KEY DESIGNS

These are the first designs for the keys and the bases. These designs turned out to work better than my updated ones! Unfortunately, they were bulky and did not have a built in method to be fit together in a larger package. This prompted a redesign.

SECOND ATTEMPTS

Here are the aforementioned redesigns! These certainly look impressive, and did solve some issues. The pegs on the key base provided a good way to fit the sensor circuit boards on, and the screw holes provided a reasonable method of securing the base onto a larger package. Unfortunately, the point at which the key meets the base does not have the proper clearance, and they fit too tightly to allow free movement. A spring pin is meant to be inserted to secure the key to the base, and this only exacerbates the issue, making the key more difficult to move.
