An apparatus, system, and method provide electrostatic discharge (ESD) protection in electronic devices by guiding electrostatic charges to a ground through ESD channels within electrical insulation sheet. The ESD channels are positioned within the electrical insulation sheet to provide electrical paths to ground having a lower impedance than electrical paths to protected areas covered by the electrical insulation sheet. Accordingly, an ESD follows the path of least resistance safely to ground rather than to a critical component within the electronic device. In the exemplary embodiment, the ESD channels are openings in a dome contact layer of a keypad where the openings are positioned over one or more ground areas of a printed circuit board (PCB) and the insulting material of the dome contact layer covers areas of the PCB that are protected from ESD. By implementing dedicated GPIO lines, grounded metal domes cover the signal pads in the target discharge area to protected the GPIO lines from ESD. Device components are protected from ESD without additional ports or insulation.
