NC 9V LED circuit
NC 9V LED circuit
(OP)
I tried to build a simple LED circuit that is going to operate from 9V battery. When NC switch is closed I wouldn't want to draw any current, but this NC switch opens turns on red LED. Circuit I build was heating up the battery. My only requirements are low power consumption (so battery can last long time), fewer components-better.
Any suggestions?
Thanks in advance.

RE: NC 9V LED circuit
You have identified yourself as banderas(Electrical) and that has to have some ground. One is that you have learned to connect a battery and a switch and a load in series - not parallel. Have a look at your circuit. And, BTW, do not forget a current limiting resistor in series with the LED.

Sorry if my question irritated you,but I tried to build something really simple to indicate when NC switch opens.And I got stuck.I tried pasting my circuit to forum the but it didn't work.I know how to to this with the logic gates but I don't have power available.Thanks for your reply.

I did not mean to be mean
But sometimes people try to be funny. I thought that you were. Sorry if that made you feel bad. Does it work now?
