Abstract
A spring coupled to a multi-layered flex membrane is described. In one embodiment, the spring may be a layer coupled to the top layer of a key switch membrane. In another embodiment, the spring may be coupled to the key switch between a top layer and a spacer layer. The spring or spring layer may increase the resiliency of the key switch membrane to prevent the flex membrane from deforming.
