Keypad Switches

Keypad switches are electronic switches that use a matrix of buttons or keys to input data or control functions. They are commonly used in consumer electronics, industrial control systems, and medical devices.

Keypad switches typically consist of a set of buttons or keys arranged in a matrix pattern, which are connected to a printed circuit board (PCB). When a button or key is pressed, it completes a circuit on the PCB, sending a signal to a microcontroller or other control system.

Keypad switches come in different configurations, including membrane keypads, elastomeric keypads, and mechanical keypads. Membrane keypads use a thin, flexible membrane to activate the switch, while elastomeric keypads use a rubber or silicone dome to provide tactile feedback. Mechanical keypads use a physical switch mechanism, similar to a keyboard.
