Zusammenfassung: | The disclosure relates to implementing different key types on a keypad or keyboard. The implementation can be enabled e.g. by an apparatus including a substrate (28) including a capacitive sensor element (29), the capacitive sensor element having a first electrode (24) forming a first capacitor with an object touching or coming into proximity of the first electrode, wherein the capacitive sensor element is configured to generate a first signal responsive to the object touching or coming into proximity of the capacitive sensor element, a first capacitor circuit coupled to at least the first electrode, and a dome (26) configured to complete, responsive to the dome being depressed, an electric circuit including at least the first capacitor and the first capacitor circuit to form a second capacitor circuit, wherein the second capacitor circuit is configured to generate a second signal. |
