The waterproof touch switch is an electronic switch, which can be turned on by lightly pressing the switch button when using. When the hand is released, the switch will be turned off. The internal structure of the switch is realized by the force of the metal spring. Waterproof tap switch: as the name implies, it is a kind of tap switch that can be waterproof, but it has requirements for waterproof, which is not to say that it is called waterproof after passing through the water without affecting its performance. The real waterproof effect is to achieve the waterproof effect of IP67 industrial level to be called waterproof tap switch. IP67 now refers to the mobile phone industry protection security level IP abbreviation, which defines an interface for the protection of liquid and solid particles. IP is followed by two numbers. The first is solid-state protection level, with the range of 0-6, indicating the protection from large particles and foreign matters to dust; the second is liquid protection level, with the range of 0-8, indicating the protection from vertical water drop to underwater pressure. The larger the number, the stronger the representation. IP67 is interpreted as protection against dust inhalation (overall protection against contact, protection against dust penetration); protection against brief immersion (protection against immersion).

 

At present, the highest level in the cabling industry is IP67. In addition, the industrial connector also has the consideration of temperature, vibration and other factors for other harsh environment. LED lighting, also known as semiconductor lighting or solid-state lighting, is made of light-emitting diodes. The water-proof light touch switch LED driving power supply is a power device used to drive the normal lighting of LED lights. The core of light touch switch is led driving chip, and the blade switch is also called LED driving IC. There are many problems in the early LED driving power supply which mostly adopts constant voltage mode. Main technical parameters: waterproof grade, high contact, internal a contact, round multi-point contact, water resistance: temperature 60 ℃, time 24h, maximum rating: 12V DC 50mA, minimum rating: 1V DC 10uA, contact resistance: 30m Ω max, insulation resistance: 100M Ω min, voltage proof: 250V AC (50-60Hz) for 1min. Material material: copper, silver or gold plating can be selected for material pin, and one hundred thousand or one million times for shrapnel.

 

1、 For example, there are 2.5gb/s and 5.0gb/s wireless product connectors, optical fiber connectors, broadband connectors and thin spacing connectors (the spacing is 1.27mm, 1.0mm, 0.8mm, 0.5mm, 0.4mm, 0.3mm) with height as low as 1.0mm-1.5mm in the market.

 

2、 Press fit contact technology is widely used in cylindrical slotted socket, elastic stranded pin and hyperboloid spring socket connector, which greatly improves the reliability of the connector and ensures high fidelity of signal transmission.

 

3、 Semiconductor chip technology is becoming the driving force of connector development in all levels of interconnection. For example, with the rapid development of 0.5mm spacing chip packaging to 0.25mm spacing, the number of device pins of level I interconnection (internal IC devices) and level II Interconnection (device board interconnection) is from hundreds of lines to thousands of lines.

 

4、 Blind matching technology makes the connector form a new connection product, push in connector, which is mainly used for system level interconnection. Its biggest advantage is that it does not need cables, it is easy to install and disassemble, it is easy to replace on site, it has fast plugging speed, smooth and stable separation, and it can obtain good high frequency characteristics, which is suitable for spacecraft.

 

5、 The assembly technology has developed from tht to SMT, and then to MPT. The active use of MEMS is the power source to improve the connector technology and cost performance.

 

In the aspect of switch, the switch will develop towards miniaturization, thinness, chip, compounding, multi-function, high precision and long service life, and they need to continuously improve the comprehensive performance of heat resistance, cleaning, sealing and environmental resistance. They can be used in various fields, such as CNC machine tools, keyboards and so on. With electronic equipment circuits, they can further replace other on / off switches, potentiometer encoders and so on. In addition, the development of new material technology is also one of the important conditions to promote the technical level of electrical plug-in components. At present, there are some key common technical problems in the key development products of China's electrical plug-in components industry: first, the application technology and research of new metal / non-metal materials such as high elastic contact materials, wire spring materials, nano materials, materials with memory function, environmental engineering plastics, etc. can not keep up with the actual needs of production and manufacturing; second, new professional technology, micro processing And manufacturing technology, automatic comprehensive testing technology, reinforcement technology and experimental technology under special environment conditions, structural optimization design technology, reliability design technology, hybrid structure design technology, etc. need to meet the requirements of electrical plug-in components with more and more complex structure, more and more powerful function, and smaller and smaller volume.

 

In the low-voltage rectification and filtering circuit of waterproof light touch switch, diodes and capacitors are also used to rectify and filter the pulsating voltage after the transformer is depressurized at the beginning of high frequency, and the capacitors used in the rectification part cannot have too large AC impedance, otherwise the high-frequency AC components in it cannot be filtered out. Therefore, the capacitance selected should not only have a large capacity, but also a lower AC resistance In addition, one or two large inductive coils with magnetic core can be seen, which can filter the high-frequency AC component together with the filter capacitor to ensure the output of pure DC.
