How do I describe this circuit?

Do you want subjective opinion? Or technical description?

Subjective opinion would be: this circuit is badly designed, no matter what problem the designer tried to solve.

Technical description would be: it is a battery killer with stand-by indicator.


The best description for this circuit is "How to NOT control a light with a switch." This was clearly not designed by anyone with even basic knowledge of electricity. Or else it was incorrectly "interpreted" or reproduced by someone with absolutely no understanding at all.

Obviously, closing the switch will put a DEAD SHORT across the power supply. That is NEVER a good idea, and can be quite dangerous in many cases.

Clearly, the light bulb (or LED, it makes no difference!) turns OFF when the switch is closed. Anyone who thinks otherwise has zero understanding of electricity and should not be attempting to teach others. In any grade.


"Battery short circuit stress tester".

This circuit will allow you to observe how the supply source reacts when short circuited. Also tests the switch under extreme fault conditions as well. An expendable person should be deployed to operate the switch.
