Hello All,
I am intrigued by how this usb, with 2 white leds of different brightness works, can anyone help me understand it. First click turns on first lower intensity led, second click turns on 2nd led with greater intensity, 3rd click turns off both led's.
Notice the small metal disk with the dimple on it in pic2.
The metal disk, with the dimple, completes the circuit and pops back "rebounds back" after every click. The metal disk dimple is depressed by the plastic nipple seee pic9.
I see the pcb with the tracks.
Can anyone explain how the metal disk completes different circuits?
Does anyone know of a schematic with this same setup?
I purchased this usb led on ebay and took it apart. https://www.ebay.com/itm/JT-2-LED-F...var=502722800566&_trksid=p2057872.m2749.l2649
Thanks
