All Customer, Perhaps you have noticed that the recent “dual control of energy consumption” policy of the Chinese government has had a certain impact on the production capacity of some manufacturing companies, and the delivery of orders in some industries has to be delayed. In addition, the China Ministry of Ecology and Environment has issued the draft of "2021-2022 Autumn and Winter Action Plan for Air Pollution Management" in September. This autumn and winter (from October 1, 2021 to March 31, 2022), the production capacity in some industries may be further restricted. Gangyuan’s current power limit is Tuesday, Thursday, Friday, and Sunday. ( Adjusted at any time according to government arrangements ) To mitigate the impact of these restrictions, we recommend that you place an order as soon as possible. We will arrange production in advance to ensure that your order can be delivered on time.

The tact switch is a product with the fastest growth in market demand and the widest application in the past ten years.During the development of the four major products of color TV, video recorder, audio system, and VCD, the tact switch has also gained a larger share. develop. Tact switch classification The types of tact switches are standard type, sealed type, SMD type, waterproof type, pendulum type, long type, vertical type, semi-circular array thin type, etc., with light type (red, yellow, green), and the appearance is square, Rectangular type, round type, flat type, convex type, vertical type, long-life type, the main installation forms are plug-in welding type, embedded pin type, surface mount, etc.The advantage of light touch switch is that it is suitable for high-density surfaces Mounting, some can be cleaned after soldering, sealed type can be waterproof and dustproof, very suitable for harsh environments, simple circuit design, product life ranging from 100,000 to 10 million times. Application of light touch switch At present, light-tact switches with light are widely used in portable consumer digital electronic products, household appliances and office supplies, instrumentation and other fields, such as a set of color TV sets of 6 applications, and a set of combined audio applications about 20 sets. Nowadays, the scope of application is still expanding, and the main areas are medical electronic products, car audio, automatic control systems, testing and measuring equipment, automobile transportation and so on. The tact switch market continues to be optimistic, and the competition is becoming more and more fierce. It is mainly manifested in the production specialization and automation. The output has become more and more concentrated in a few powerful and large-scale enterprises, plus DC power supplies. The price of sockets has been falling all the way, and the profit margin is getting smaller and smaller. The situation of one or two hundred companies producing more than a decade ago or more than 20 years ago has been changed. Production is basically concentrated in more than a dozen representative foreign-funded companies and mold technologies. In the hands of joint-stock and private enterprises with strength and advanced processing equipment. Tact switches have now become the most demanded switch category in China, and they are also one of the most exported and imported products.

In last weekend, September 12, 2021 Gangyuan opens a brand new work place in Shenzhen, Guangdong Province. That's an important activity for all our stuffs and customers. We all took part in this great moment and celebrate for Gangyuan's another development. In the new workshop, we will focus on R&D for new tact switch and automobile related switches for all our customers. With new workshop openning, let's witness Gangyuan Electronics make top-level switches for everyone and provide better services.

The MS15A Series micro switches are the perfect solution for your automotive needs. Beginning of 2021-a manufacturer with more than 25 years of experience Gangyuan has developed a new car micro switch, MS15A-A (applicable to Car Electronic handbrake ) The MS15A-A IP67 waterproof micro switch is a dual-circuit detection switch. Compared with the traditional switch, it adds a disconnected normally-on function detection circuit. It can be used in a functional feedback system to ensure the safety and stability of the entire system. Waterproof and dustproof can reach IP67 standard, except for terminals. Surface mount sliding contact micro switch product advantages have high reliability, electrical life of up to 100,000 times; and large stroke, the maximum switch stroke can reach 2.6mm; waterproof and dustproof can reach the IP67 standard; the switch instantaneous function switching is completed within 20ms. High reliability, so as to ensure the safety and stability of the customer system. The switches measure 15.4×7.4×7.5mm. Maximum rating is 50mA,18V DC  and contact resistance is 75mO maximum and 200mO maximum after lifetime. Operating load is 300,000 cycles (50mA 18V DC).

Working principle of self-locking tact switch The self-locking tact switch is a kind of passive components and cannot be used alone. It can only be used with active components to form a set of control system, and its function can be brought into full play. The working principle of the normally open tact switch: press the switch button to turn on the switch when it is working, and the switch is off when the button is released, and its internal structure is realized by the force of the metal shrapnel. The principle of normally closed tact switch: Press the switch button to turn off the switch while working, and the switch is turned on when you release your hand. How does the self-locking tact switch work？ (1) When the power is turned on, when C9 is charging, the base and emitter of transistor Q1 are connected to the positive electrode of the battery power supply, Q1 is turned off, and the base of transistor Q2 is turned on to ground and Q2 is also cut off, so the circuit is cut off. , VCC 0V. (2) When the touch switch is pressed, C9 discharges and C10 charges. Since the capacitor voltage of C9 does not change immediately, the base voltage of Q2 immediately becomes the capacitor voltage of C9. In other words, Q2 quickly saturates and ignites, while C9 discharges through R18. Set the collector voltage of Q2 to a saturation voltage of 0.3V. At this time, the voltage of the capacitor C9 is also 0.3V, and the voltage of the capacitor C10 is also 0.7V. The battery power is distributed in series through R16 and R17, where Q1 is saturated and turned on, so the circuit is turned on. When turned on, VCC is approximately the battery supply voltage. (3) When the touch switch is pressed again, C9 is 0.3V and C10 is 0.7V, so C9 is charged and C10 is discharged, so the node of Q2 is reverse biased and the battery is on time. It charges C9 to R18 and is based on Q1. The pole voltage increases, Q1 turns off, the circuit turns off, and VCC becomes 0V.

Recently,theHigh-tech Fairin Shenzhen has attracted the attention of many people. More than ten majors, covering all fields. This year's Hi-Tech Fair, all kinds of technology products are still full of black technology, which is dazzling. New technologies and new equipment represented by artificial intelligence, 5G, and big data have become the "stars" of the China Hi-Tech Fair. These high-tech products with wisdom and innovative elements all hint that human life can be more beautiful in the future. Many of these products are inseparable from the shadow of electronic switches. Especially in this aspect of smart life. Our company has a case where the touch switch KAN6247 has been successfully applied to Bluetooth headsets. The Bluetooth headset mobile audio that appeared at this high-tech fair will also be the direction to overcome in the future; in addition to the first time, you can also look forward to the vehicle-road collaborative communication Terminals, the shadow of electronic switches that will appear on portable mobile computing platforms. Not only that, the appearance of industrial robots and food delivery robots at the Canton Fair, etc., all have the appearance of electronic switches, which shows the great prospects of tact switches and micro switches. Our company is already a mature manufacturer and trader. , Has its own independent R&D center and factory, and laboratory personnel are always working hard in the process of design, R&D and improvement. Please look forward to the new transformation of the company.
