Adjustable potentiometer is a kind of adjustable electronic component, composed of a body and a rotating or sliding system. On the bare resistor body, one or two movable metal contacts are pressed tightly, and the contact position determines the resistance value between either end of the resistor body and the contact. When a voltage is applied between the two fixed contacts of the resistor body, the position of the contact on the resistor body can be changed by rotating or sliding the system, and the position of the movable contact can be obtained between the rotating contact and the fixed contact. A certain relationship of voltage. The potentiometer is basically a sliding rheostat. There are several styles, which are generally used for the volume switch of the speaker and the power adjustment of the laser head.
