4×4 Membrane Keypad

Be it a control panel interface or a cell phone input method, keypads are a popular way of passing data and commands to an electronic system for processing.

The 4×4 membrane keypad features an ultra-thin matrix of soft-to-touch switches arranged in 4 rows and 4 columns, and hence its name. Most will come with an adhesive backing for easy attachment in a variety of applications. It provides an intuitive connection of 16 input possibilities via only 8 pins.
