Automatic Switch

The position of light switches in many school dormitories were designed inappropriate. We have to leave the warm bed to turn off the light and climb to bed in the dark.
This automatic switch is a combination of mechanical timer and spring mechanism. You just need to stick it beside the light switch, then turn on the knob and go to sleep.
