Answer:
Fuse is used as a circuit breaker when the current passed through the wire exceeds the limit of the circuit and hence, it prevents short circuits and fires.
It burns off when very large amount of current is passed through it.
Switch is a device used for breaking or joining a circuit. When in on position, the current begins to flow in the circuit as the circuit becomes closed. But when turned off, current stops flowing as circuit is broken. Circuits are used for stopping the flow of current when not required.
Hope it helps......
(i) Main Switch.: A main switch is a central cut-off switch that controls the smaller cut-off switches and machines of a building (ii)Main Fuse:fuse is a type of low resistance resistor that acts as a sacirificial device to provide over current protection.
