What are touch switches? Initially, the concept of touch switches meant switches with a contact plate, when touched, the load turned on and off. There are no mechanical moving parts in the touch switches.

With the advent of new devices, the concept of touch switches has changed a bit. Now, the concept of a touch switch includes all devices for which control is not required to use any direct physical impact.

The most common touch switches include: IR sensors (motion sensors), volume sensors, acoustic sensors (responsive to sound), touch switches in the form of an ordinary switch, but without a movable key ...

Most manufacturers of sockets, switches spend considerable money on ensuring maximum security for ordinary consumers and raising the level of comfort during the operation of electrical appliances.

For example, many manufacturers equip their sockets with protective curtains. It will not work to insert any foreign object other than the plug from electrical appliances into the outlet of the outlet.

These sockets are ideal for installation in apartments where young children grow. For the curiosity of the kids is no secret to anyone, many of the kids constantly strive to stick something into the socket outlet. In addition, recently, almost everyone who makes repairs install sockets at a level of 35-40 cm from the floor. The presence of curtains also serves as additional protection against ingress of foreign objects, dust, moisture into the outlet mechanism ...

After decades of research and long-term use to activate our cell phones, laptops and various power tools, lithium-ion batteries (Li-Ion) have become used in electric car technology, becoming a major milestone on the road to replacing petroleum fuels in vehicles.

According to scientists and experts, lithium-ion batteries took first place in the establishment of the prize for the title "Innovative Technology of 2010".

In recent years, electric hybrid cars have begun to gradually displace gasoline models from the international market, they have gained their advantageous position due to the safety of technologies that involve minimal emission of harmful exhaust gases into the atmosphere ...

The article describes the principle of operation of several different devices for troubleshooting in wiring. This article will be useful both for beginner electricians, and for people who are just interested.

Almost every man at least once in his life, but hammered a nail into the wall. Someone in order to hang a beautiful, expensive painting, which was recently acquired at the exhibition. Someone just nailed a shelf for a flower. And surely every second thought flashed: "But is there any electric wire or fittings?" And it’s good if you have a drawing according to which electric wires were laid. And if there is no such picture? Then everyone acts at their own peril and risk.

But in order not to get into a mess and do business, there are special devices that relatively accurately indicate the presence of electrical wiring or fittings in this place.

In this article we will consider the most popular and affordable devices for finding hidden electrical wiring ...

The article talks about the upcoming breakthrough in the field of electronics - these are conductive plastics.The TV can be rolled up. The era of flexible electronics is about to begin.

Until now, the main role in modern electronics is played by materials such as copper (wires and other conductive parts) or silicon (semiconductors, computer "chips"). We present plastics more in the form of instrument housings, insulating coatings. Material scientists think differently, they believe that in the near future organic materials based on carbon can become the main raw material in the production of radioelements, magnets, lasers.

The possibilities of plastics are endless, if you synthesize millions of molecules, replacing individual sections in them, you can create polymers with many functions ...

The article describes the most common devices for protecting your electrical equipment from voltage surges. The advantages and disadvantages of voltage stabilizers are considered.

Our power networks have been in a rather neglected state for more than a dozen years, as a result of which multiple accidents occur, which leads to the failure of household appliances.

A lot of equipment designed to protect electrical appliances is presented on the electrical equipment market. Consider only the most common devices that will help protect our devices from voltage surges.

High and low voltage protection. These devices are designed to protect both individual consumers (TV, computer, refrigerator), and the entire apartment as a whole ...

Features of the device of organic LEDs and prospects for the development of OLED technology.

For light signaling, LEDs have been used for a long time. Currently, the production of LED lamps used for lighting is actively developing. Their advantages are obvious: high efficiency, long service life, low power consumption. Now a new direction is beginning to gain momentum - the production of organic LEDs.

Organic light-emitting diodes are a set of films of organic origin, which, when passing an electric current, begin to glow. In this case, light is distributed evenly over the entire area of ​​the material ...

The principle of operation, advantages, similar heating appliances.

Electric radiators with their appearance resemble water specimens. Heat is generated in them when electric current passes through the heating element of the radiator. It is this heat that warms us.

As you know, electrical energy can be quite easily controlled. Therefore, heating systems equipped with electric radiators make it possible to regulate the indoor climate.

As noted above, electric radiators are similar to ordinary ones both in appearance and in principle of operation. The difference is that instead of water, an electric current is used. In order to transfer heat from the heating element to the walls, various liquids are used, most often this is oil. Such radiators can be controlled both through a thermostat ...
