Power Saving Switch System Design

Saving electricity can become a problem for busy families, as kids just forget to switch OFF lights when there is no need of it. Researchers at the University of Standford have come up with a ingenious solution to this very problem. They have designed a system in which for example you wish you switch ON another light the switch will get a bit rigid and resit your push. This is actually an indication that there are enough switches already ON in your house therefore you should first switch them OFF to reduce the load stress.

Here is a demonstration video of the designed system:
