In [http://www.alps.com/products/e/category_multi.html ALPS] webpage are only available sticks with 3 pins pots, there are two posible explains for this, maybe ALPS manufactured the sticks without pots and sony ordered this special version of the pots to other company then sony asembled the pots and sticks together.... or... ALPS made an special production of sticks with 4 pins pots. anyway, this pots with 4 pins are a bit special

In the boards where this component is present (or his replacement upgraded versions) every stick has two pots (to meassure rotations of X and Y axis of that stick), and every pot has 2 pins that are carrying the signals related with the rotation of the axis (pin 1 and 2 of the pot). This signals are voltages, but there is also another pin of the pot that has an additional voltage (pin 3). Inside the pot there are two separated voltages, this seems to create a magnetic field with a [https://en.wikipedia.org/wiki/Magnetoresistance magnetoresistive effect]. Also this allowed them (in further versions of the pots) to separate the mobile parts inside the pot by an intermediary "seal" that prevents dust and degradation of the parts

So... this component is the initial version that gives support for this "special sticks with 4 pins pots"
