I am just trying to find a schematic for the LED momentary push button switch that I ordered from the MP3car online store.. I cant get the LED to illuminate. The switch does work though it does not illuminate.
No it did not ...
Though I figured it out.. Basically the two center connections + and - are to illuminate the switch.. However it does not make much sense because you would need to have that connection switched...
Then connections 1&2 and 3&4 are switched when pressing the button.
the idea behind a switch like this is that the switch stays illuminated no matter what to allow to easily locate the switch-- many automotive-specific switches are as you describe, where the led is only lit while the switch is on..
Hey mp3car - who sells a switch without some sort of wiring instructions? Not everyone has experience with automotive switches...
They also need to update their sales page so that people know this will stay lit all the time, so people aren't surprised when they leave for a week and come back to a dead battery.
Honestly, did anyone review the ad or the product packaging?
The beauty of having the lighting independent of the switch, that way you chose if lit full time, or when on, or when off.
(I don't mind pre-configured, but it should be user changeable! Not to mention being able to use other voltages.)
I have an idea that should work.. Though I wont be able to test until later.. If I tap into the the cluster lighting for the 12 volt power then the button would illuminate only when I had the lights on. Which would be the only time I would really need it illuminated.
Alright it is confirmed, though the lighting on my vehicle (2005 Mitsubishi Montero Limited) works a bit differently causing the LED push button to fully illuminate when the dimmer is turned down all the way, and oppositely dim when the dimmer is fully illuminating the dash lights. Oh well a good medium will suffice for both the dash and button..
In case the question arises.. Yes I attempted to reverse the polarity through the switch though no change. The dash lighting throws 12V both ways across the instrument illumination.. Making me wonder if all the lights are operating with a special diode that allows voltage to pass by removing removing voltage.. ??
Oh well, it works..
