A tact switch is a kind of electronic switch in the category of electronic components. It has the advantage of being small in size and lightweight with high sensitivity and consuming less power in the circuit. Therefore, tact switch is widely used in white goods, automobiles, medical care, 3C products, industrial machinery, ships, aviation, and other fields. The following is a brief introduction to tact switches from two aspects.
I. Development prospects of tact switches
Consumers around the world are increasingly preferring electromechanical technology over traditional manual switches when operating various devices and equipment, which is driving the rapid growth of the tact switch market. Currently, many developing and developed regions have seen great potential in the tact switch market, major regions including Europe, North America, Asia Pacific, the Middle East, Africa, and Latin America. Among these, Asia Pacific has shown significant revenue potential to other players in the tact switch market. Growing sales of low-energy consumer electronics and widespread use of information devices have helped the region to gain a significant position in the global tact switch market in the past few years.
From the view of the region, the Chinese market is changing more rapidly. In the last two years, the total demand has been much larger than a billion units. At the same time, the growth of membrane switches has exceeded more than 100%, and the demand for push-button switches ranks first in Asia. The production base of tact switch products is widely distributed, and the design and quantitative production can be completed in all regions. Although most of the companies are small in size, they can produce products in fairly quick turnaround times, with volume deliveries in less than a month. Meanwhile, these enterprises are also qualified to produce other related products, such as micro switches, push-button switches and connectors, and several other major categories of products. On the other hand, the problems of mold manufacturing, new product development, lead-free and environmental plating can now be solved, and there are quite some enterprises that have passed the ISO9001:2000 quality management system certification.
At present, the tact switch is becoming more and more mature in technology, and the price of the product is very competitive in the market. A part of the products have the price advantage and high reliable performance, which can meet the supporting needs of customers at home and abroad. Nowadays, the production enterprises of these products are mainly concentrated in the Yangtze River Delta and the Pearl River Delta region. As we all know, the two river deltas are strategically located and economically developed, and are important commodity trading areas in China. This makes the import and export trade of light contact switches more convenient, and the market can be broadened and expanded.
It can be seen that in the next five to ten years, the market for tact switches will continue to expand, and the development prospect is very considerable.
II. Types of the tact switch
Tact switches are mainly divided into three categories in the market: tact switch with LED, waterproof tact switch and normal tact switch.
1. Tact switch with LED
At present, there are two main types of tact switches with LED: single-color LED and multi-color LED. Tact switches with multi-color LED can be used with two-color lights, and three-color lights, loaded into electronic products for indicators, lighting, and logo lighting purposes. Tact switches with Single-color LED can be divided into the front-illuminated type and side-illuminated type. They come in a variety of sizes and should be selected according to their specific purpose.
Specification
Rated load | DC12V 50mA MAX;DC5V 0.1mA MIN |
Contact resistance | ≦100 MΩ |
Insulation resistance | ≧100 MΩ |
Temperature | -20℃~70℃ |
Operating force | 160±50gf / 250±100gf |

2. Waterproof tact switch
The waterproof membrane is sealed between the waterproof membrane and the base of the product, which can effectively prevent dust and water from entering and contacting with the reed, improving the reliability and service life of the product. IP67 level tact switches are dustproof and waterproof, and they are widely used in air conditioners, washing machines, and other home appliances.

3. Normal tact switch
General tact switches are available in front push-type, side push-type, SMD type, pin type, equilateral standard type, etc. They are rich in variety and suitable for communication equipment, home appliance equipment, automotive equipment, industrial machinery processing machine tool operation panel, etc.

In general, technology is a product of the times, with a single click, we can immediately start a variety of products. The emergence of tact switches allows more and more electronic products into the “light-touch” era. It is a multi-service society nowadays, so the tact switch should not only be long-lasting and reliable but also comfortable and smooth to give consumers a satisfactory experience. I firmly believe that the technology of tact switches will become more and more advanced, bringing more convenience to human life in the near future.
