This DC 12V 4×1 Key Matrix Membrane Switch Keypad 107x20x0.8mm is a high-quality product at very low cost for your application needs.
This 4-button keypad 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.
The Keypad 1×4 features a total of 4 buttons in Matrix form. This is a membrane keypad with no moving parts. A female 5-pin berg connector is required for interfacing it with your microcontroller circuits.
Features :
- Ultra-thin design & adhesive backing provides easy integration to any project
- Excellent price-performance ratio
- Easy communication with any microcontroller
- 5 pins 2.54mm pitch connector, 4×1 type 4 keys.
- The sticker can peel off for adhesive mounting.
- Used widely in industrial and home electronic equipment, instrument, etc.
- This allows a microcontroller to ‘scan’ the 5 output pins to see which of the 4 buttons is being pressed.
