    • 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.
    • 为了防止碎片进入圆顶和圆顶开关的触点之间的体积,圆顶可以包括通道,其提供可以通过空气排出的远程路径。 特别地,通道可以从穹顶延伸到已知是或预期不含污染物的电子设备内的位置(例如,设备的不包括与设备环境通信的任何接口的区域)。 通道可以由圆顶开关的部件定义,包括例如由柔性电路和薄膜层之间的间隔壁限定的通道。 通道可以包括用于通风球形开关的开口。 在一些实施例中,圆顶开关可以包括施加在通道中的开口上的保护膜。 可以选择保护膜以允许空气流过,但是防止污染物或颗粒到达通道开口。
