A device includes a printed circuit board having a first surface and a
second surface. The printed circuit board defines an opening therethrough
from the first surface to the second surface and a circuit formed on the
first surface of the printed circuit board with no portion of the circuit
intersecting the opening. The second surface of the printed circuit board
at least partially bounds a first channel in fluid communication with the
opening. A method of venting includes displacing air within a cavity of a
switch by moving the air through one or more channels formed in a layer
defining cut-outs in fluid communication with the cavity. The air is
moved through an opening formed in a printed circuit board. The layer is
positioned at a first side of the printed circuit board. In addition, the
method includes moving the air through a venting channel positioned at a
second, opposite side of the printed circuit board and into the
surrounding environment.
