Keypad & housing design for remote control

Keypads are input devices that consist of a set of buttons or keys arranged in a grid-like pattern. Each button typically corresponds to a specific character, number, or function. Keypads are commonly used for data entry, control interfaces, and security systems. They can be found on various devices such as telephones, calculators, remote controls, ATMs, and security access panels. Users interact with keypads by pressing the appropriate buttons to input data or execute commands.
