Membrane 1×4 Keypad


Membrane 1×4 Keypad



This 1 x 4 matrix keypad (also known as a membrane keypad) has 4 buttons arranged in a 1 x 4 pattern. Since this keypad has only one row of 4 outputs, no special code or libraries are required to add this to your project, simply treat this as 4 standard buttons.

The connector uses a standard pitch (0.100” / 2.54mm) and will fit into our Breakaway Headers. Want to plug it into a solderless breadboard? These Equal Length Headers will help.


  • Standard breadboard pitch (0.100” / 2.54mm)
  • Requires 4 digital inputs
  • Adhesive backing
  • Simple to implement, no special code required
