Problem: The switch can only be switched off when the time is up. So if you were to turn the timer to 10mins, you will have to wait until 10 mins is up to switch it off, if you decided to switch it off.
Solution: add a switch to the circuit.
This will solve the problem as it will allot the user to immediately break the circuit, even though the timer is still on, in order to switch the switch off.
