Embodiment Construction
[0015] Such as figure 1 A miniature joystick based on a Hall sensor as shown includes a base 1, and the inside of the base 1 is provided with a Hall sensor 2 and a circuit board 3, and the Hall sensor 2 is arranged above the circuit board 3. Above the base 1 is a reset structure 4, above the reset structure 4 is provided a dustproof cover 5, and the top of the dustproof cover 5 is an operation cap 6 for manipulation by fingers.
[0016] As a preferred technical solution of the present invention, the insulation withstand voltage of the Hall sensor 2 is 3KV.
[0017] Further, the joystick can realize the manipulation of the operation cap 6 by the thumb.
[0018] Further, the joystick is suitable for the operation needs of light servo mechanisms.
[0019] The working principle of the present invention is:
[0020] Operate on the operation cap 6 with the thumb, transmit the corresponding command to the Hall sensor 2, and act on the circuit board 3 through the magnetic field ins...
