SOCKETS and switches: types, device, connection


Sockets and switches: types, device, connection</a>

The main rule of childhood "do not climb to the outlet" remember everything.

But why not do this, explained not every parent.

Now, knowing the features of the installed sockets and switches, you can easily limit the family from danger and satisfy their design preferences.

There are many devices that make it easy to create a "ray of light in a dark realm."


The socket is an element of the plug connection, partWhich is also a fork. To properly choose an outlet, you need to know some of its characteristics and what it consists of. In short, it is necessary to know the material of the contacts and the magnitude of the voltage and current to which they are calculated. The more these values, the more rosette "pull" the connected devices.

The base of the outlet (often made of ceramics) is sufficientFragile. And, of course, if the socket of the old sample, and the diameter of its holes is 4 mm, then modern technology should not be hammered into it with a hammer. The protective case not only serves as a protection against contact with the environment, but also successfully fits into the decor of the room. There are several kinds of outlets.

Built-in sockets have earthing contactsAnd without them. They are mounted in the installation boxes provided that the wiring is hidden. In the same way, double sockets and sockets with switches connected to one unit are installed.

The following types are the most popular from modern European rosettes.

Sockets with a fork ejector. In the corner of the case there is a button that catapults the plug. During operation, the possibility of pulling the device out of the installation box, wiping the wiring and so on is excluded.

Outlets with curtains, mainly, will save children from trouble. The shutters open only when two metal plug pins are inserted at the same time.

Sockets for wet rooms. They can be with a rubber lining or with a lid for protection against drops. Most often low-power and have a degree of protection IP44.

Telephone and computer outlets come with oneOr two sockets (rectangular) and differ in the dimensions of the cable lug. They are mounted next to the devices, but there can be remote control (smart home system).

In order to connect the existing device to any foreign outlet, you need to purchase various adapters for each standard size.


A switch is a device,Disconnecting and closing electric circuit due to a changeover contact in one of the modes. Switches are built-in and external. But besides this, there are a lot of their types, often created exclusively for design purposes.

Switches are one-, two- and three-key. Each key is responsible for controlling its light source. The pass switch operates in reverse: one light source can be controlled by several switches from different locations. For example, it is very convenient to turn on the light when entering the room and turn it off at the head of the bed.

Switches are often made with backlighting to facilitate its searches in the dark.

Very convenient dimmers - dimmers, whichWhen you press the button or while turning the knob, immerse the room in the twilight or fill it with "daylight" light. However, they also have disadvantages: radio interference, high cost, incompatibility with energy-saving lamps.

And, of course, switches with a timer, photocell or motion sensor, each of which will save energy. However, they are not quite suitable for use in apartments.
