Putting HCS Voyager in/out of cap sewing mode: When the cap driver is installed, it presses in the large black switch shown above,
which in turn presses the thin, copper colored strip of metal above it, which in turn presses in the small white tab that can be seen
just below the red arrow.  When this black plunger switch is released, as shown in this animation, the copper strip should naturally hang downwards, and the
white tab should follow it downwards.
