PCB relay trying to figure how to wire it...

[pepslight]

Hey folks my first time here.

I´m trying to mount LED inside my computer case, I bough 2 Led stripes going to use a molex 12v as a source. Now my problem is that I let my computer on very often and I want sometimes to switch those dam lights off. on my computer case, I only have a switch. When I press the switch the LED goes on and After releasing the switch the LED goes off. Im on my first year of electronic and funny enough we started last week doing Relays . so I bought a pcb relay that my light keep on when I release my switch and goes off after I press it, After buying my Relay and arriving home, I was all happy that I was going to finally do some practical use... And well i was surprised I just cant mannage to wire my circuit I tried everything. My biggest proble is the diagram, I cant figure it out. The diagram we used at school looks so different I dont have a clue were to wire everything.

On the cable counts:

From my pcb Switch I have 2 cables,

from my Power supply the 2 + and -

and to finish more 2 cables + and - from my Led strip


this bellow is the diagram from my PCB Relay RT424012

And I uploaded a picture of the relay I wired last week at my school... Is so different I dont mannage to understand the diagram above could anyone give me a help thank very much Peps.

I don't think you can do what you want with a single button and a relay.
You can wire a relay to act as a 'latch' so that when you push the button it turns on and stays on... but you would need a different button to turn it off.
In order to do what you want, you need a push-on/push-off button, or you need more relays to build a 'flip-flop' circuit with.

dam ok thx. Could you show me how to wire in a way that when I push the buttom it goes off ??? that would be awsome thx

I would suggest using a 'latching' type of push-button instead of the push-button you currently have. This would be the only part you need.
Is you have your heart set on using relays, I've seen a number of 'flip-flop' designs using 3 to 7 relays. You send a pulse to the group of relays and it will toggle the output each time you hit the button.
The design can be quite complicated and you risk short-circuits if wired incorrectly.

I will ask my teacher in the end how to solder a new buttom on my computer pcb. Thank you very much, I finally installed the led without switch and it looks really really pretty
