Metal Push button - Momentary w/ Blue LED

I bought this item a couple of days ago and i am wondering how to connect this.
I was assuming a schematic but didn’t find any.

Its a 5 pin switch with a + and - on the back, these are outerpins which i assume fuel the led inside.
The remaining 3 pins how do i use them??

I am sorry is this is kind of a dumb question but i am clueless for now, could anybody explain???

the left connects cathode of power,the middle connects GND,and the right one connects anode.
