Supplies
For this Instructable, you will need the following items:
- One (1) Push Button
- One (1) 3.5 mm male jack
- Long wire
- One (1) roller switch
- Non-slip mat
Take the Long Wire, Separate the Black and Red Wire at One End for About 2 Cm
Clamp the Red Wire About 1cm Deep at the Third Notch (1.0mm)
And Then Pull to Strip the Insulation From the Wire.
If you are using a strip gun, clamp the wire and pull the trigger quickly.
Do the Same for the Black Wire, Leaving Slightly More Insulation on the Black Wire (strip the Red Wire a Bit More).
Unscrew Earphone Jack
To unscrew, grip the pin with one hand and the shell in another, then turn in opposite directions
Thread the Stripped End of the Wire Thru the Shell
Pass BLACK Wire Through the Hole in the Shorter Leg
Wrap the Wire Around the Leg
Pass RED Wire Through Taller Leg
Wrap the Wire Around the Leg
Use the Tools to Make Sure There Are No Stray Strands of Wire, and Pull Lightly to Test If Secure
Solder BLACK Wire
Solder RED Wire
Visually Check That There Are No Stray Wires, Then Screw the Shell Back On
Take the Other End of the Long Wire, Strip the RED and the BLACK Wire About 1 Cm.
Now Take the Roller Switch. Using the Wire That You Just Stripped; Pass RED Wire Through Hole in the Bottom Leg
Wrap the Wire Around the Hole
Pass BLACK Wire Through Hole in the Lower Leg
Wrap the Wire Around the Hole
Solder the Two Joints
Then Bend the Metal Switch to Around This Shape
Take the Push Button Switch. Remove 4 Screws to Open the Cover
Cut Away the Wires Attaching the LEDs to the Plastic Body. Remove Switch From Slot by Pulling Vertically Up
Cut a V-shaped Slot As Shown in Picture
Now Place the Switch Into the Hole in the Middle.
Be sure that roller is facing away from the springs.
Drill 4 Holes, They Should Be Aligned to the Roller Switch’s Holes (see 3rd Picture)
Use 2 Zip Tie to Secure the Switch. Trim Off the Excess of the Zip Tie
Wrap the Cord Around the Base As Shown in the Picture
Use the zip tie to tie off the wires to one of the screw posts. This helps take the stress from any pulling of the cable by the user.
Replace Switch Cover, Making Sure the Wire Goes Out of the Notch That You Cut
Close Cover & Replace 4 Screws.
After you replace the screws, check to make sure the switch is NOT already depressed (listen for the click).
If it is, dismantle it, bend the metal switch a bit more, and try again.
Use Double Sided Tape and Stick the Non-stick Mat.
This will keep the switch in place when a special needs child uses your work!
