The membrane keypad provides 4 keys on an 5-pin connector using a matrix system to detect which key has been pressed.
The matrix keypad is wired via a flexible ribbon to an 8 pin header socket.
The keypad can be stuck to a hard surface using the sticky pad provided to provide a hard backing to the keypad - making it easier to press and use the keys.
Pressing Key1 will make a close contact between pin 5 and pin 3
Pressing Key2 will make a close contact between pin 5 and pin 4
Pressing Key3 will make a close contact between pin 5 and pin 1
Pressing Key4 will make a close contact between pin 5 and pin 2
Perfect for adding user input to your projects or as a replacement to worn keypads.
