Step 6Add the Switch
This is the component that will automatically contract and expand the Flexinol as needed.
The setup for the switch (it will be calibrated later) is pretty straight forward.
First, cut a piece of Plexiglas about 1 - 1.2cm wide by 2.5-3cm long.
Next, drill a 5/8 " (or slightly larger then 9/16") Hole in the middle of one end and 3, 1/16" holes in the other end.
Now thread a bamboo skewer into the switch hole drilled in step 3, and cut all of the extra off one side, but leave 1-1.5cm sticking out the other side.
Next, attach the piece of Plexiglas to the bamboo skewer by putting the skewer through the large hole and threading the nut behind the Plexiglas on the skewer. Tighten the nut down so the Plexiglas will move stiffly.
