1×4 Key Matrix Switch Keypad

A Matrix keypad is defined as a small compact input device that accepts user input and is processed by the microcontrollers. These keys are arranged as rows and columns. This DC 12V 1×4 Key Matrix Membrane Switch Keypad is designed as a high-quality product at an affordable rate for various applications. 1*4 matrix keypad designed as a non-encoded keypad consisting of 4keys in parallel with a built-in pushbutton. This 1*4 matrix keypad is designed as a membrane keypad with no moving parts. Hence, an additional female 5-pin berg connector is required for interfacing it with your microcontroller circuits.

It provides a useful human interface component for microcontrollers and interfaced easily in various projects. Moreover, the Convenient adhesive backing provides a simpler and easiest way to mount the keypad in a wide range of applications. This matrix Keypad 1×4 features a total of 4 buttons in Matrix form.  This 4-button keypad functions as a useful human interface component for various microcontroller projects. Moreover, the Convenient adhesive backing provides a simple and easiest way to mount the keypad in a variety of applications. And also allows the microcontroller to ‘scan’ the 5 output pins to see which of the 4 buttons is being pressed.
