As shown in fig. 1 to 4, a hall rocker potentiometer 10 includes a housing 100, a reversing assembly 200 and a signal assembly 300, the reversing assembly 200 includes a first rotating shaft 210, a second rotating shaft 220, a rocker 230 and a reset member 240, the first rotating shaft 210 and the second rotating shaft 220 are both rotatably disposed in the housing 100, the horizontal projection of the axial direction of the first rotating shaft 210 is perpendicular to the horizontal projection of the axial direction of the second rotating shaft 220, one end of the rocker 230 is rotatably connected to the first rotating shaft 210, the other end of the rocker 230 is disposed on the second rotating shaft 220 and extends out from the top of the housing 100, the reset member 240 is disposed below the rocker 230, the reset member 240 is respectively abutted to the rocker 230 and the housing 100, the signal assembly 300 includes a circuit board 310, an IC chip 320, two magnets 330 and two hall sensors 340, the circuit board 310 is disposed on the outer side wall of the housing 100, the two hall sensors 340 are both disposed on the circuit board 310, one end of the two magnets 330 is disposed on the first rotating shaft 210, the other end of the two hall sensors 340 is disposed on the two opposite ends of the two hall sensors 330, and the two hall sensors 330 are respectively aligned with the two magnet 330.

It should be noted that, the first shaft 210 and the second shaft 220 are rotatably installed in the housing 100, wherein the projection of the axial extension direction of the first shaft 210 and the projection of the axial extension direction of the second shaft 220 on the horizontal plane are perpendicular to each other, that is, the first shaft 210 and the second shaft 220 are mutually crossed. Thus, when the hall rocker potentiometer 10 is placed horizontally, one of the first and second shafts 210 and 220 can be ensured to reciprocate along the X-axis direction, and the other can reciprocate along the Y-axis direction. Further, one end of the rocker 230 is connected to the first rotating shaft 210, and the other end of the rocker 230 passes through the second rotating shaft 220 and protrudes from the top surface of the housing 100. The reset member 240 is installed in the housing 100, specifically, the reset member 240 is located below the rocker 230, and the reset member 240 abuts against the bottom of the housing 100, so that the rocker 230 is maintained in a vertically upward state by the pushing force of the reset member 240. Further, the circuit board 310 is adjacently mounted on the outer side wall of the housing 100, the IC chip 320 is soldered and fixed on the circuit board 310, for example, the IC chip 320 is a single chip microcomputer, the two hall sensors 340 are also soldered and fixed on the circuit board 310, and the two hall sensors 340 are electrically connected with the IC chip 320. Two magnets 330 are respectively mounted on one end of the first shaft 210 and one end of the second shaft 220, and the two magnets 330 are aligned with the two hall sensors 340, respectively. In this way, compared with the prior art, in the present application, the two magnets 330 are independently installed at the end positions of the first rotating shaft 210 and the second rotating shaft 220, so that the rotation amounts of the first rotating shaft 210 and the second rotating shaft 220 are respectively measured by the two hall sensors 340, and the two magnets 330 are both far away from the reset element 240, so that the reset element 240 can be effectively prevented from interfering with the magnets 330, and therefore the precision and reliability can be effectively improved. It should be noted that, when the rocker 230 swings, the hall sensor 340 also known as a magnetic field sensor drives the first shaft 210/the second shaft 220 to rotate, so that the magnet 330 rotates relative to the hall sensor 340, and the hall sensor 340 converts the magnetic field change into an electrical signal change due to the magnetic field change, so that the changed electrical signal is transmitted to the IC chip 320 to be converted into a corresponding movement amount of the first shaft 210 or the second shaft 220, and the IC chip 320 sends the control electrical signal to a handle motherboard connected to the hall rocker potentiometer 10. Because the magnet 330 and the hall sensor 340 are in a non-contact structure, the service life can be effectively prolonged compared with the use of carbon brushes to detect the rocker switch. Further, since the IC chip 320 is integrated on the circuit board 310, the magnetic field variation signals detected by the two hall sensors 340 can be directly converted and calculated on the IC chip 320 into electric signals corresponding to the movement amount, so that the hall rocker potentiometer 10 of the present application can be directly replaced in various handles, and thus has good compatibility.
