A rewirable switch fuse unit is a device that combines a fuse, a switch, and a rewireable connector in one unit. It is used for the protection of electrical circuits and also for the control of the electrical current flow. The switch allows the user to switch the circuit on and off, and the fuse prevents the circuit from overloading. The rewireable connector allows for the easy replacement of the fuse without having to replace the entire unit. Rewirable switch fuse units are commonly used in domestic and industrial applications.
