| To prevent debris from entering the volume between a dome and contacts of a dome switch, a dome can include a channel providing a remote path through which air can be vented. In particular, the channel can extend from the dome to a location within an electronic device that is known to be or expected to be contaminant free (e.g., a region of the device that does not include any interfaces communicating with the device environment). The channel can be defined from components of the dome switch including, for example, as a channel bound by spacer walls between a flex circuit and a film layer. The channel can include an opening for venting the dome switch. In some embodiments, the dome switch can include a protective film applied over the opening in the channel. The protective film can be selected to allow air to flow through, but to prevent contaminants or particles from reaching the channel opening. | ||||||
