This is a small electronic switch that connects a battery to the equipment for a certain amount of time when a push-button is momentarily pressed. And we have also taken the ambient light level into account; when it is dark you won t be able to read the display so it is only logical to turn the switch off, even if the time delay hasn t passed yet. The circuit is quite straightforward. For the actual switch we re using a well-known MOSFET, the BS170..
