4*3 MATRIX KEYPAD

A Matrix keypad is a small compact input device that accepts user input and is processed by the microcontrollers. 4*3 matrix keypad has 12 keys connected in rows and columns. A female 7-pin berg connector is required for scanning the keypad and interfacing it with your microcontroller circuits.. When a key has been pressed the row and column make contact with each other, otherwise there is no communication between them. A microcontroller can scan7 output pins when a button is pressed down. And thus determine which of these 12 buttons pressed. This 4*3 MATRIX KEYPAD is mainly used in industrial and home electronics equipment, controls system,s etc.

This DC 12V 4×3 Matrix 12 keys Membrane Switch Keypad is designed as a high-quality soft-touch feeling button keypad with 100 million life-stroke lifespans and also offers good resistance to environmental conditions. This low-cost matrix keypad with 12 button keypad ensures a useful human interface component for microcontroller projects or for your application needs. Moreover, the thin and flexible adhesive backing provides a simple and easier way to mount the keypad in a wide variety of applications. And also this is a membrane keypad with no moving parts.
