Double white dial potentiometer volume adjustment knob switch HY-B501

potentiometer is a resistance element with three lead-out terminals, and its resistance value can be adjusted according to certain changes. Potentiometers usually consist of a resistive body and a movable brush. When the brush moves along the resistor body, a resistance value or voltage related to the displacement is obtained at the output.

potentiometer

potentiometers are also commonly referred to as potentiometers or potentiometers. It is a manually adjustable variable resistor with 3 terminals. Two terminals are connected to both ends of the resistive element, and the third terminal is connected to a sliding contact that moves on the resistive element, called a wiper.
