The invention discloses a photoelectric control integrated
input device switch module capable of generating twice touch click sounds, which comprises an upper cover, a central shaft active
assembly,
metal elastic sheets, a spring, optical elements,
small hole diaphragms, a
light emitting device, a light receiving device, a lower cover and a PCB. Two sides of a central key shaft are respectively provided with a
sound production mechanism and a control mechanism, the
sound production mechanism is located at one side of the central key shaft and comprises a convex part of an active sliding block and the
metal elastic sheet for generating a key click sound; and the control mechanism comprises a convex part of the central key shaft, the optical element, the
metal elastic sheet, a light baffling sheet whose edge is bent for a certain angle, and light emitting and receiving devices for controlling off or on of a light path. The module of the invention adopts an independent new click
sound generation structure, on and off of the switch are not influenced, convenience, diversity and stability of design are achieved, and diverse different click sound can be created.
