The main rule of the childhood "do not climb to the socket" all remember. But why it is impossible to do it, not each parent explained. Now, knowing features of the installed sockets and switches, it is possible to limit easily family from danger and to satisfy the design preferences.
There is set of devices thanks to which it is easy to create "ray of light in the dark kingdom".
The socket — element of plug connection which part is also the fork. That that's right! select the socket, it is necessary to know some of its characteristics and what it consists of. If it is short, then it is necessary to know material of contacts and size of tension and current on which they are calculated. The more these values, the more socket "will pull" the connected devices.
The socket basis (is more often from ceramics) rather brittle. And, of course, if the socket of old sample, and diameter of openings at it 4 mm, then the modern equipment you do not hammer with the hammer into it. The protective body not only performs function of protection from contact with the environment, but also will successfully fit into room decor. Types of sockets exists a little.
The built-in sockets are with the grounding contacts and without them. They are mounted in adjusting boxes on condition of the buried wiring. Double sockets and sockets with the switches connected in one block are installed by the same image. From modern euro sockets the following types are most popular. Sockets with the fork pusher. In corner of the body there is button which catapults fork. During the work the possibility of ejection of the device is excluded from adjusting box, wiring chafing and so on. Sockets with blinds, mainly, will save children from trouble. Blinds open only at simultaneous introduction of two metal pins of fork. Sockets for damp rooms. They can be with rubber lining or with cover for protection against drops. Most often low-power also have degree of protection of IP44. Telephone and computer sockets are (rectangular) to one or two slots and differ in the sizes of cable terminal. Are mounted near devices, but can be also distant control (smart home system).
To connect the available device in any foreign socket, it is necessary to buy various adapters under each standard of the size.
The switch is the device disconnecting and closing electrical circuit thanks to the throw contact which is in one of the modes. Switches are built in and external. But besides, their types there is huge set, often created only in the design purposes. Switches are one - two- and three-keyboard. Each key is responsible for management of the luminous source. The switch through passage operates on the contrary: one luminous source can be regulated by several switches from different places. For example, it is very convenient to turn on the light at the entrance to the room and to switch off at bed headboard.
Switches often do with illumination for simplification of its search in the dark.
Light dimmers - svetoregulyator which when pressing the button or at turn of the handle submerge the room in the twilight are very convenient or fill in with "day" light. However they have also minuses: radio interferences, high cost, incompatibility with energy saving lamps. And, of course, switches with the timer, photo cell or the motion sensor, each of which will provide power saving. However they not quite are suitable for use in apartments.
