Potentiometers provide a controllable resistance that can be varied by turning a shaft, sliding a carriage or pressing a membrane strip. They are common in user‑interface panels, sensor circuits and analogue signal conditioning, offering linear or logarithmic tapers to match the desired response curve. Form factors range from panel‑mount rotary shafts and dual‑gang units for synchronised control, to compact slide pots with solder tabs or pins for PCB integration, and ultra‑thin membrane versions for space‑constrained layouts. Key attributes include mechanical robustness, predictable taper characteristics, straightforward wiring and compatibility with most analogue inputs. Selecting the appropriate type, rotary, slide, thumbwheel or contact‑less, depends on the required travel, mounting method and the way the resistance change will be interpreted in the circuit.
