Abstract
Keyboards include mechanisms that prevent and/or alleviate contaminant ingress. In some embodiments, a keyboard assembly includes a substrate, a key cap, a movement mechanism moveably coupling the key cap to the substrate, and a guard structure coupled to the key cap operable to direct contaminants away from the movement mechanism. In other embodiments, a keyboard includes a base; a web that defines apertures; keys moveably coupled to the base within the apertures; and a gasket coupled to the keys, the gasket fixed between the web and the base, operable to block passage of contaminants into the apertures.
