ABSTRACT:
A fluid isolation and dispersion system which includes one or more sealing devices to minimize the chance of fluid damage to electronic components. The system includes seals between keys of a keypad and aperture walls in a cover member through which the keys protrude, and a number of chambers around the keys for trapping fluid that has passed through any one of the seals. The chambers are defined by chamber walls linking the aperture walls, and a gasket below the chamber walls. The system may additionally include a channel formed between a periphery wall around the aperture walls and a flexible periphery wall around the gasket for diverting fluid that has passed by any one of the chamber walls, and a spout on one side of the gasket for discharging the fluid from the channel.
