Allright. Have you read Pyrofers Post? It is similar to your posted image and the circuit you can see there should be your master plan. Do you have questions regarding this circuit?

It wouldn't hurt to sling in an opto-isolator too of course.

So if I understand it the right way, the easiest one is the NPN Relay sitch circuit?

I got a little question, which specific data should the relay itself got?

So in terms of current and voltage specifications (so that i knew what I should search for)

Cheers,

Yes, we suggest using the NPN-Circuit.

To be honest, i am not quite sure whether you have enough basic knowledge to achieve further progress - i suggest to read a bit more about basics.
The specific data you asked about is very depending on your circuit, environment and function it should provide.

Yep, that circuit would work just fine; however, you could use this for an easier solution:

good luck :)
