These are very thin variable potentiometers. By pressing down on various parts of the rotary dial, the resistance linearly changes from 100Ohms to 10,000Ohms allowing the user to very accurately calculate the relative position on the rotary. Can be used as an accurate positional indicator for rotational items, variable user input (volume level input for example), straight user input (multiple button areas translate to given resistance levels), and many other applications.
