Making a switch to turn a motherboard on..?

[XA04]

I know I can turn a motherboard on by touching the two pins with a paper clip, but if I wanted to turn it off how would I go about it apart from telling the computer to shutdown or pulling the power from the PSU?

Obviously, switches you get with cases have a clip covering both pins constantly... so how would I go about turning it off? (I should be able to figure the rest out myself )


Cheers!

use the same method as you power it on, touch the pins with the paper clip and count 1,2,3,4,5,6 and it goes off

Or usually if you're logged in, just touching the pin will tell windows to shutdown.

This hasn't been the case since AT style powersupplies.
AFAIK, the power switches in todays ATX cases only 'make' the connection whilst your pressing them in. The motherboard takes closing of the circuit as an instruction to 'do something'.

What the power switch actually does depends on the current state of the PC, and ACPI/Power Management settings.

100% correct .

Can't remember the correct term, but it's something like a "Push to Make" switch that you'll want.

Maplin, and 10000000000s of other places stock varieties of said switches: http://www.maplin.co.uk/searchtempla...TON%20SWITCHES

At least in the US the terms are normally open (NO) and normally cloased(NC). Abbreviations are what you might see in a catalog. I believe you want a NC (Usually the pins are electricly connected).

That's great FatalSaviour, Cheers!

Think it would be a Normally Open switch for an ATX system surely (if the pins are not connected during normal operation?)
And no problem XA

Yeah, there just "push-to-make" switches.
- And as the other have said, a quick push will shut down the OS, and a 5sec hold with cut the power.

look on rswww.com at their piezo switches (theyre in automation strangely enough) they ar quite frankly the pimpiest thing ever.
