It is an ideal component for white goods, automotive electronics, power tools, and other fields.

Operating Principle

This potentiometer uses a glass-fiber-reinforced epoxy laminate as its base substrate, with a carbon film resistor layer printed on its surface. Through a shaftless cross-slot or hexagonal socket mechanism, an external plastic knob or screwdriver drives the internal brush to rotate, thereby adjusting the resistance value and achieving precise potentiometer regulation. The shaftless drive design eliminates the drawbacks of traditional shaft-based structures, simplifying the overall architecture while enhancing the device’s impact resistance and ensuring stable adjustment accuracy, making it suitable for various applications requiring precise potentiometer control.
