Cross switch

When considering repairing in an apartment or a house, one of the main points that should be paid special attention is engineering networks. And if the arrangement of the sewerage or the water main is largely dependent on the external conditions, then the wiring can be planned as the soul desires. Carefully consider the placement of electrical installation equipment - sockets and switches, as it depends on them the level of comfort. And if in small apartments it is quite enough ordinary switches, then in large houses you can not do without cross switches that allow you to control the light from several points simultaneously.

The difference between the cross switch and the gate

First, let's figure out what the cross switch is. As is known, the conventional switch has two positions, in each of which, the electric light source connected to it switches on or off. Structurally, they have two contacts corresponding to its on and off state. Pass-through switches have not two contacts, but three and allow you to control lighting from two different points. Thus, you can light the light by pressing the switch at one end of the room and extinguish it by pressing a similar switch installed at the other end. Pass-through switches are convenient to install at different ends of the long corridor , in the passage rooms or on either side of the double bed in the bedroom. If there is a need for more control points, the circuit between cross-connect switches includes cross-connects. Structurally, they are similar to checkpoints, but have additional contacts. For example, to control the light from three different points between two pass-through switches, put one two-key cross, which acts as a switch, which coordinates the work of the pass-through switches.
