ATX switch

tim-may · 06-24-2002, 09:25 PM

does anybody know if an ATX switch is a momentary switch or toggle switch?

Hixup · 06-24-2002, 11:24 PM

isnt atx a brand? well does it say normaly open?

Brad · 06-25-2002, 03:33 AM

atx is a form factor, which covers everything from cpu positions to how the power supply is turned on.

the atx power switch is a momentary switch

bigben2k · 06-25-2002, 06:55 AM

Actually, it's a toggle switch...

A momentary switch is a switch that acts much like a doorbell button: momentarily on.

thanx bigben. someobdy knows what im tlaking about...

im going to be wiring up an alternative power switch (key ignition) and it does both. i just needed to know which way to wire it up.

thx again

I thought the atx switch was momentary?

Nope... they're push-on, push-off, but they stay in their on or off state, so they are not momentary, they are toggle.

Brad · 06-27-2002, 04:43 AM

how come the momentary switch I use in my case works just fine then?

bigben2k · 06-27-2002, 07:38 AM

You would have a momentary switch, if you have that type of connection to your PSU.

I use a Compaq computer here, and there's a momentary switch on it. I haven't opened it up (yet!) but I'm sure I'd find that it is connected to some little circuit board, either inside or outside the PSU, that activates a relay.

I believe that the PSU we buy never come with that option though. As far as I know, they all have those 4 wires: white, black, brown and blue. The toggle switch links those to turn on the PSU.

That sounds like an AT psu

bigben2k · 06-28-2002, 11:11 AM

I have yet to see an ATX psu, so you might be right!!! I don't know.

MeltMan · 06-28-2002, 11:35 AM

ATX has generally two switches. One in the back on the psu itself, and one on the case in the front. The one on the back is a toggle to actually physically disconnect the power from the outlet to the psu. The other switch is a MOMENTARY pushbutton switch. It basically just shorts the 5vsb with a ground and powers up the psu. But, there is a catch, the motherboard will have to hold the psu in the on state by keeping the 5vsb shorted with ground.

so simply put, its a normally open momentary pushbutton switch.

bigben2k · 06-28-2002, 11:53 AM

Thanks for the clarification MetlMan! I hope that Tim-may can use it now!

Brad · 06-28-2002, 03:16 PM

I think he gave up on us about 3 days ago :P

tim-may · 06-28-2002, 03:30 PM

nah, im still here.
just my stupid hotmail keeps thinking ATX is a bad word

i just finished reading the thread, and i think i should have been more clear about my question.

im talking about the one that you plug into the motherboard. its 2 wires (white and green). i know about the master switch on the back of the PSU but that doesnt turn on the computer.

now the switch i have on the case i have on there now (which i want to replace) sounds like its a toggle (like a click on/click off sound) but it springs back like its a momentary switch.

so which is it, momentary or toggle?

jtroutma · 06-28-2002, 11:08 PM

Momentary. Only connected when depressed. The Motherboard is in charge of telling the PSU when to turn on and turn off.

tim-may · 06-29-2002, 03:49 AM

so....momentary (normally open) is the type of switch that turns on my comp?

are we sure now?:shrug:

Brad · 06-29-2002, 06:28 AM

Tim - yes thats a momentarily on switch

but now we know the difference between AT and ATX (especially me

)

MeltMan · 07-03-2002, 03:21 PM

Mainly the big difference is the lack of a 3.3v line on an old AT PSU.
