This DC 12V 4×3 Matrix 12 keys Membrane Switch Keypad is high-quality soft touch feeling button keypad with 100 million life-stroke lifespans and good resistance to environmental conditions. RoboticsBD
This DC 12V 4×3 Key Matrix Membrane Switch Keypad is a high-quality product at very low cost for your application needs. Punch in your secret key into this numeric matrix keypad. This keypad has 12 buttons, arranged in a telephone-line 3×4 grid. It’s made of a thin, flexible membrane material with an adhesive backing (just remove the paper) so you can attach it to nearly anything. The keys are connected into a matrix, so you only need 7 microcontroller pins (3-columns and 4-rows) to scan through the pad. RoboticsBD
