An electronic eyewear device having temples that are lightweight, aesthetically pleasant, and include thermal management. The temples each have a thermally conductive stiffener with a non-thermally conductive overmolded material forming a window. The window in each temple exposes interior components, such the stiffener to ambient air, and allows heat generated by electronic components to be released to ambient air to cool the components through convection. The windows also allow the stiffeners to be coupled to tooling and are easily overmolded. The windows provide both an aesthetic feature and a functional feature.

A button-switch assembly provides a preloaded force design with an enhanced tactile feel while also providing a non-wobbly (stabilized) configuration and water/dust protection functions. Features of the button-switch assembly include excellent tactile feel through a stack up of a soft rubber layer of a deflection web and a hard PET film shim layer, a consistent pre-loaded push force through use of an angled deflection web, a button flange that minimizes rotation of the button while providing a consistent tactile feel even when the edge of the button is depressed, double sided sealing adhesive layers that seal off the opening in the housing for accepting the button to prevent water/dust from entering the opening, and gluing the button to the rubber deflection web in variable thicknesses to provide a stable tension force to minimize wobble of the button when depressed.
