Yes it is safe to handle the bulb when the switch is OFF.
Reason:
The bulb when the switch is OFF.
- When an electrical circuit is turned off, an electric field doesn't created in the entire conductor due to the voltage from the source not connected to the circuit, regardless of the length of the conductor. This electric field causes all electrons to stop in a given direction at the same time. So the light is off.
The bulb when the switch is ON.
- When an electrical circuit is turned on, an electric field is immediately created in the entire conductor due to the voltage from the source connected to the circuit, regardless of the length of the conductor. This electric field causes all electrons to move in a given direction at the same time. So the light is on.
