Hey here is your answer bro

Switch ON
When the switch is on its an close circuit
in which all wires and the switch is connected to all the part without any gap so that the electricity can flow through all parts and switch and the results is the on fan or moving fan and blown bulb







Switch OFF
when the switch is off it's an open circuit or you can say it broken circuit
in which there's a gap in between of all wires and switch that's why the electricity can't flow through to all parts and the result is off fan and unblown bulb

Switch ON

When a switch is turned on, it completes the circuit and allows the flow of electric current through it. Here are some key points to differentiate between switch on and switch off:

- Circuit Completion: When a switch is turned on, it closes the circuit, allowing the electric current to flow from the power source to the load connected to it.
- Flow of Electric Current: In the on position, the switch allows the flow of electric current, which can then power up devices or appliances connected to the circuit.
- Light Indicator: In many switches, there is a light indicator that turns on when the switch is in the on position, giving a visual cue that the circuit is complete.

Switch OFF

On the other hand, when a switch is turned off, it breaks the circuit, stopping the flow of electric current. Here are some key points to differentiate switch off from switch on:

- Circuit Interruption: Turning off the switch breaks the circuit, preventing the electric current from reaching the load connected to it.
- No Flow of Electric Current: In the off position, the switch stops the flow of electric current, effectively shutting down the devices or appliances connected to the circuit.
- Energy Conservation: Turning off switches when not in use helps conserve energy and reduce electricity consumption, which is beneficial for both the environment and energy bills.

In conclusion, understanding the difference between switch on and switch off is essential for using electrical devices safely and efficiently. Knowing when to turn a switch on or off can help prevent accidents, save energy, and prolong the lifespan of electronic appliances.
