Aim
Every time you use a fan in a room it involves two steps:
• Go to the switch board and switch on the fan. It will run as long as it is switched on.
• When you leave the room, you must reach the switch board again to switch the fan off.
If you forget step 1 and get to work without switching on the fan, you have to get up and go to the switch board to switch it on. If you forget step 2 and leave the room without switching off the fan, it will continue to run even when there is no one in the room, resulting in wastage of electric power.
