In this article, we will consider how to make a knife switch yourself. Of course, you do not need to use such a switch in a household network, but at low voltage, for some projects, as the Master does, it is. In the manufacture of the switch, the master used the following

Tools and materials:
-Copper tube;
-Board;
-Hacksaw;
- Joiner's glue;
-Sandpaper;
- Clamps;
-Tape grinding machine;
-Hammer;
-Vise;
-Drill;
-Pliers;
-Tool for flaring;
-Pencil;
-Rule;
-Screws;
-Nuts;
-Plastic rod;
-Wire;



Step One: The Case
The switch case is made in the form of a box without a bottom. It makes a case out of a board. Cuts the board to fit. Grinds. Glues the box.

















Step Two: Making Contacts
Contacts the master makes of a copper tube. Cuts off the tube. Cuts them along. Levels. The result is a copper plate. Then from the plates, using a vice, pliers and a hammer, the contacts of the desired shape are bent. Drills holes in the contacts.











































Step Three: Connecting Rivets
The contacts mounted on top connect with the bottom contacts, copper rivets made of tube.











Step Four: Establishing Contacts
Marks and drills a hole in the housing.




Establishes contacts. Flares rivets.












Step Five: Set Moving Contact
Installs sliding contact plates. The handle is made of a plastic rod.









Step Six: Installation
From the end of the case sets the screws. Screws will play the role of contacts. Mounts wires inside the case.




The switch is ready.

For the people, I translated everything, but let the critic bother.

What do you literally translate? What for?
But really, why bother? Stupidly copied one to one, let the people themselves bother with the translation! smile

What do you literally translate? What for? I wrote everything in the article. If you are too lazy to see the photo and you criticize for the sake of criticism. You still can’t convince that the author did what he needed.

This is how the original Google translator translated this article
No, this is the author of the publication with such a pearl answered my comment:
Homemade for the sake of homemade! Your objections are also solely for the sake of the objections themselves!

This is how the Google translator translated the original article. There are also not such translation pearls, so I said that I did not read the original due to lack of knowledge of the language.

Did you see the photo? Here there is a similar type of circuit breaker.

What is not clear then? For his project, for his homemade work, the author needs a switch of precisely this type, of this appearance.

A simple slide switch has none of the sinister effects of a knife switch. An evil switch for an evil project ... The switch needs to be labeled with laser etchings for maximum effect. I couldn't bring myself to ruin it with a simple pen
Do you yourself understand what you write?

What requirements of the author does a particular homemade product meet?

I already wrote the look.
Sometimes a project is destroyed by choosing a switch.

Pay attention to the switch.

Calculate how much the cross over switch costs exactly such a plan and where could he buy it? He needs such a cutout, he made it. And as for the purchased material, and who does not buy it?

meets the requirement of the author

at a price he cut three penny cost
Calculate the cost of materials, including consumables, a copper tube, judging by the barcode sticker, is also purchased! Homemade for the sake of homemade! Your objections are also solely for the sake of the objections themselves! smile

Provided that the purchase is much cheaper and (or) better than homemade!

and she is in the nearest store and meets the requirements of the author. And his demand is not only those. conditions, but also appearance. Yes, and for the price he cut three kopecks

Well, what for a goat button accordion? What do not suit standard switches?

And why should he standard? Then you can go to the store, buy what you need, and close the site.

Even if this is done for some strange low voltage purposes:
1. No copper elasticity; contact will be unreliable.
2. Joining with rivets through a piece of wood is a strange undertaking.
3. Making plates from a tube is no less strange.

no need to use such a switch in a household network
Well, what for a goat button accordion? What do not suit standard switches? Especially home-made with uninsulated contacts!

Read. Something did not find in the text how and in which place author uses a switch, but in the photo I see an incandescent lamp, very similar to a halogen one, and from which it follows that it is low-voltage? I didn’t read the original text, it’s not strong in “foreign” ones, but most likely the original crafts are used as a visual aid to demonstrate load switching from two sources, and nothing more.

Then we wonder ... where do the fires come from? A crazy idea ... the tree is still dry, which is no dielectric, but moisture is grabbing ... here you have a short circuit ...
