On load switching is when a switch can be operated whilst current is still passing through the switch (i.e. it is on load)
Offload switching is when a switch is operated whilst there is no current through the switch (i.e. it is offload)
A light switch is an on load isolator while the main switch is an off load isolator.
NO stands for Normally Open and NC is Normally Closed. It references a switching application. It is the base state of the switch. So if the load is connected to the NC terminal it will usually be energized and when the switching device is activated the circuit will open and the load will be de-energized. The NO terminal would have the load de-energized until the switch was activated and then it would be energized.
In electrical system load means circuit carrying current . Isolator is device which make on ( Connect ) and off ( Disconnect ) of circuit from supply. When load is ON means carrying current and required to disconnect from supply , than is called on load isolation.Here required on load isolator. When load is OFF means not carrying current and required to disconnect from supply , than is called off load isolation.Here required off load isolator. On load isolators design is more precise than off load isolator because while isolating load during ON states create heavy sparking and transient voltage spikes.
Normal power supplies are on all the time while switching type are on and off periodically which results in precise control and improved efficiency.
The cut-off point is the exact point where the load line crosses with the vector axis. The saturation point is the point where the load line intersects with the collector current axis.
switching on the tourch for example is when as you switch it on it will move the switch connecting it to a circuit that lights up the bulb and when you switch the switch off the switch will move breaking the circuit
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.

all three of the phases
Do the 'old favourite' of switching the phone off and on again. Switching the phone off - severs the connection to the internet.
On-load tap-changing is done in electric power supply systems to maintain the supply voltage to customers within limits. Tapping is done by switching extra turns in or out, usually on the high-voltage winding of a transformer. The switching is done by a make-before-break switch to avoid excessive sparking in the transformer, and this enables the switching to be done without interrupting the supply.
Not for many years.
it is switching when the p c is off
