A household single-pole switch, from the moment it is installed, the consumer gets used to its location and even at night can easily turn it on by pressing a key.

If you pay attention to the direction of the vertical pressing of the switch keys, then sometimes they turn on and off from different places in the same building or apartment in different directions.

For convenience and consistency, I set the switches so that pressing the top of the key will turn on the light, and pressing the bottom of the key will turn it off.

As well as sockets, the installation of switches in children's institutions should be 180 cm from the floor, and the distance from pipelines, bathtubs, sinks, etc. should be at least 50 cm.

In other rooms, I use the following installation dimensions:

height from the floor, 110 cm;
distance from the corners of the door frame to the switch, from 15 to 25 cm.

The recommended cross-section of connected wires is 1,5 square millimeters.

A circuit breaker for protecting lighting groups, it is better to use a current of no more than 10 amperes.

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. ... >>

Huawei CableFree 5G Antennas 30.05.2020

Huawei announced a breakthrough in the development of 5G antennas. A new design called CableFree improves the capabilities of 5G base station antennas. This communication standard provides for the use of new bands and more antenna connections. And the new design provides better coverage in the 5G high-frequency band. According to the company, CableFree improves the radiation efficiency of the antenna by about 20%.

To support the higher capacity and additional antenna connections used for 5G communications, the antennas must be capable of handling 1kW. For communication of the previous generation, a power of 500-600 watts was enough. The CableFree design increases the power of the antenna by more than 80% and also reduces the weight of the antennas, making them easier to install. The six-band antenna based on CableFree is about 10 kg lighter than analogues, and the weight of multi-channel antennas is immediately reduced by 50 kg. Thus, they do not require a crane to be installed, which saves time and money during the network deployment process.

At the same time, CableFree reduces the use of screws and solder points by up to 80%, reducing the chance of passive intermodulation or signal distortion and interference caused by large metal objects. This, in turn, makes it easier to automate the production of antennas while keeping their quality unchanged.
