An overview of modern switches

Katya CHP Finally, changing a flat, I got rid of the invention of a domestic Kulibina with a tricky name "switch with pull cord. What is it, he knows, probably everyone. Keep in mind: to light up, have a long fumble on the wall to catch every now and then slip out of the hands norovyaschie zamurzanny lace hanging from the ceiling, and then finally held him, struggling to pull? If you're lucky - the switch works and the light will light. But as time "trigger mechanism" chatter, have to pull a few times ... So, thank God, those suffering in the past. Now I just click on the button switch. True, and there are some inconveniences. Firstly, from the previous owners I got switches quite "mature." Second, our builders for unknown reasons set switches is quite high. So I decided to do everything right. To switches in the house were all the rules of modern electrical science. But first let's define what is right, a modern switch. For information: The indicator light - a glowing "eye" on the key breaker control switch - a switch with indicator lamp, which features on or off lights, dimmer (dimmer) - combines the functions of switches and controls the brightness of light; Mounting box - hollow box, which inserted and fixed into the wall. In her place the wires and the inside of the switch. By way of fixing the wires are divided into circuit-breakers with screw and screwless terminals in the first case, a wire with a screw clamp between the contact plates. This method of fixation is good for aluminum wires: in the process, they can heat and over time gradually deform (as the experts say, are beginning to flow). Then contact weakens, sparks, hot. But need only twist the screw - and everything is in order. Copper wires can connect screwless terminals - a special terminal. Quickly, easily and securely. By way of installing switches are divided into flush switches and open wiring, for example, in the cabins or in the old Stalinist homes wires are usually secured from the outside, on the wall - this is an open posting. For her, there are special "overhead" breakers. Now in urban apartments, usually the wire removed in the wall. And in the place where the switches are set, a small hollow cavity. By the way, if before the switches were kept only by the "legs", rest against the wall, then there is recent metal mounting plate with holes: the cavity wall installation box is placed, and by her screws fixed switch. What are the switches? Most often encountered in selling one-and dvuhklavishnye switches, at least - trehklavishnye. In Europe, for example, if you need more keys, one-key group or dvuhklavishnyh switches combine common border. The Americans and South Korean producers are not limited to three buttons. They make even shestiklavishnye switches, and on each key - indicator lights. It also distinguishes their products from the European circuit, where the indicator lights are only in one-key versions. One-key switch, Dvuhklavishny switch Trehklavishny switch, dimmer (dimmer) with a total load of 300 W Possibilities of modern circuit breakers are not limited to turning on and off the light. Some of them turned into switches. What is it, I will explain with an example. One of my friends have such a device in the country. Going down at night from the second floor at first, he was one switch turns on the light at the top, while others - off the bottom. Very convenient. Layman to distinguish the switch from the switch in appearance, of course, difficult. Therefore, virtually all foreign producers draw the connection diagram on the inside of the device. Wonderful thing - switches to control lights and switches. True, resemblance, they are working on different paths. On the switch with light installed already mentioned indicator light. It will show the location of the switch in a dark room or hallway: do not have to fumble hands in the dark, bumping into furniture and sharp corners. But a burning lamp on the control switch signals: the device (or light) is turned on. Such a switch can be installed, for example, at the entrance to the basement to know where the light is lit or not. The lamp is not lit - so, in the basement is dark, and vice versa. For switches and dimmers can be attributed, or dimmers. They not only light the light, but also allow you to adjust the brightness - from the blinding lights to muted intimate lighting. To properly select a device, you must know the total load that it can withstand. For example, the figure is 300 W, marked on the dimmer, means that it can be used to change the brightness pyatirozhkovoy chandeliers with light bulbs on 60 watts. However, just in case we recommend to buy dimmers "with reserve". Switches for bathrooms, saunas or for installation on the street, naturally, differ from the ordinary. That they can withstand high humidity, street dust and dirt between the decorative cover and the inside of the switch put plastic or rubber sleeve. At one firm told me that their staff have put the experiment: at home in the bathroom every time they pour a switch from the shower. And what happened? It's been a whole year, and the switch is still working properly. What is a vandal-proof switches? It turns out that today there are. In principle, they are intended for public spaces, make them, usually from impact-resistant plastic or metal. Break or smash an "enhanced version" - not an easy task. By the way, do not just metal vandal-proof switches, but also expensive, exclusive series. But mostly the case breakers - made of plastic, while the inner part - of the materials are not conductive (special composite materials). Because of what often break these devices? Firstly, because of poor contact wire and contact plates: the switch starts to heat up, spark. At best, the plastic casing may melt, at worst - there fire. Secondly, the "longevity" switch depends on the mechanical strength of plastics and ceramics. For example, the switch can be accidentally hurt or hit. Brittle plastic will not scratch, but it can crack. More plastic bear attack, but eventually scratched. The bad ceramics, it happens, crack almost immediately, even during installation. How to choose a good switch? Here are a few simple tips. Carefully inspect the selected switch. On the inner side should contain the values ??of current and voltage, for which he designed, and an icon of quality standard of the country where it is produced. On the domestic circuit breakers, or packaging of imported should be a sign of our Rostest - a sort of guarantee of the state from potential trouble. The difference between "kondovym" cheap switch and a quality product with clean lines and smooth surface, in principle, it is easy to see. If you want to be 100 percent sure of the quality of their purchases, buy the switches reputable firms. Incidentally, the large manufacturers a choice of models, colors and series of switches is enormous, and every year there is something new. P.S. As a result of their "market research" I came to the conclusion that I probably fit the system control switches, which is implemented with a remote control (much like a television remote control). Of course, this is fun is not cheap, but comfort is more expensive.
