Abstract: A computer keyboard assembly includes a bottom module connected separably to a top module. The bottom module has a top wall formed with through holes registered respectively with key caps mounted movably on the top module, a wiring board provided with electrical contacts, an actuating unit disposed on the wiring board and having upright biasing members, each extending upwardly through a corresponding through hole and having an actuator contacting electrically a corresponding electrical contact as a result of movement of a corresponding key cap from a normal position to a depressed position, and a keyboard controller for interpreting a mode identification signal from a mode-determining unit of the top module so as to output an identification code corresponding to the mode identification signal.

Abstract: A modular computer keyboard assembly that separates keyboard components into two groups. One group of components becomes a detachable module, while the other group stays as the base module. Depending on applications, the detachable module can be further broken into more sub-modules. Keyboards manufactured following the method proposed by present invention are modular in nature, and are conducive to reducing the costs for keyboard services and exchanges, costs for curing future environmental hazards and costs for fitting suitable user keycaps for swapping among different languages and computer applications.

Abstract: A new kind of splash-resistant modular keyboard for computers that separates keyboard components into two groups. One group of components becomes a detachable and user-serviceable keycap module, while the other group stays as the base module. The detachable module contains essentially the keycap portion that contributes to more malfunctioning of present day keyboard. The base module has a bay that receives the detachable keycap module, and contains the electrical circuitry membrane and PCB that has longer durability than the keycap portion. Drain holes at lower end of the bay will allow liquid spillage, or when using water/solution to clean the bay, to flow out of the bay. Depending on applications, the detachable keycap module can be further broken into more sub-modules.
