally rises to a certain height and time, thereby protecting the safe operation of the circuit.

  The relay can be 'off' or 'on' through current control, that is, it can be reconnected after being disconnected, while the Shenzhen fuse needs to be replaced after being disconnected, and programs cannot be used to reconnect it.
