Keypad - Sealed Membrane Switches

Repacement: None. We don't currently have a replacement for this keypad. This page is for reference only.

This is a specialized adhesive keypad with 27 buttons and a 13 pin output in matrix form. This allows a microcontroller to 'scan' the 13 output pins to see which of the 27 buttons is being pressed. Keypad is super thin with an adhesive backing.

  • 3.7" x 1.85"

  • For an enclosure I've found that the Hammond 1593-TBK is a near perfect match.
    Information on that line of enclosures is here: http://www.hammondmfg.com/dwg8.htm These boxes are designed for hand held solutions, have rounded edges, recessed top, and some models have battery compartments.

  • Any idea when this will be back in stock? It looks perfect for a project that I am working on. Thanks.

  • Does anyone know the max current ratings of this Keypad?

  • a Breakout Board please!!!!!!!!!!!!!!

  • This is like a virtual keyboard, only physical(obviously).

  • Wish this fit onto the sparkfun project enclosure.
    It almost fits

  • These are extremely thin and flexible, you don't really need a specifically designed enclose, just a flat surface to stick it on.
    As an alternative you can peel these things off the front of a lot of old microwaves. Although, this one looks much cooler. (Having buttons like "popcorn" and "defrost" on a robotics project looks kind of silly)

  • Do you have an enclosure in mind for this?
