The 4×4 Matrix 16 Key Membrane Switch Keypad is a flat, thin, flexible keypad with 16 soft-touch keys arranged in a 4 row by 4 column matrix, featuring a self-adherence backing that sticks directly to any flat panel, enclosure wall, or project box surface — making it the right choice for clean, professional-looking installations where the keypad needs to sit flush on a surface rather than standing out on a separate module board. This membrane keypad module uses the same 8-pin row-and-column matrix interface as a rigid keypad, so it connects to Arduino and other microcontrollers identically.
The membrane keypad price-accessible soft-touch surface registers key presses with a light finger touch and a fast 1ms rebound time, meaning the membrane returns to its rest state within one millisecond after release — fast enough that rapid sequential key presses are detected cleanly without keys sticking or registering multiple times from a single press. The 16 key membrane switch keypad’s self-adhesive mount allows permanent installation inside a custom enclosure without any screws, brackets, or additional hardware.
The 4×4 matrix membrane keypad pinout follows the standard row-column convention, making it fully compatible with the Arduino Keypad.h library used for the rigid 4×4 keypad — no code changes needed when switching between the two variants. Available from StemVolt, This membrane switch is ideal for panel-mount Arduino enclosure input builds.
