Before understanding the development and evolution of touch switch, let's find out what is touch switch?
It is generally called a small touch switch or a light touch switch in the industry, which is generally called a certain stroke. Light touch switch is widely used in electronics, home appliances, automobiles, military industry, medical treatment, robotics, industrial automation and other fields.
When it comes to the development history of light touch switch, it is naturally necessary to divide it into generations, from large to small according to its size; The service life ranges from short to super long (1000, 10000, 100000 and million); Materials and processes are from simple to complex (phosphor copper, stainless steel, polymer materials, laser technology, nanotechnology); So far, it can be roughly divided into four generations.
First generation touch switch
The mainstream dimensions are 12 * 12mm and 8 * 8mm, the dimensional tolerance is plus or minus 0.1mm, and the service life is 3000-8000 times. After improvement, there are more than 30000 times, which has a history of more than 30 years.
Second generation light touch switch
The mainstream size is 6 * 6mm, 4.5 * 4.5mm, the dimensional tolerance is plus or minus 0.1mm, the service life is 30000-50000, and the improved version can reach 50000 times.
Third generation touch switch
With the rapid development of science and technology, more and more small devices come into life. The light touch switch begins to develop in the direction of smaller volume and more compact structure. Representative dimensions of the third generation switch: 3 * 6, 2 * 4, etc. The general service life is more than 50000 times, and the scope and quantity of applications are more extensive. It can be seen that this generation of switches mainly develop to SMT chip.
Fourth generation touch switch
From this generation, the light touch switch has obviously developed to light and thin, and is more applied to 3C products. Compared with the previous two generations of switch products, the height of the third generation mainstream is controlled at about 2mm, representing products of 4 * 4 * 1.6mm and 3 * 6 * 2.5mm.
Fifth generation touch switch
The rise of smart phones, cameras, Bluetooth headsets and home medical instruments has led to the further improvement of the market requirements for touch switches. Higher service life, waterproof and stability; The demand for ultra-thin has been put forward. Automatic production, laser packaging technology, nanotechnology and polymer film materials have become the production process of light touch switch. It can be said that the fifth generation light touch switch is a qualitative leap. At the same time, it also puts forward higher requirements for raw materials, production technology, quality control and automation technology. Representative switch: Classic Series 3 * 2 * 0.6mm, 2.8 * 1.9mm0 6. 2.6 * 1.6 * 0.55mm. It can be seen that the height is controlled within 1mm, the service life is more than 500000 times, and the waterproof grade has reached IP68.

Sixth generation touch switch?
Here, we dare not say that there will be the sixth generation of touch switch products. With the current materials and production technology, combined with the consideration of cost, there will be no new generation of touch switch in the short term. It is unknown whether graphene will become the material of the next generation of switches in the future. With the continuous emergence of new materials, I hope better switches will be applied. Perhaps 3D touch, face recognition and fingerprint recognition will become the mainstream. Welcome to leave a message.
