Abstract
Disclosed herein is a stack-up for an input device. The stack-up may include a flexible substrate having a switch and a light source. The switch has at least two contacts that are bridged in response to actuation of a dome that is positioned above the switch. The flexible substrate includes a signal trace for detecting the actuation of the dome and a power trace for providing power to the light source.

A stack-up for an input device, the stack-up comprising:
- a flexible substrate;
- a switch having at least two contacts coupled to the substrate;
- and
- a dome positioned above the switch;
- wherein deflection of dome bridges the at least two contacts of the switch and causes the switch to conduct a signal along a power trace formed on the substrate.

A stack-up for an input device, the stack-up comprising:
- a flexible substrate having a signal trace formed thereon;
- a switch having at least two concentric contacts coupled to the substrate;
- and
- a dome positioned above the switch, the dome having a conductive material integrated with a bottom surface of the dome, the conductive material adapted to bridge the at least two contacts of the switch in response to actuation of the dome.
