A battery torch that turn’s itself off after a few minutes

Dec 08 2013

Why is this necessary?

Because children loves to play with batter torches. But they don’t remember to turn them off. And grown ups are not that keen on buying new batteries.

A remedy could be to have rechargeable batteries. But it still means the batteries get discharged, if not worn out, and there has to be an extra pair to swap with.
