Expert Answer:

Pls. post each question individually.

The switch is always connected in a live wire, so that when the switch is off no current passes through the appliance. Incase it is connected in the neutral wire , an electric appliance will reamain connected to the live wire even when the switch is off and so if someone happens to touch the appliance , he or she will get a shock which is fatal sometimes.
