Abstract
Clickpad structures may be attached to surfaces of an information handling system using material stacks comprising an elastic material, such as a sponge, which can preload a force on the clickpad surface. The preloaded force reduces a gap between the clickpad switch and contact point, which reduces instability, rattling, and other negative experiences with the clickpad surface experienced by a user. According to an embodiment, an input device for an information handling system includes a clickpad surface having a first side configured to receive user input and a second side opposite the first side; a first coupling stack comprising a first elastic material with a first thickness; and a second coupling stack comprising a second elastic material with a second thickness, wherein each of the coupling stacks is attached to the clickpad surface and a surface of the information handling system by adhesives.
