An electronic device is disclosed. The electronic device may include a sealing element between a protective cover and a housing of the electronic device. The sealing element may provide a seal between the protective cover and the enclosure, as well as monitor or detect a force to the protective cover. Also, one or more support members may surround the sealing element to provide protection against a material (such as liquid) entering an opening between the protective cover and the enclosure. Alternatively, or in combination, the sealing element may include several openings, each of which may include a restraining element to limit movement of the sealing element. Also, a blocking element may be placed at or near an edge of the enclosure to provide additional reinforcement if the sealing element is laterally displaced. The blocking element may include an operational component of the electronic device, such as an antenna.
