[0037] The base 2 and the face shell 3 wrap the part structure of the rocker assembly 4, thus playing a protective role to prevent external influences from affecting the normal operation of the part structure of the rocker assembly 4. The circuit board 1 is mechanically and electrically connected to the outside to realize power supply and signal transmission. The first TMR magnetic sensor chip 11 and the second TMR magnetic sensor chip 12 have the same structure and operation principle. The principle of the TMR magnetic sensor chip is to form a structure by sandwiching two magnetic layers between a non-magnetic layer. The non-magnetic layer serves as the contact of the sensor, and the magnetic layer allows current to pass through and can generate a magnetic field. When the external magnetic field and the magnetic field in the magnetic layer interact, the direction of the magnetic field changes, thus changing the value of the magnetic tunneling resistance.

Moreover, the TMR magnetic sensor chip has low power consumption, with power consumption to the level of microamperes, and has higher sensitivity. In addition to improving the sensing accuracy of the Hall rocker 41 switch, it effectively meets the use requirements of precision instruments that require low-power switches.

At the same time, the second magnet 45 on the lower rocker arm 43 is driven by the lower rocker arm 43 to rotate between the base 2 and the face cover 3, the second magnet 45 and the second TMR magnetic sensor chip 12 interact, the rotating direction and strength of the magnetic field of the second magnet 45 change, so that the second TMR magnetic sensor chip 12 senses different output voltages, the second TMR magnetic sensor chip 12 senses and transmits the sinusoidal change of the voltage according to the change of the position of the second magnet 45, and the magnetic core senses and cooperates, so that the direction and amplitude of the rocking of the rocker 41 driving the lower rocker arm 43 can be obtained, which is beneficial to improve the sensitivity and accuracy of the detection of the switch, greatly increase the service life and performance of the switch. And the switch avoids the use of the rocker 41 to drive the slider, the jamming feeling of the slider sliding against the base 2, and the problem of too many transmission mechanisms.

[0039] For the directions of the upper rocker arm 42 and the lower rocker arm 43, as shown in FIGS. 2 to 10, the upper rocker arm 42 is rocked in the X-axis direction, thereby driving the first magnet 44 to control the movement trajectory of the X-axis magnetic field in the switch, and the lower rocker arm 43 is rocked in the Y-axis direction, thereby driving the second magnet 45 to control the movement trajectory of the Y-axis magnetic field in the switch, and the two cooperate with each other, so that the switch can sense the multi-angle rotation of the rocker 41 with the X-axis and the Y-axis as the center, and effectively ensure the sensitivity and detection accuracy of the switch. The upper rocker arm 42 can also be rocked in the Y-axis direction, and the lower rocker arm 43 can also be rocked in the X-axis direction, which can be selected according to the actual situation, so in this embodiment, it is not limited specifically.

[0043] As shown in FIGS. 4-6, the rocker arm 41 penetrates through the upper rocker arm moving groove 422 and drives the entire upper rocker arm 42 to rotate through the upper rocker arm moving groove 422. The upper rocking shaft 423 rotates on the base 2, and when the rocker arm 41 drives the upper rocker arm moving groove 422 to rock in the X-axis direction, the upper rocking bracket 421 rocks on the base 2 with the upper rocking shaft 423 as the axis, preventing the upper rocker arm 42 from shifting and making the rocking of the upper rocker arm 42 in the X-axis direction smoother. The first magnet 44 is embedded in the hollow position of the upper hollow mounting member 424, thereby achieving its fixation, and when the upper rocking shaft 423 is driven to rotate, the first magnet 44 is synchronously driven to rotate, thereby being sensed and measured by the first TMR magnetic sensor chip 11.

The rocker 41 penetrates through the lower rocker 41, and the entire lower rocker 43 is driven to rotate through the lower rocker activity slot 433. The lower rocking shaft 434 rotates on the base 2. When the rocker 41 drives the lower rocker activity slot 433 to rock in the Y-axis direction, the lower rocking support 431 rocks on the base 2 with the lower rocking shaft 434 as the axis, preventing the lower rocker 43 from shifting and making the lower rocker 43 rock more smoothly in the X-axis direction. The second magnet 45 is embedded in the hollow position of the lower hollow mounting 435, so as to realize its own fixation, so that the second magnet 45 is driven to rotate synchronously when the lower rocking shaft 434 is driven to rotate, so as to be sensed and measured by the second TMR magnetic sensor chip 12.

[0048] Preferably, as shown in FIG. 5, the reset elastic member 47 is a spring. The spring has low price, high fatigue resistance, high elasticity, easy processing and assembly, and reduces the production cost of the switch, while effectively ensuring the feel and rebound power of the switch, and ensuring the normal operation of the switch.

In the embodiment, the rotating disc 49 is a circular shape with an upward protrusion on the upper end, and is fixed on the rocker 41 on the lower end. It can also be provided in various shapes and different heights for use, improving the application range of the switch and meeting the use needs of different users.

By setting a reset elastic piece 47 between the rocker 41 and the movable disc 46, when the user presses the rotating disc 49 and drives the rotating disc 49 to rotate, the rotating disc 49 drives the rocker 41 connected thereto to press downward and rotate, and the rocker 41 presses the reset elastic piece 47, causing the reset elastic piece 47 to deform. When the user releases the rotating disc 49, the rocker 41 drives the rotating disc 49 on it to reset upward under the elastic recovery force of the reset elastic piece 47, facilitating the next use. By setting the rocker 41 on the movable disc 46, the lower end of the movable disc 46 is connected to the middle part of the fixed support 5, thereby providing support force for the movement of the rocker 41, and the rocker 41 rotates at multiple angles with the middle part of the fixed support 5 as the fulcrum, thereby achieving the purpose of multi-angle rotation operation of the switch.
