CA 2732051

A keyboard dome stiffener assembly includes a circuit board having a plurality of dome pads that each define a venting aperture, a dome sheet disposed over the circuit board, and a stiffener disposed beneath the circuit board that defines a plurality of cutouts corresponding to each venting aperture. The dome pads correspond to a key of an associated keyboard to be assembled with the keyboard dome stiffener assembly. The dome sheet forms an air space associated with each dome pad that is in fluid communication with the corresponding venting aperture. The cutouts of the stiffener provide an air cavity between the circuit board and the stiffener. Each air cavity is in fluid communication with an air space, and when one of the keyboard keys is depressed, some of the air in the air space travels between the air space of the keyboard to the corresponding air cavity.
