The SoftPot (Linear) Membrane Potentiometer is a resistive element, it comprises a conductive resistor, a sealed encasement and a simple wiper assembly. A membrane potentiometer can also function as a voltage divider. The SoftPot (Linear) Membrane Potentiometer is a three-wire system with two resistive output channels and an electrical collector channel. By pressing a wiper down onto the top circuit the SoftPot (Linear) Membrane Potentiometer produces the desired electrical output. The "wiper" is a non-conductive mechanism that depresses the top circuit actuating the potentiometer from the outside of the element. The top and bottom circuits are separated by 0.15mm (0.006³) of spacer adhesive build-up and contact between the circuit occurs by pressure (usually 1-3 Newtons) from the wiper on the top circuit, pushing down until the top circuit connects with the bottom circuit to create a potentiometric output. The construction of the wiper design can adapt to any application because most materials can serve as the wiper: plastics, metals, sliders, rollers, wheels, etc. Also, the SoftPot (Linear) Membrane Potentiometer can also be manually (hand) actuated.
