i bought 2 anti vandal switches of aquatuning the led illuminated rings are rated for 12v. i know leds require a resistor. i want to run the leds off the power and hdd light headers on the motherboard. if i disassemble the switch to swap out the current smd leds for 3.3v smd leds i will require a different ohm resistor. i cant properly remember how to calculate the resistance required i know that the psu 3.3v output has a max current of 30 amps. I think the formula for calculating R is R=V/I
so if
v = 3.3
i = 30
r = 0.11 ohms
am i right or am i wrong.
also if i am right. do you think that this could work so to recap i want the on/off switch light to work as the power indicator and the reset switch light to work as the hdd activity indicator.
ooh another thing these momentary switches. for power i presume it should be wired for always off so when the button is pressed there is a signal to power the system. and reset switch i presume is an always on setup so when the button is pressed it breaks the circuit then re-engages the circuit. any help with this would also be handy as heck as the switches didnt come with instructions HAHA
cheers dudes and dudettes
