Electrical accessories today are represented by a wide assortment, since sockets and switches are multitasking electrical devices. They are operated under various conditions, therefore, when choosing, you need to take into account the functional characteristics, appearance.
Choosing sockets and switches for home, office, industrial premises. Consider the following points:
- voltage in the electrical network;
- installation method;
- functional purpose of the room.
What do the characteristics of the power grid affect?
Sockets and switches are the finishing points of a complex technical scheme for "transportation" of electricity. These elements are selected taking into account the type of consumers that will be connected. In residential premises, networks are laid, which at the finish line give out a voltage of 220 V. This voltage is sufficient for the operation of familiar household appliances, therefore the sockets are called "household". Household models of 16 A are considered the best option for modern apartments, to which you can connect both kettles and PCs, as well as more powerful equipment, for example, electric ovens, heaters.
To connect industrial and agricultural equipment, networks are used that provide a voltage at the level of 380 V. It is for these characteristics that sockets are selected, through which power is subsequently provided for electric grinders, compressors, and factory machines.
Types of electrical accessories by installation method
According to the installation method, the sockets are divided into three main groups:
- waybills;
- built-in;
- retractable.
Each of the types presented has a certain set of both advantages and disadvantages. Overhead products are quick and easy to install, captivating modern consumers. In the event of a breakdown, an operative replacement is carried out. Models can be fixed not only on the main walls, but also on partitions. You can install overhead sockets at any stage of the repair, including after the completion of finishing.
If you are confused by the appearance of the overhead options, then stop at the internal models. They are distinguished by a presentable look, since the panel is hidden in the wall. Outside, only the decorative part is visible, which can have any shape, size, color. The design is selected taking into account the style of the room decoration.
Retractable modifications are relevant for the kitchen space. These are ergonomic units that can be integrated into walls, kitchen cabinet panels, countertops and floors. The rosettes are closed with decorative covers, which are matched to the tone of the surface.
The choice of switches is no less varied:
- simple;
- cross;
- checkpoints.
Simple switches are familiar to many as they are installed in most apartments. Cross and pass-through models are less common, but the demand for them is growing. Externally, the rotary switch is no different from the usual modification, but it consists of 2 contacts instead of the usual 2. An additional movable contact provides convenience. Instead of one switch, two are mounted, for example, at the entrance to the room and near the bed in the bedroom. To turn off or turn on the light, you can use any of the devices. The cross switch has 4 contacts. Such models are installed in long corridors at three points. A three-core wire is required for the system device. Pass-through and cross switches are a convenient aid that you should pay attention to when choosing electrical devices for an apartment or a country house.
