Hi,
I'm new to modding my case and therefor wiring in general, but I have a bit of and idea I've come on here just get get some experienced advice to help me so not to break anything. Any advice would be most welcomed.
I have just bought a new momentary switch for my case and was not 100% sure on the correct method of wiring. From my current case the wires I have are POWER SW, RESET SW, H.D.D LED AND LED +/-. All have two small wires (except the LED +/- which are single wires) going into a connection to connect in to the motherboard.
On the back of the switch it has a + and - pin which I'm assuming the LED +/- wires go on to. It has 2 pins labeled NO (normally open), 2 pins labeled NC (normally closed) and C (common). Now this is where I'm a not sure where things go. Do I need to wire all of them up or can I just do certain ones.
I know the all I need to wire up are the NO and C otherwise it will constantly boot loop my pc but do I need to put all the wires on the switch or can I just wire on the power button and the LED +/-.
I'm also unsure the difference between the H.D.D LED AND the LED +/- wires are there interchangeable or shall I only use the LED +/- on the pins. The switch does have LEDs in the button.
The question is do I need to connect the power the restart to the NO and C pins and the HDD LED and the LED+/- to the corresponding +/- pins. And do I need to make sure that both the pins on the NO are contacted (there is only 1 C pins). I have attached pictures to try to help visualise what I am trying to get across.
Thank you in advance for any help.

Don't connect anything but power button wires into that switch.
And in case of dual throw, which is change over switch, you need to use C and NO legs.
In case of switches polarity doesn't matter. (unless you're using transistor for that)
You'll need separate switch for reset, if you want that.

And never connect indicator LED outputs into any switch.
Those are for LEDs like it reads in them.
