Keys And Keypads

Key and keypad components provide input interfaces for robotics, automation, and embedded projects. Expect mechanical switches and matching keycaps, standalone keypads, and input controllers. Many options are designed for easy integration on small boards, with breakout or carrier boards to simplify wiring to microcontrollers and single-board computers. Wireless and wired variants cover compact control needs, including keyboards with built-in navigation controls for a tidy, single-device solution.

Attributes include compatibility with standard switch footprints and keycap profiles, the actuation feel and noise, and durability over many cycles. Products range from fully assembled keypads to modular components that mix and match. Differences appear in footprint and layout, connector types, and mounting options, supporting simple user input panels or more complex multi-button interfaces for sensors, test rigs, and automation panels.
