I would quite to have an additional on/off switch installed into my desk because my PC is nearer to my simracing rig than my desk. I'm thinking of buying this switch to turn my PC on/off (link: http://www.scan.co.uk/products/phobya-71135-push-button...) and another one for the reset switch in another colour. I know how I am going to mount the switch but I'm not sure how I am going to be able to wire it up while still keeping the switches that are on my case. Is there a way to do this?
Thanks very much! :)

Wire them in parallel. Activating either switch completes the circuit, and power on.

S1 & S2 are the existing power on, and the new remote power on.

Computer on/off and reset switches do not have an on and an off position . They very briefly short their respective pins which kicked the board in to life . If the switch continues to make the circuit the pc wont run .

Theoretically you could connect any number of "switches"to the headers on the mb by splitting the cables to the case switch and start using any of them . But you wont be able to use an on/off switch

All the power switch does it complete the circuit, connects the + and -. So you just need to make a splitter so to speak that goes to the new switch along with the current one.

These switches are momentary, all they do is form an electrical connection from one pin to another on the motherboard while pressed.
You can easily wire a second switch in parallel. You could connect each of the new switch wires on the same motherboard jumper or on the terminals at the back of the switch. If these aren't exposed, you may have to cut the existing wires to access them, but when it is back together the wires coming from the back of the motherboard still need to go directly to the existing switch and the new switch. Make sure you cover any exposed wire in electrical tape so it doesn't make contact with other wires or other components including the case.

The switches you have chosen should work fine. This statement however is a load of crap "These push-buttons were especially designed and manufactured for 12V operation, therefore no additional resistor is needed." A 12V rating on a switch is just the maximum voltage it can handle. You would expect the resistance of any switch to be close to zero when closed and for practical purposes infinite when open.

Right. It needs a momentary switch. My image was just showing what a parallel circuit looks like.

Thanks very much for all of your responses! Do you know how you would split the switches? Been looking for a splitter but can't find any.

You may need to do some soldering and make it yourself.

Ok does it matter if I wire pins 1-4 into either positive or negative? Apparently this is an SPCO switch (NO meaning open contact and NC meaning closed contact).

You want pins 3 & 4. 'Normally Open'

So pins 3 and 4 as well as the positive and negative for the LED?
Thanks very much for all of your help! :)
