BUTTON INTEGRATION FOR AN ELECTRONIC DEVICE

摘要

This application relates to various button related embodiments for use with a portable electronic device. In some embodiments, a snap clip can be integrated with a button bracket to save space where two separate brackets would take up too much space in the portable electronic device. In other embodiments, a tactile switch can be waterproofed by welding a polymeric layer atop a tactile switch assembly. In this way water can be prevented from contacting moisture sensitive components of the tactile switch assembly. The weld joining the polymeric layer to the tactile switch can include at least one gap to trapped gas surrounding the tactile switch assembly to enter and exit during heat excursions caused by various operating and/or assembly operations.

主权项

1. A button assembly, comprising:
a switch body; a tactile switch coupled with a first surface of the switch body; a polymeric film extending over and surrounding the tactile switch, wherein the polymeric film is joined to the switch body by a weld, the weld defining a plurality of gaps that allow air to pass into and out of an interior volume defined by the switch body and the polymeric film without allowing liquids to enter the interior volume through a joint formed by the weld; and a protective layer coupled to a second surface of the switch body, the second surface being positioned opposite the first surface, wherein the protective layer prevents ingress of liquids into the switch body through a plurality of tooling pin holes defined by the second surface of the switch body.
