    Recently, I am studying the potentiometer, and I think it's a little hard for me. I can only understand little.

    Today, my friend ask me what the potentiometer models in the following picture is, actually, I have no idea.

    So, do you know it? If you know, could you please tell me? Thanks a lot.

    Looks like a potentiometer with integrated switch. Show us more detail: there seems to be an inscription on the bottom of the device which usually should indicate the model.

    To learn about potentiometers, it is very convenient to dismantle one and observe its construction carefully.
    Or, look at ---->
    There is several flavors, stacked, switched,...

    Looks similar to this one but with a diffferent shaft. Can you measure the resistance of the potentiometer (end-to end, not wiper)?
