Key apparatus
A key apparatus includes a housing with an opening, a printed circuit board (PCB) received in the housing, and a key mechanism. The key mechanism includes an electrode portion and a conducting portion sandwiched between the electrode portion and the PCB. The electrode portion is electrically connected to the PCB. The conducting portion is apart from the PCB. While the conducting portion connects with the connecting region, the electrode portion and the connecting region form a capacitor. The PCB generates different control signals based on different capacitances of the formed capacitors.
