Description
A 4×3 Membrane Keypad is a type of input device that consists of 4 rows and 3 columns of button switches. The buttons are typically covered by a flexible, conductive membrane that provides a soft and durable surface for the user to press. The buttons make contact with the underlying circuit when they are pressed, allowing the user to input commands or data. The 4×3 configuration allows for 12 buttons to be present on the keypad, which can be used for a variety of functions, such as entering numbers, navigation, and control. Membrane keypads are commonly used in consumer electronics, appliances, and industrial equipment due to their low cost, durability, and ease of integration.
