The invention provides a high-performance magnetic rotation positioning potentiometer. The operation hand feeling of the potentiometer is enhanced by introducing a magnetic rotation positioning technology to the traditional potentiometer. The high-performance magnetic rotation positioning potentiometer consists of a substrate, a rotating shaft, a magnet, a positioning toothed plate, a magnet frame, a circuit board and a shell; the center of the substrate is provided with a shaft hole for installing the rotating shaft, the rotating shaft partially passes through the shaft hole of the substrate to sequentially install the positioning toothed plate and the magnet frame or a leaf spring frame, and the rotating shaft is fixedly installed with the positioning toothed plate and the magnet frame or the leaf spring frame; the magnet is installed in a magnet groove of the substrate; one end of the magnet frame is provided with the magnet or one end of the leaf spring frame is provided with a leaf spring, and the magnet or the leaf spring corresponds to positioning teeth; the circuit board is fixedly installed in the shell and sequentially provided with resistors which are sequentially connected in series, a magnetism-sensitive switch is installed on a contact between every two resistors, the other ends of the magnetism-sensitive switches are connected in parallel to form a middle-point output end, and the head end and the tail end of the resistor series-connection group is a potentiometer output end; the shell is fixedly installed on one end, which is used for installing the positioning teeth, of the substrate, and the position of the positioning teeth is corresponding to the position of the magnetism-sensitive switches.
