I just received my power supply parts, overall they sent what I had ordered( from Ali Express) all except one which I'm almost sure it should be fine but I'm going to ask any way 😊 

I had ordered a one pole 12 position rotary switch, even though all I am going to need is a four position switch, what I received is ,a 3 pole 4T switch, I tested it with my multimeter and it looks like I can use any of the 3 poles with their corresponding four tabs,  am I on the right track here?

Yes, you're on the right track! 

If you wanted to be "fancy" you could even make use of the unused poles, like for a series of LEDs that illuminate to indicate the switch selection.

Yes that should be fine. There will be three independent "wafers" all of which will have four positions with the wiper all connected to a common shaft. You could for instance, wire all the three wafers in parallel so as each position has three switches contacting rather than one. I wouldnt do that because it would be ostentatious and unnecessary. Poor form (ugly). I say this by way of illustration. 

Just pick one bank, wire it up and leave the other two unused.
