Ceramic insert control mechanism

A control mechanism for an electronic device, the control mechanism comprising:

• a cover glass having an aperture defined therein, the aperture extending from an interior of the electronic device to an exterior of the electronic device;
• an actuator positioned within the electronic device, proximate the aperture;
• and
• a control member positioned within the aperture and coupled to the actuator, the control member comprising:
• a ceramic insert having a contact surface exposed to the exterior of the cover glass, wherein the control member is operable to actuate the actuator in response to a force on the contact surface;
• and
• a bearing member molded about the ceramic insert and positioned within the aperture between the insert and the cover glass, the bearing member having a hardness less than that of the ceramic insert and less than that of the cover glass.
