“How to put a double switch instead of 1”: a friend asked. There are 2 options
At one time, I was often asked how to change the switch to a two-key switch. Then they stopped, and now again.
Let's remember the scheme
One-key closes the contact, a current is supplied to the light bulb, and it works.
In the circuit with a two-button switch, everything is the same, only one more wire is added, which forms the second group.
Everything is simple, from the switch to the place where the chandelier will be, you need to pierce the channel, lay the wire, connect and you're done. But, ah if repairs have already been made and don't want to make a mess? There is an option, but more on that later.
At a friend
He started a repair, and wants to remake a single into a double, and move the lighting to the ceiling, and lower the switch.
He wants to do it himself, but did not know how, I find him a phase and zero, draw a diagram, make sure that I understand. And then he tells his idea, from which he was a little taken aback.
It turns out that he will install 5 spotlights on the ceiling, and there will be an LED strip around each. One key will control the ribbons and the other the lights, came up with.
Moreover, it will fix the distribution box on the ceiling, and from it will spread the wiring with rays, and on top of the stretch ceiling. As they say, he is the master, can even install a chandelier on the floor.
About the second option
Tom, who wants a chandelier with numerous, controlled luminaires, but does not want to "throw" an additional wire, I advise. Buy a remote control chandelier, the choice is large, then it is possible without a wire get along.
