Button assembly and controller including the same

A controller, comprising:

• a button assembly, including:
• a pedestal, a middle of the pedestal having an accommodating groove penetrating upward through a top surface of the middle of the pedestal, two opposite sides of the pedestal protruding oppositely outward to form a lower active portion and a lower pivot portion;
• a pressure sensor module mounted in the accommodating groove of the pedestal;
• and
• a key cap covered on the pressure sensor module, a bottom surface of the key cap having a contact portion contacting with the pressure sensor module, two opposite sides of the key cap protruding oppositely outward to form an upper active portion and an upper pivot portion, respectively, the upper active portion being movably fastened to the lower active portion to form a movable active assembly, the upper pivot portion and the lower pivot portion being pivotally fastened with each other to form a pivot assembly, in processes of pressing and releasing the key cap, the upper pivot portion rotating pivoting the lower pivot portion, the upper active portion of the active assembly moving downward and upward with respect to the lower active portion;
• a fastening frame mounted under the button assembly;
• a circuit board mounted under the fastening frame and the button assembly;
• a casing surrounding upward the circuit board, the fastening frame and the button assembly;
• an outer shell, the casing, the circuit board, the fastening frame and the button assembly being disposed in the outer shell;
• and
• a top cover assembled on the casing, and covering the button assembly, the fastening frame, the circuit board, the casing and the outer shell, a middle of the top cover opening an opening vertically penetrating through the top cover, the key cap being exposed outside from the opening.

A button assembly adapted for being mounted in a controller, comprising:

• a pedestal, two opposite sides of the pedestal protruding oppositely outward to form a lower active portion and a lower pivot portion;
• a pressure sensor module mounted in the pedestal, a top of the pressure sensor module having a soft material sensor, the soft material sensor having an elasticity;
• and
• a key cap covered on the pressure sensor module, a bottom surface of the key cap having a contact portion contacting with the pressure sensor module, two opposite sides of the key cap protruding oppositely outward to form an upper active portion and an upper pivot portion, respectively, the upper active portion being movable fastened to the lower active portion to form a movable active assembly, the upper pivot portion and the lower pivot portion being pivotally fastened with each other to form a pivot assembly, in processes of pressing and releasing the key cap, the upper pivot portion rotating pivoting the lower pivot portion, the upper active portion of the active assembly moving downward and upward with respect to the lower active portion;
• wherein when the key cap is pressed, the soft material sensor shows a sunken status, the first protruding block passes through the active hole and the upper active portion moves downward along the first protruding block to make the upper active portion move downward, at the same time, the upper pivot portion rotates in the lower pivot portion to a pressing portion, when the key cap is released, the soft material sensor will rebound upward to return to an original status so as to push upward the contact portion and make the upper active portion move upward along the first protruding block, the upper active portion is movably fastened to the lower active portion, so the upper active portion will generate an upward resilience force to make the pressed upper active portion of the key cap bounce upward to return to an original position, at the same time, the upper pivot portion rotates to the original portion.
