+12V I'd suggest a separate power line or supply for them, depending upon your machine.
Lit buttons, regular buttons and more!!!

The led's require a +12V line. The buttons themselves require a +5V line. You need both if you intend to use the led's. For more info, Bryan's page:

hm. looks like you are correct. I have mine on 5v though through an LED-Wiz.. *confused now*
OP
OP
They will work with 5 Volts, they just won't be as bright. LED's work off a current flow, more current, more light. Each light has a resistor inside, the resistor is set to allow the maximum current tolerated by that LED at 12 volts. At 5 volts you will get about 1/2 the flow. I am working on getting some 5 volt LED's. Because I get the 12's with the buttons, and I will have to second source the 5's they will probably be 30-40 cents more. Milkit, I have a few in hand that I got for samples, I may be able to just through in an envelope for you to test out and see the difference.

oh right. they seem fine. Maybe ill connect my led wiz straight to pc power supply to see what the 12v looks like too (one of those 2 new sets im doing wont have an led-wiz anyways)
it says to connect it that way with a cable using an inline fuse. just have to figure out what I need to do that and ill test it. the 5v seems to look fine though *shrug*

Just to make it brighter, we should all go and get indutrial electric lines in out houses (480v) then a step up transformer to 600v, then remove the resistor. A few of these buttons and we could overpower the SUN!!!! 
Oh, and dont forget tons of these for your wiring:

Is there a limit as to the number of buttons you should run off a power supply, and what type of power supply would you recommend using to power the leds? The cabinet I am building will be a 1XXX in 1 board that requires an ATX and switching power supply to run. I plan on installing around 30 of the led buttons.

Depends on the power usage of the components and the wattage of your power supply. Add 100w to whatever your board says it needs and it should be plenty for all the buttons you could want - just make sure to run em off a different rail than the main pcb
OP
OP
I measured the current flow through these and its about 30-40 mAmp, So the ee cummings silentninja is exactly right that adding some power will help, however, at 30-40 mamp, 30 buttons is only 1.2amps, and at 12 volts, that's roughly 12 watts(ok 13.2 to be exact, I was engineering, not math)....seeing as most 600 watt power supplies have at least 12 amps available to the 12 volts line, I'm thinking that you should be fine....

Just avoid the cheapo sub-$20 250-300w power supply and youll be fine
As armi said, 600w will power most anything your gonna have in an arcade machine (unless its a mame tower w/ an i7 cpu and an sli setup...)
Ill have to jot down that draw somewhere for future ref
The budget option of course is to power them w/ about 3 hamsters on wheels (or in one of those new cube cars we keep seeing on tv) but in the long run since you have to feed em it dosnt pay off

Thanks for the reply guys, but I have just one more question. Will running the leds in series require the use of a resistor? This whole led thing is new to me, and I have 30 buttons waiting to be installed.

Nope, just wire em straight down the line - resistor is built into the led

Hmm, when I initially wired mine up with +5V instead of +12V, I had no light at all. When I added a separate power supply and provided the +12V line, they were nice and bright. So, I used a cheap and small separate 250w power supply for the leds on both machines I've put them on so far. About to add some to a special cocktail I'm building within the next week or two.
OP
OP
The easiest thing to do is just grab the power to the door. I would go with a 500-600 watt power supply for the KE board just to be safe, but that's probably quite a bit of over kill. However they are only 30 retail and you can probably grab one for 10-20 on CL.

Now that you mention it, I recall trying to do that briefly on my bartop, but without a coin door there really isn't a line I could safely grab in there without pulling too much power from the monitor. I have a 550W power supply in there with the Killer Edition system and the led's are being powered off a separate rail than the jamma harness. It's only 6 buttons right now, so not much of a power draw anyway.
Hopefully he doesn't kick me for this, but Bryan will respond to questions relatively quickly if you have any. If not, he's busy and will respond as soon as he can. He's been great with my button orders, so don't hesitate to ask question or order from him!

Thanks everyone, I would go over power, at 500-600, hit cl, honestly that's what I would do for the ATX. OK....button update....
Gladiator.....printed...woohoo
Color changing Galaga, up and going, just need to optimize
All orders are shipped and we are going to take a deep breath on Sunday and be ready to ship on Monday.
Our online store is 90%, I am setting up a KLOV/forum specific page! it will be up and running in the next few days.
Quick question....would people be interested in a custom Jamma harness with the power to the buttons built in?

I have two of those blues.... and I have a few 55 warm white bulbs for testing. I have been focusing on boards because the LED guys are taking toooooo long to get back to me, I will be dropping an order for smd blues in the next 3 weeks and then I will have enough I am sorry, I thought you needed one originally and just snuck it in on a sample run, and I was quite frankly dissapointed with the frosted bulbs I got on sample
