The 4-Key Membrane Keypad offers a simple, low-profile way to add numeric input to your project, with individual button connections and an adhesive backing for easy installation in enclosures and control panels. Punch in your secret key into this numeric membrane keypad. This keypad has 4 buttons, and since every key has its own wire line, no matrix code is required - just treat these like every day switches. The membrane is soft and has a removable paper backing to expose a strong adhesive so you can stick this on an enclosure and feed the cable through a slot. Its a simple keypad but that's why we like it. We include a 6-pin extra-long header strip so you can plug this into a breadboard with ease.
