DIY On-Off Switch
Intro: DIY On-Off Switch
Simple idea which dosen't require special tools or skills to make it. This perfect to use with LED diodes. I'm going to built this switch into an upcoming project so if you interested in click on the follow button ;)
Materials:
- plywood or solid wood or hardwood
- thin wood (perhaps veneer or thin plywood)
- small screw
- solder tab or any electrically conductive metal
- rod or dowel
- CA glue
Tools:
- sandpaper or belt sander
- scissors
- saw
- drill
That's it! (if i missed something please let me know)
STEP 1: Watch the Video
Detailed video about how I made this project!
STEP 2: #1 - Cutting
I made two small blocks from plywood (solid is also usable) then I cut off a nearly 1"/2,5cm long piece from a 0,5"/12,5cm inch rod
I gave a quick sand to every edge and side to make the wood blocks nearly equal wide
STEP 3: #2 - Making the Base
I used CA glue to stick the blocks to a thin piece of veneer
Try to make the blocks parallel to avoid the unnecessary sanding
I did the same to the opposite side
STEP 4: #3 - Construct the Knob
I marked the center of the rod piece with an awl, this is going to be the knob for the switch
I drilled a matching size hole for the screw head
I fixed it with CA glue and tried to do my best to make it straight
I put more glue onto it just in case
STEP 5: #4 - Shaping
I sanded down the sides with a belt sander but the hole project can be made with only handtools and drill
To speed up the shaping process I cut off the most of the material with scissors
STEP 6: #5 - Awl and Hole
Take the awl again and mark the center on the top and drill a slightly smaller hole than the screw
STEP 7: #6 - Metal
This two tiny metal pieces are called for solder tab, I bent one end but any electrically conductive metal can be used
I used CA glue again to stick the metal pieces to the wood
I glued one to the bottom of the empty space and the other to the top, the key is to leave space between them
I wanted to leave only one side open so I glued another piece of veneer to the third side
STEP 8: #7 - Final Sanding and Shaping
There is nothing left just to sand it down and put the knob into it and it's ready to use
STEP 9: The End
I made a simple circuit to show you how this switch works (check it out on the video that's much more visible)
I connected a 3.6V battery and a rgb LED diode to the switch with alligator wires
Just turn the knob clockwise!
How this works? When you turn the knob it pushes the two metal pieces together which closes the circuit
Thanks for hanging with me

As always thanks for your support

Suggest you get a drill press for a Dremel tool instead of drilling into your hands...

Or at least use pliers.
I see this behavior in so many instructables, just not good. And yes, four fingers are pointing back at myself. - Glad to report, there are four ;)
Maybe someone could do some basic safety instructable!
I'm not talking about the "always wear safety glasses when holding a hammer" b.s. More like: use knifes and chisels in a way that the applied force doesn't point to a body part.
Any Pro here who wouldn't mind to share some this-is-how-to-hold-this-tool training?

I would suggest using a pair of plain old slip joint pliers or adjustable jaw pliers, (commonly called Channelock pliers, after the name of the maker) to give you some space between the drill bit and your hands. Hold the wood with the pliers, then you drill a lot more safely into these small parts. You may need to pad the pliers jaws with a little electrical tape wrapped around it so you don't mar the wood. And remember, you've got a lot of leverage here, so easy-does-it with the pressure. These are small parts and you could easily crush the wood. Although the author doesn't specify it, it looks like he is using a special dowel used in constructing dowel joints for his "knob". They have grooves precut in them to hold glue in their original application. Good luck.

Very cool, Cant watch the video but I get the Gyst (how about a drawing of the workings)..
Ill give you bonus points if you can do a rotary switch (multi position) and a Variable resistor using the same methods..
regards.

If you leave the switch in the on position for a long time, will the metal tab stay bent in the on position?

Looks to be a British brand, Parkside.
There's one on ebay.co.uk for around 30GBP.
Don't forget the different power connects in the world :)

it says "parkside" on the side of the sander but i can find anything that looks the same.

Had other designs in my mind. But this is probably the neatest. Good job! Info on the belt sander please ^^
