Layers: It's made up of several thin layers of flexible materials, including a top layer with the key labels (like numbers or letters), a spacer layer, and a bottom layer with conductive traces (like tiny wires).

2. How it Works: When you press a key, the top layer pushes down through the spacer layer and makes contact with the conductive traces on the bottom layer. This completes an electrical circuit, telling the device which key was pressed.
