please look at the following.


schematics



i am trying to figure this out.

i'm using this switch to ground my av electronics nav box unit (for testing purposes of course)

so basically. input ground and output are easy, but I dont' understand where the resistor goes and how the led light is going to get power.

anyone with good wiring skills help me out?


thanks!

 

The resistor is a dropper to lower the voltage across the LED. The LED drops .6v across it and applying 12v would fry it.

Wire the resistor in series with the LED....12v at the anode end of the circuit, system ground to the LED cathode.

 

Check with lurch519.

 

English please. lol


1. I run the ground wire into the input.
2. I have another wire coming out of the output. This switches the ground on or off therefore switching the unit either on or off.

Then what?

I understand what a resistor does, but how does the led get power? Like Do I bring a +12 v in here somewhere, then hoook it up to the resistor then the resistor to the led power? also how does the led ground get grounded? what is the jumper wire thingy?

Help. I need to install this asap. Thanks!

 

anyone?

 

? i have to put my car back together quick thanks for the help.

 

Is this a note of sarcasm???

Guess you could always pay some one in your area to give you an answer right away
or you could wait until someone here (with the answer) stumbles across this thread...

Sorry I (we) didn't have an answer for you...
Perhaps you should do a little research before you start tearing stuff apart....
