How to choose a switch?

For a long time the switch was consideredOnly as a functional element of the interior. That's why nobody tried to choose them. People believed that the better the switch, the better. With the appearance of a variety of switches, their choice has become different. But how to choose a switch? We will tell you about this in this article.

Switch selection

There are several ways to fix the wiring of the switch:

• Screw. They are intended for aluminum wiring. This wiring has the property of deforming, heating and, in some cases, sparking. To use such devices, you only need to tighten the screw that holds the aluminum wire so that the switch again becomes operational;
• Screwless. They are designed for copper wiring (such wiring is put in new buildings). Here you can buy switches with a screwless terminal (on the terminals).

When choosing a switch, it is also necessary to find out what kind of wires are installed in the building (hidden or open wiring). Depending on this:

• If the wiring is open (this has been preserved in the village houses and "stalinkas"), then it is necessary to take a switch of the overhead type.
• If the wiring is hidden, then you can install switches with a box that is installed in the wall. And already to such a box, with the help of screws, the case of the switch itself is fixed.

Also, there are single-key, two-key,triklavishnye and so on switches. For example, in the range of a number of American and Asian firms, there are six-key switch models available. Experts believe that it is not necessary to put switches with a large number of keys, since this can negatively affect their correct operation.

By functionality, the switches are divided into:

• Ordinary.
• Control, also called indicator.
• Light-controlling.

Also, when choosing a switch it is necessary to carefullylook at how moving parts move in these devices (except for switches controlled by the remote control). These elements of the switch must move freely, without hanging.

Today, the appearance of the switches is important. For example, there are switches that have a multi-colored interchangeable frame. It can be matched to the color of your walls. Also there are models in which there is a key illumination. Such switches will work as a beacon at night. It is important to purchase switches of proven manufacturers.

Before buying a switch,Learn how much power it can withstand. If the switch is not designed for the power that you have, then it can quickly break down. To prevent this, buy switches with a small margin of power. Now you know how to choose a circuit breaker.
