1 x 4 Matrix Membrane Keypad

The ribbon cable is nice and long, making it easy to route to my Arduino board. Each button press registers cleanly, and it's impressively thin against my project box.

The adhesive backing stuck perfectly to my enclosure on the first try, and the flat ribbon cable made wiring it into my project a breeze. It’s so thin I barely noticed it was there, yet the keys respond with a satisfying click every time.

I needed a simple 4-button interface for a drawer lock project and the 72mm ribbon cable was the perfect length to reach my control board. The ultra-thin design and adhesive backing made mounting it flush on the inside of the drawer a breeze.
