The main control circuit board 1 is provided with a turntable 4, the edge of which is provided with gear teeth 5. An independent handwheel 6 is provided on one side of the gear teeth 5. The independent handwheel 6 engages with the gear teeth 5 of the turntable 4. The turntable 4 can be driven to rotate by operating the independent handwheel 6. A key circuit board 7 is fixed to the turntable 4. The key circuit board 7 is connected to the main control circuit board 1 via a wire. Two groups of function keys 8 are fixed to the key circuit board 7 via a pressure plate 12. The two groups of function keys 8 are driven by the turntable 4 to alternately correspond to the position of the function keycaps 2. The upper end surface of the function key 8 is provided with a key mark 9, which can be seen through the transparent function keycap 2. To create a lighting atmosphere for the transparent function keycaps 2, a light source (not shown) is installed on the key circuit board 7. This not only acts as an ambient light but also makes the key labels 9 clearer. The bottom of the turntable 4 is provided with a stopper protrusion 10, and the main control circuit board 1 or the game controller housing is provided with a corresponding stopper notch 11. When the stopper protrusion 10 abuts the ends of the stopper notch 11, the switch is in place. During operation, the function keycap 2 can be switched to which group of function keys it corresponds to, depending on the game console or game scene.

[0026] Example 2: Figures 5 to 8As shown, this embodiment adopts a manual switch-type switching adjustment method. A switching mechanism for a game controller function key includes a main control circuit board 1 and a keycap assembly.
