What is Automobile switch:
It is a device installed on the automobile steering column and composed of more than two switches used to control automobile lights, signals, control electrical appliances and other components.
Automotive Replacement Toggle Switches is a switch often introduced as a power supply in the electrical control circuit. It can be used to directly start or stop the low-power motor or make the motor forward and reverse.
Classification of FBelec automotive switches:
In the field of switching power supply technology, people develop relevant power electronic devices while developing switching frequency conversion technology. The two promote each other and promote the development of switching power supply towards light, small, thin, low noise, high reliability and anti-interference at a growth rate of more than two digits every year. Switching power supply can be divided into AC / DC and DC / DC. DC / DC converter has realized modularization, and the design technology and production process have been mature and standardized at home and abroad, and have been recognized by users. However, due to its own characteristics, AC / DC modularization has encountered more complex technical and process manufacturing problems in the process of modularization. The structure and characteristics of the two types of switching power supplies are described below.
Selection method of automobile switch,car rocker switch:
On the market, there are many kinds of switches and sockets, good and bad, so that consumers are at a loss when purchasing. Switches and sockets are not only a household functional product, but also the main parts for safe power consumption. Their product quality, performance and material play a crucial and decisive role in preventing fire and reducing loss.
Eye view: generally good products have flat appearance, no burr, bright color and its material adopts high-quality ABS + PC material, with good flame retardant performance and non fragile. Although the surface of some products is bright and clean, it seems to be coated with a layer of oil, but the color is pale and the texture is coarse. This kind of material has poor flame retardancy. You can ignite it with fire to try its flame retardancy. If it burns out quickly, it is good plastic, otherwise it is very poor plastic.
Hand press: a good product panel will not be removed directly by hand, but must be removed with the help of certain special tools, while ordinary non mainstream medium and low-grade products are easy to remove the lower cover by hand, resulting in indecency in homes and public places. When selecting, use the index finger and thumb to form an end point diagonally according to the face cover, press one end firmly, and press the other end hard. The quality of the product with loose and sunken face cover is poor, otherwise, the quality is reliable.
Ear listening: gently press the switch function, the lighter the sound of the sliding plate, the smoother the hand feeling, and the stronger the sense of rhythm, the better the quality; On the contrary, when opening and closing, the sound is impure, dynamic and astringent, and the sound with midway intermittent state is of poor quality.
Look at the structure: there are two general Switches for Cars, Trucks & SUVs structures:
1. Sliding plate type and swing rod type. The sound of slide switch is pure and thick, and the hand feel is elegant and comfortable. The swing bar type has a crisp sound and a slight metal impact sound. It is more stable than the traditional sliding plate type structure in eliminating arc and service life, and the technology is mature.
2. Double hole pressing plate wiring is safer than screw crimping.
Because the former increases the contact area between the conductor and electrical parts, it is resistant to oxidation and is not easy to loose, poor contact and other obstacles. When the latter screw is firm, it is easy to crush the conductor, and the contact area is small, which makes the electrical parts easy to oxidize and age, resulting in poor contact.
Material selection: pure silver switch has strong conductivity, low calorific value and high safety performance. If the contact is made of copper, the performance will be greatly reduced. The socket material adopts Tin Phosphorus raw copper sheet, which can get the best strength, toughness, elasticity and other indicators. It is dozens of times more durable than the socket with general brass as reed, and there is rarely the phenomenon of strong arc burning the socket when inserting the board. The gold-plated spring needle is extremely difficult to oxidize and has stable performance, which can ensure clear and true sound quality and fast and accurate data transmission.
Look at the sign of switches for automotive: the rated current of the household general switch commonly used in the market is 10a, and the socket current is 10A or more,
Bran recognition: FBelec products have been strictly tested by time and market. They are recognized as safe products in the eyes of consumers. They are strictly controlled in terms of material and quality. There are high-quality processes in all aspects of packaging, transportation, display and image design. FBelec products are not only safe electrical functional products, but also exquisite and elegant works of art that reflect elegant cultural taste.
Today is an era of pursuing fashion. Although electrical products are not a kind of public daily consumer goods, like mobile phones, exquisite styles, designs with different styles and creative ideas are all for safer and more comfortable life.
Automobile switch, in fact, no matter from which aspect, families should choose some famous brand products. These products are not only of high quality, novel styles and various specifications, but also safe and reliable.
