Waterproof Switches in the market competitiveness of how?
With light switch, Waterproof Switches copper thick, to enhance the current through the ability to reduce the resistance of copper itself; toughness, especially for the switch to switch the socket part, not easy to deformation. Even if the long-term use of the switch, but also to maintain the appropriate clamping force to ensure that the plug and plug tightly connected to reduce the arc; anti-oxidation, no rust, reduce corrosion caused by corrosion resistance and heat problems; So that the overall piece of copper, to further reduce the riveting switch the current capacity and pressure, the switch's nominal current should not be less than the electrical load of the operating current.
With the lamp Waterproof Switches carefully check the product packaging on whether there is a detailed manufacturer or supplier address, telephone. As far as possible to the formal purchase channels of regular stores to buy brand products. The main switch brand on the market generally use PC material, PC material, also known as bullet-proof plastic, impact resistance, high temperature, easy to change the characteristics of the control for the electrical switch is very important.
Better switch front panel and the back of the base are used PC material, and the general switch will be in the base with black nylon material to replace PC material, so the cost can be reduced a lot. The same PC material, a lot of switch manufacturers are domestic production, and now the domestic fact, there is no company has the ability to produce PC material, the so-called domestic production are generally re-processed with the back material, so the impurities are relatively high Very brittle, heat resistance is also significantly poor.
At present, the market switch socket variety, good and bad, so that consumers do nothing at all, and Waterproof Switcheses and sockets is not only a home decoration function supplies, but also the main parts of safe electricity, its product quality, performance material for Prevention of fire, reduce losses have a crucial decisive role.
Why should the lighting switch be connected to the fire line?
If the lamp Waterproof Switches installed in the zero line, although the lights are not lit when the lights, but the head of the phase is still connected, and people think that the light does not shine, it will be mistakenly considered to be in a power state. And in fact the voltage on the ground point of the lamp is still 220 volts of dangerous voltage. If the light is off when people touch these actually charged parts, it will cause electric shock. So a variety of lighting switch or single-phase small-capacity electrical equipment switch, only in series on the line of fire in order to ensure safety.
With a fixed hole Waterproof Switches can be selected normally open or normally closed type, the original intention is normally open type Waterproof Switches and normally closed temperature control switch in the environment is the initial state is connected and disconnected, normally open temperature control switch at room temperature The case is off, normally closed temperature control switch at room temperature is closed. Such products are widely used in: drinking fountains, water heaters, sandwiches toaster, dishwashers, dryers, disinfection cabinet, microwave ovens, electric coffee pots, electric boilers, refrigerators, air conditioners, plastic machines, office equipment, car seats Heaters and other electric appliances. With stable performance, high precision, small size, light weight, high reliability, long life, the small dry and so on the characteristics of the radio.
1, the use of contact temperature-sensitive installation, Waterproof Switches the metal cover should be close to the installation of the control device surface, in order to ensure that the temperature effect, should be coated with thermal conductivity on the surface of the thermal grease or other similar thermal conductivity medium.
2, the installation can not cover the top of the collapse, loose or deformation, so as not to affect performance.
3, Waterproof Switches can not let the liquid into the temperature control switch to the shell cracks, not free to change the shape of the external terminal.
4, the product is not more than 5A current circuit used, Waterproof Switches should choose copper core section of 0. 5-1 mm2 wire connection; not more than 10A current circuit used, should choose copper core section 0.75-1.5 mm2 wire connection
5, the product should be less than 90% relative humidity, ambient temperature below 40 ℃ ventilation, clean, dry, non-corrosive gas storage in the warehouse.
