Subdivision of rocker potentiometer sensors

　　When the rocker potentiometer sensor is used as current regulation in the DC circuit, there will be current passing through the sliding arm of the rocker potentiometer sensor, and the resistance value will increase abnormally due to anodic oxidation. In this case, it is recommended to connect the terminal connected to the resistor to the negative terminal and the sliding arm to the positive terminal. If the DC current passes directly through the rocker potentiometer sensor, the anode of the rocker potentiometer sensor will be damaged by oxidation, so that the impedance of the rocker potentiometer sensor will be increased, so it is best to connect the negative electrode of the current to the terminal in contact with the carbon diaphragm, and the positive electrode to the terminal in contact with the brush (rocker potentiometer sensor contact piece).

　　When the rocker potentiometer sensor is used as a variable resistor, it is recommended to use as a voltage divider to adjust the voltage, and the load resistance RL of the rocker potentiometer sensor should not be less than 10 times the nominal resistance of the rocker potentiometer sensor RT.

　　It is used to adjust the output voltage in the regulator, so the design of the rocker potentiometer sensor should increase the output voltage when the clockwise adjustment is full, and decrease the output voltage when the counterclockwise regulator section is full. In the adjustable constant current charger, the rocker potentiometer sensor is used to adjust the bending size of the charging current. When designing the rocker potentiometer sensor, the current should increase when it is adjusted clockwise. When designing the printed board diagram, in the case of using the IC seat, we must pay special attention to whether the orientation of the positioning slot on the IC seat is correct, and pay attention to whether the various IC feet are correct
