4X4 16 Matrix Membrane Keypad Switch-16 Key
There are a total of four rows and four columns of keys in the 4x4 matrix layout of the keypad. In all, 16 keys are present. Because it makes keys accessible in a logical and orderly manner, this structure is ideal for applications that demand a set of fixed input possibilities. The keys are operated by membrane switch technology, which senses when a key is pressed and completes a circuit. This technology can be used at home or in the office because it guarantees a quiet and soft keypress. The keyboard's materials are strong and resistant to deterioration. Because it is lightweight and manageable despite its durability, it is perfect for incorporating into a range of products and projects. The keypad is made to fit into electrical circuits and other devices with ease. The flat, flexible ribbon cable that is usually included with it makes setup and connection simple.
