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.
The HotPots are ideal for higher temperature environments, but many users also find that the HotPots which are made out of a impregnated fiberglass material, 'feel' better than the SoftPots which are made out of a polyester base. If you're planning on using these pots with finger contact (versus with the actuator), you may want to consider using the HotPot line.
