NO! Never switch the neutral, just switch the hot. You would be creating a shock hazard. Switching neutral leaves live voltage at the device even when it appears off. Someone touching the hot and grounded would get a shock.

It would work the same way as switching the live, but it's not good practice in the real world. People expect to find switches on the live feed. You might still find negative switching in cars and some other extra low voltage applications.

Switching the neutral side of the load will shut the load off but does not isolate the load from a potential to ground. There will still be a voltage reading on the "hot" and neutral wires of the load to ground which is a serious safety concern. This is why the switch is always installed on the "hot" side of the load.
No, electric switches should be connected to the hot wire in order to control the flow of electricity. The neutral wire provides a return path for the current and does not need to be switched.
You should never switch the neutral wire. The neutral of the appliance should be connected directly to the neutral wire leading to the service panel neutral bar.
The switch is connected to the phase or line wire rather than the neutral wire for safety reasons. By cutting off the phase wire, the switch can effectively control the flow of electricity to the device, whereas cutting off the neutral wire could still leave the device energized and pose a potential shock hazard.
Unless the switch has a light to indicate the switch is turned on, there is no neutral connection to a single pole switch.
the safest position for a switch is on the live wire and not on the neutral wire
The neutral wire doesn't give an electric shock because it is the same potential as ground. That being said if you come in contact with the "hot" wire and the neutral or ground wire, you become the load and will receive a substantial shock.
