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.

The silk screen identifier 'SW2' gives a clue that it is a type of switch rather than a potentiometer.

That's a co-incidence, I just took my mouse apart to clean mine up a bit. It still sticks though.

That's a rotary encoder - not a potentiometer. The encoder pulses are sent to the microcontroller which adjusts the volume of the system.
Figure 1. 2-bit rotary encoder waveforms. The relative phase of the signals indicates clockwise/anti-clockwise rotation and can be used by the controller to count up or down.
