Installation of a junction box for one group of lighting, for a one-gang switch and a luminaire for one group of lamps.

Connecting a single-gang and two-gang switch

Six wires are brought into the junction box: two power wires; two per single-gang 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 to the switch wire. The remaining two wires, from the lamp, connected to the central contact of the electric cartridge and the switch, are connected to each other.

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

Two-button switch

Installation of a junction box for two groups of lighting, for a two-gang switch and a luminaire for two groups of lamps.

Connecting a single-gang and two-gang switch

Eight wires are brought into the junction box: two power; three for a two-gang switch; three 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 contacts of the electric cartridges. Phase conductor (L) is connected to the switch wire, we define it as the middle conductor. The remaining two control conductors from the switch are connected to two wires from the lamp, connected to the central contacts of the electric sockets.

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. ... >>

Interchangeable optics for smartphone 12.07.2020

Huawei continues to work on methods to improve the quality of shooting in smartphone cameras. The next patent received in the European Intellectual Property Office (EUIPO, European Union Intellectual Property Office) describes the use of interchangeable optics for a smartphone.

Huawei now has the flagship Huawei P40 Pro + with a 10x optical zoom in its assortment. Such parameters are achieved using the periscope module of the main camera. At the same time, the Huawei P40 Pro consistently ranks first in the DxOMark ranking, and the Huawei P40 Pro + has not yet been tested by the specialists of this laboratory.

However, with all its advantages, periscope modules also have disadvantages. Huawei has found a way around them in a new patent. It describes a smartphone with a triple main camera, where two sensors are relatively small and a larger third sensor can be used with interchangeable lenses.

Motorola has already tried to implement a similar development with Moto Mod modules, but has not been successful. As is usually the case with patents, it is currently impossible to say with certainty whether the project will be brought to a commercial stage and whether its implementation will appear on store shelves.
