Okay you might get this a lot around here; I'm trying to figure out the inner workings of this specific potentiometer like component. I want to get my hands on the datasheet or a similar components datasheet.
It is used to change the volume of the device in question. Rolling is infinite in both directions, it has a small click. I tried measuring it's workings with the multi-meter but I'm baffled by its working.
One click in either direction shorts all three pins. The very next click measures a 620ohm between the three pins, along with a 3.2v between pin 3 and 1/2.
I'm a real noob on electrical engineering, never came across something like this.
