A sealed dome switch assembly is provided to allow air to flow between the interior and the exterior of the dome switch during the collapse and recovery of the resilient dome shell (330). The sealed dome switch assembly comprises at least one vent (340) leading between the interior space (320) and the exterior space (322) of the sealed dome switch, wherein the vent (340) is covered by a membrane (344) that is permeable to air and resilient to liquid (e.g. water) and small particles (e.g. dirt). A vent may also be used to network the interiors of a plurality of sealed dome switches to at least one exterior entranceway that is covered by the membrane. |
