1×4 Key Matrix Membrane Switch Keypad

DC 12V 1×4 Matrix Keypad is a Membrane Type 4 button keypad. It has 4 keys, and since every key has its own wire line, no matrix code is required – just treat these like every day switches. The membrane is soft and has a removable paper backing to expose a strong adhesive so you can stick this on an enclosure and feed the cable through a slot.

It provides a useful human interface component for microcontroller projects. Convenient adhesive backing provides a simple way to mount the keypad in a variety of applications.

Features :

• Ultra-thin design & adhesive backing provides easy integration to any project
• Excellent price-performance ratio
• Easy communication with any microcontroller
• This allows a microcontroller to ‘scan’ the 5 output pins to see which of the 4 buttons is being pressed.
