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.
