Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of potentiometer, especially a rotary potentiometer with one-way lifting. BACKGROUND

[0002] A potentiometer is usually composed of a resistor body and a movable brush. The resistor body is made of metal or carbon film and has fixed resistance characteristics. The brush is a movable contact that moves on the resistor body by rotation or sliding, thereby changing the contact area with the resistor body and affecting the resistance value. When the brush moves, the resistance value or voltage related to the displacement can be obtained at the output end. The potentiometer has three output terminals, so it can be used as a three-terminal element or a two-terminal element. As a two-terminal element, the potentiometer can be regarded as a variable resistor for current control in a circuit. As a three-terminal element, the potentiometer is more commonly used as a voltage divider to obtain the required output voltage by adjusting the position of the brush.

[0003] A potentiometer is disclosed in Chinese Patent No. CN212032778U, which includes a potentiometer body with a potentiometer seat.
