1×4 Flexible Membrane Keypad 4 Keys

The 1×4 Flexible Membrane Keypad gives your project four slim, tactile input keys on a single thin, flexible strip. Its soft membrane construction and self-adhesive backing let you stick it straight onto an enclosure, control panel, or project box without drilling or screws, so it is perfect for adding simple input to a clean, low-profile build.

The keypad connects through a 5-pin, 2.54mm pitch female connector, which plugs directly onto header pins or connects with jumper wires to Arduino, ESP32, Raspberry Pi, or any other microcontroller. Because it needs only a handful of pins, wiring is quick and easy, and the keys can be read with simple digital inputs. The thin membrane design is lightweight and rated for around one million presses, so it holds up to long-term use.

Use it for menu navigation, password entry, mode selection, or device control panels. Whether you are a beginner learning to read button inputs or a maker adding a compact control strip to a custom enclosure, this keypad is an easy, affordable input solution.
