CERAMIC INSERT CONTROL MECHANISM

摘要

A control mechanism for an electronic device comprises a cover glass having an aperture defined therein. The aperture extends from an interior to an exterior of the device. A control member is positioned within the aperture, coupled to an actuator. The control member comprises a ceramic insert having a contact surface exposed to the exterior of the housing, operable to actuate the actuator in response to a force on the contact surface. A bearing member is molded about the insert. The bearing member has a hardness less than that of the ceramic insert, and less than that of the cover glass.
