Expert Answer
Even though the drift speedof electrons is very low, the bulb or any other appliance are switched on quickly because there are are billions of electrons per square area of the wire.
This large number of electrons contribute to a significant amount of energy enabling the appliance to be switched on immediately after the switch is pressed.
