Power switch help!

post #1 of 8
Thread Starter 
So after ordering the below switch i have decided to use my motherboards original breakout cable for front panel connections (power, power led ,HDD led) i want to wire up the power led termianls to the swiches LED so when i turn it on the led powers on when the pc is on
The provided diagram is confusing(probably just to me) as this isnt its intended purpose.
i was hoping to have the power cables to the 2 contacts on the switch and the led on 2 others but it looks like they share common earth etc.

www.ebay.co.uk/itm/122009748600?_trksid=p2057872.m2749.l2649&var=421011813302&ssPageName=STRK%3AMEBIDX%3AIT

Could anyone advise how to do this?
Thanks,
Tom

Edit: added diagram

Wrong switch.

That switch takes whatever power you send to it and switches it "on" or "off",
It also only turns on the light when the switch is turned off (ie. the light goes out when the switch is "on").

The power button on a computer just makes a (momentary) contact when you press the button in.

You need a lighted, momentary contact switch. But that type of switch will have the light on all the time.

I'm not aware of any type of switch that does what you want.
To do what you want you'd need two switches:
One lighted momentary contact switch (to start the computer).
Another on/off switch to turn the light in the momentary contact switch above on and off.




What you want to do can be done, it's just not simple to do.

thanks, but i think you may have missed my point, i know this switch does what i want.
It has a built in LED that (on most switches like this) can be powered by a positive and negative not linked to the terminals you are using for the momentary.

To clarify the switch i have linked from ebay is the one i have bought and i need someone to explain how to use the power LED pins (from themotherboard) to power the led in this switch.
also i am aware of how a momentary switch works, thanks for the diagram.thumb.gif

any suggestions on how to connect the MOTHERBOARD "power led" connections to the led connections in the switch i mentioned would be greatly appreciated.
Tom

If you have them just snip the wires and solder (or crimp - sux!) on connectors for the switch.



That assumes the the power supplied at that motherboard connection is sufficient for powering the light.

Ok so those two connections were the power led connections I was talking about, and what I want to know is how I would use them to power the 12v led inside the momentary switch, because the diagram from the manufacturer of the switchs wiring is confusing

First you have to find out what voltage the motherboard supplies to the PLED pins. You're assuming it's 12 volts. It may be only 5 volts.

From the eBay link:
Technical Specifications
Rated Voltages (DC): 6V/12V/24V

That being said, instead of the PLED connection (of questionable voltage) on the motherboard why not use 12 volts from a spare SATA or Molex connector to power the LED?

And that being said:
