Control of lighting from two parties through switches.

Installation of a junction box for lighting control from two places for a pass-through switch.

Connecting walk-through switches

Ten wires are brought into the junction box: two power; three per pass switch; three on another pass switch; two per lamp.

It is necessary to determine all the wires by testing with an ohmmeter, feeding the wires with a phase voltage indicator and a test lamp.

Zero working conductor (N) we connect to the wire of the lamp, which is connected to the side contact of the electric socket. Phase conductor (L) is connected with the outgoing wire to the first pass-through switch, which is connected to the middle contact. Two control wires of the first switch are connected to two control wires of the second switch. We connect the middle contact of the second switch to the wire of the lamp connected to the central contact of the electric cartridge.

Protective neutral conductor (PE), is not taken into account in the scheme.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Removing scratches from a car with sunlight 15.08.2022

The appearance of scratches on the car is inevitable. They spoil the overall look and you have to turn to specialists to eliminate them. However, thanks to the development of Korean scientists, everything will soon be possible to do independently and without much difficulty.

Specialists have created an innovative tool that needs to be applied to a scratch and put the car in the sun. After half an hour, the scratch will disappear. According to the inventors, this material contains a polymer network based on acrylic polyol. Under the influence of infrared rays, a chemical reaction occurs, restoring minor damage at the site of application of the product.

The regeneration process can be accelerated. To do this, you need to use concentrated light. Take, for example, a magnifying glass. In this case, the waiting time can be reduced to 30 seconds.

The team of creators noted that the tool has a transparent texture, so there is no need to match it to the color of the car. The novelty will go into production in the near future.
