SparkFun's Description of the SoftPot Membrane Potentiometer - 50mm
These are very thin variable potentiometers. By pressing down on various parts of the strip, the resistance linearly changes from 100Ohms to 10,000Ohms allowing the user to very accurately calculate the relative position on the strip. Can be used as an accurate positional indicator for CNC head positioning, variable user input (volume level input for example), straight user input (multiple button areas translate to given resistance levels), and many other applications.
Unit comes with adhesive backing. Connector is 0.1" spaced and bread board friendly.
Note: These potentiometers work great with a finger, or stylus.
