The top of the housing 1 has a movable hole 101. The housing 1 is fastened to the support member 2 to form a mounting cavity. The joystick assembly includes an upper rocker arm 3, a joystick 4, and a lower rocker arm 5. The upper rocker arm 3 and the lower rocker arm 5 are arranged at a 90-degree angle staggered within the mounting cavity, and both are rotatably connected to the inner wall of the mounting cavity. One end of the joystick 4 passes through the upper rocker arm 3 and extends out of the movable hole 101, while the other end of the joystick 4 is fixedly mounted to the lower rocker arm 5. The first brush assembly includes a first slider 6 and a first brush 7. The slider 6 is mounted on one side of the lower rocker arm 5. The first brush 7 is fixedly connected to the first slider 6. The second brush assembly includes a second slider 8 and a second brush 9. The second slider 8 is mounted on one side of the upper rocker arm 3, and the second brush 9 is fixedly connected to the second slider 8. The carbon sheet 10 is provided with a carbon film layer and several terminals 11, all of which are connected to the carbon film layer. Several positioning holes 12 are provided on the carbon sheet 10, and the positioning holes 12 correspond one-to-one with the terminals 11, with the terminals 11 passing through the positioning holes 12. The rocker arm 4 can drive the first brush 7 and the second brush 9 to move on the carbon film layer, and obtain a resistance value at the output end that is related to the displacement of the first brush 7 or the second brush 9. With this configuration, several positioning holes 12 are added to the carbon sheet 10, and precise positioning is achieved through the positioning holes 12 to further ensure the positional accuracy of the carbon film during printing and finished product assembly.

The switch spring 15 is bonded to a predetermined position on the carbon film 10 via an adhesive film 21. During use, pressing the rocker arm 4 causes the lower rocker arm 5 to abut against the switch base 14 in a vertical direction, thereby pressing the switch spring 15 onto the carbon film layer to achieve the switching function. It should be noted that this pressing assembly can be selectively assembled according to the intended use to meet the pressing switch requirements of different application areas.

At the same time, within the tilt angle range, when the rocker arm 4 is pressed, the pressing assembly will be in a conductive state, and when released, the pressing assembly will be in a disconnected state.

[0047] In this embodiment, the 3D joystick potentiometer also includes a second pad 22, which is disposed between the carbon sheet 10 and the bracket 201, and the second pad 22 is made of insulating material.

[0048] Optionally, in order to prevent the outer shell 1 from falling off during assembly with the bracket 201 and to improve the reliability of the structural connection, the bracket 201 is provided with a number of inverted buckles 20 at intervals along the circumferential direction, and the outer shell 1 is provided with a number of anti-detachment grooves 102 along the circumferential direction.
