I sit for my grand-daughter and she loves turning the lights off and on. I remembered having a device that went on the light switchplate that allowed 'little ones' the opportunity to turn the lights on and off for themselves.

So, I modeled a faceplate that has an actuator that flips the light switch by pulling a cord. One cord to turn on the lights and the other cord to turn them off. NOTE: Files are in inches NOT mm.

Material list
1 - 48" 325 Paracord Available at Hobby Lobby in various colors. I used purple.

2 - wooden beads 3/4" or 20mm in diameter with through holes. I like different color beads for on and off. For those devoted to only using what you can print, I have included a file for printing beads. If you do decide to print the beads, it is highly suggested that you use a raft.

2 - 6-32 1" flat head screws. Longer screws will probably be needed to attach the faceplate. The ones supplied with a switchplate are usually very short and will most likely not work for you.

Instructions
1) Download and 3D print the pieces. I printed in ABS for strength.
2) Cut 48" of Paracord. Your length may vary as necessary. I singed the ends using a torch to prevent fraying.
3) Using 9/64" drill bit, drill through the mounting holes of the faceplate. This will insure easier installation.
4) Using a 13/64" drill bit, drill the larger hole of the actuator. This will facilitate a smoother operation of the actuator.. Use a 5/32" drill for the smaller holes.
5) (optional) Using #400 sandpaper, sand the parts to smoothness. Wash with water after sanding. For shininess, give the parts an acetone vapor bath.
6) Fold the cord in half to determine the middle. Feed the cord through the actuator about 3 inches from the center as pictured.
7) Assemble the actuator to the faceplate as pictured draping the cord over the top track. The longer portion of the cord goes over the top track.
8) Remove the existing screws on the switchplate. Using the new screws, attach the faceplate and actuator being careful not to pinch the cord. Test to make sure the light goes on and off when pulling the cords.
9) After you are satisfied with the operation, thread the beads on the cords. Determine the best length for the cords and cut the cords off and tie a knot.

Use a raft for only the beads if printing.
