Question

Why is a switch for any appliance always connected to the live wire?

✓

Answer

A switch must be connected to the live wire so that when it is in $\text{OFF}$ position, then the appliance to which it is connected will be disconnected from the live wire. If the switch would be connected to the neutral wire, then the electrical appliance will be connected to the live wire even when the switch is in $\text{OFF}$ position. This may cause an electric shock if a person touches the appliance.
