Abstract:
A key mechanism (22) includes a key body (222), a resilient metal sheet (226), a circuit board (26). The circuit board (26) is placed between the key body (222) and the resilient metal sheet (226). The circuit board (26) includes a first surface (2622) facing the key body (222) and a second surface (2624) facing the resilient metal sheet (226). The first surface (2622) has a number of ground points connecting to the key body (222). The second surface (2624) has a switch unit corresponding to the resilient metal sheet (226).
