Abstract
A potentiometer device and a method for determining a number of closed DIP switches is provided, which belongs to the field of potentiometers. A DIP switch structure is connected in parallel with a potentiometer. The DIP switch structure at least includes a branch circuit formed by connecting one DIP switch and one resistor in series. Compared with a wire-wound potentiometer, a carbon film potentiometer, a straight slide potentiometer, and a rotary potentiometer, a design of a potentiometer controls whether a resistor is connected to a circuit by a DIP switch, can achieve a required voltage division ratio, high debugging speed, and high efficiency only by closing the switch, and there is no problem of slide wear, resistor body wear, or the like. In addition, the DIP switch has certain stability, a closing/opening state of the DIP switch will not be changed easily.
