Classification: CPC G  H | IPC G  H

Claim 0:
1. An electronic device comprising:
a key having a switch and a movable key member that is configured to change a state of the switch when the key is pressed during a key press event;
key sensor circuitry;
a signal path that couples the key sensor circuitry to the switch of the key, wherein the key sensor circuitry is configured to detect the key press event based on a signal on the signal path;
a plurality of signal lines overlapping the key and forming capacitive touch sensor electrodes;
capacitive touch sensor circuitry coupled to the plurality of signal lines and configured to detect a touch input event at the key using the plurality of signal lines; and
a layer of material having a first side facing an exterior of the electronic device and having a second side opposite the first side and facing an interior of the electronic device, wherein the layer of material includes an opening that overlaps the key, and the plurality of signal lines forming the capacitive touch sensor electrodes include a signal line that overlaps the opening and that is formed from transparent material.
