A venting system for a keyboard assembly is disclosed. A keyboard assembly including a printed circuit board defining a set of apertures, and a group of switch housings coupled to the printed circuit board. Each switch housing of the group of switch housings may define a switch opening positioned above one of the set of apertures of the printed circuit board. The keyboard assembly may also include a shield defining at least one channel of a venting system formed below the printed circuit board. The at least one channel may be in fluid communication with at least one aperture, and at least one of the switch openings positioned above the at least one aperture.
