Abstract: This application is directed to system, devices, and methods of keyboard key switches that facilitate electrical connections to specialized keycaps. In some embodiments, a serial connection (e.g., USB or any serial protocol) can be created and maintained between a key switch of the inventive subject matter and a specialized keycap that couples with a top portion of the key switch's plunger. Key switches of the inventive subject matter incorporate spring probes to create electrical connections between a printed circuit board disposed below the key switches and the top portions of the key switches' plungers. Thus, different regions of a key switch's plunger can feature different conductive regions, which facilitates creating electrical connections between a PCB and a specialized keycap.

Abstract: This application is directed to keycaps for use in association with key switches that facilitate the creation of custom keyboards. Mechanical keyboards feature key switches having standardized top portions that make it possible to fit a wide variety of different keycaps thereon. Embodiments of the inventive subject matter include specialized, electronic keycaps that introduce different functionalities to improve keyboard customizability. For example, in some embodiments, keycaps can include haptic feedback mechanisms, while in other embodiments keycaps can include a display screen.
