Abstract
Disclosed herein is an input device having variable make points. More specifically, the various embodiments described herein are directed to an input device having a key, a first button member and a second button member. A dielectric may be positioned between the first button member and the second button member. The key is also associated with a capacitive sensor that is configured to determine a change in capacitance as a distance between the first button member and the second button member changes.
