Switches and fuses are commonly used in electrical circuits to control the flow of electricity and protect against overloading and short circuits.
A switch is used to manually open or close a circuit, interrupting or allowing the flow of current. Switches can be installed in series with the load (e.g., a light bulb) or in parallel with the load.
A fuse is an electrical safety device that acts as a fail-safe mechanism to protect against overloading or short circuits. A fuse contains a metal wire or filament that melts when too much current flows through it, breaking the circuit and preventing damage to the electrical system or creating a fire hazard.
Typically, fuses are connected in series with the electrical load and are placed as close to the source of power as possible. This allows the fuse to provide protection to both the load and the wiring in the circuit.
In summary, switches and fuses work together in an electrical circuit to provide control and protection. The switch controls the flow of current while the fuse provides protection against overloading and short circuits.
