Hots are dedicated to a specific circuit. Neutrals can be shared by other circuits. All the current in a circuit must travel through the hot. This is not always the case with the neutral. The purpose of a switch is to stop the potential voltage from being applied to the load. With the switch on the neutral side of the load this condition is not fulfilled. By shutting the load off with a neutral switch you could not work safely on the load as the potential to ground will still be there and create a shock hazard. <><><> As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

In electrical circuits, a switch is always connected to the line wire to control the flow of electricity to a device. By interrupting the line wire, the switch can effectively turn the power on or off while ensuring that the load remains safe when the switch is off. Connecting the switch to the line wire also helps prevent electrical shock hazards, as the load is de-energized when the switch is in the off position. This configuration maintains proper circuit functionality and safety.
First of all, the correct term is 'line' and not'phase' wire. The reason a switch is always placed in the line conductor, rather than in the neutral conductor, is that its function is not simply to break the circuit, but also to ensure that the circuit's load is disconnected from the line potential. If the switch were to be placed in the neutral conductor, it would still break the circuit, but the load will still be at line potential and present a shock hazard to anyone attempting to work on the load (e.g. to remove a lamp from its holder).
A switch in circuit symbols is represented by a break in the line with a gap or by a line that can be closed to complete the circuit. It typically looks like a gap that can be closed or opened to control the flow of electrical current in a circuit.
The switch should always be on the HOT side. This way, when the switch is OFF, the light fixture is SAFE. Otherwise, you would have a HOT fixture with no clear return path when the swith is OFF -- very dangerous.
A high voltage pole top switch has joined linkage from the top cross-arm switch to a D handle at ground level. This switch is kept in a padlocked state when open or closed. When the switch needs to be opened by linemen it is unlocked and the D handle is moved to the down position and re locked. This is so that the switch does not get inadvertently closed, and the line becomes re energised, while workmen are still on the circuit.

Your question is rather vague but, for a.c. systems, a switch must always be placed in the line conductor, neverthe neutral conductor.
A Switch on a domestic supply has always got to be on the LIVE part of that circuit. A double pole switch switches both the LIVE and NEUTRAL off together.
In electrical diagrams, a line and a circle typically represent a switch. If the line is connected through the circle, the switch is in the "on" position, allowing current to flow. Conversely, if the line is disconnected from the circle, the switch is "off," interrupting the current flow. This visual representation helps quickly identify the status of the switch in a circuit.
If a switch was on the neutral wire the live wire would still be at the mains potential even when the switch was off. This would cause on en electric shock when one handles any conductor linked to the live wire
in electrical its usually uses I1 and I2 .....i3 etc they actually stands for intensity (ampere).you might have notices these must be always in series in a line

The maximum amount of electrical current that can flow through a single line and load on a switch is determined by the ampere rating of the switch. This rating indicates the maximum safe current that can pass through the switch without causing damage. Exceeding this limit can lead to overheating and potentially cause a fire hazard.

Only if they are placed in such a way as to make a straight line ,i.e., they should be placed at 180 degrees to each other.
The switch should always be on the HOT side. This way, when the switch is OFF, the light fixture is SAFE. Otherwise, you would have a HOT fixture with no clear return path when the swith is OFF -- very dangerous.
Simply put, the straight line is the on, and the circle is the off. These symbols represent an electrical circuit. The Straight line represents a closed circuit, which means the switch is on and the electric current can travel through it, and the circle means and open circuit, where the current cannot travel because the circuit is open. A quick trick to remember: "O, Open, Off".
