The button is one of the indispensable one kind of accessories of electronic products, in the early 80’s has been applied in electronic components, silicone button is used to connect or disconnect control circuit, the control of the electric current is very small, it can achieve low current effect and applied to the current many electronic remote control and switch of electric equipment,

 

In the early days, the materials of buttons were mainly customized by plastic, ABS, PBT, POM and other materials. With the development and upgrading of industrial technology, silicone rubber products were gradually transformed from military to civilian, and button products were gradually accepted by consumers. As one of the indispensable accessories in the electronic industry, they are widely used in calculators, telephones, Electronic toys and learning machine silicone keys, electronic digital keys. 

 

In the early 90s with the development of industrial technology progress and manufacturers began to rise, make a lot of silicone buttons to process exploration research, from the beginning of the conductive black grain to spray coating conductive ink, from the beginning of the monochrome printing gradually developed to fill oil process, from monochrome to multi color secondary molding process, molding development make silicone products industry began to rise gradually, hence More and more silicone rubber button processing plants to small workshops, small scale gradually grow to formal integration molding. 

 

And silicone buttons up to now are able to get the advantages of using main advantage lies in the material market is more outstanding, shovel art gradually simplified, the market price also began to gradually clear, and it's advantage is more, the silicone buttons material resistant to high and low temperature performance is good, not easy to any material, no ignition burning, etc., And non-toxic and tasteless, the material is relatively soft, and green environmental protection is its real theme, so it is widely used in life. 

 

In addition to the material, the functional life of the silicone button is also outstanding, the normal service life can be up to three million times, the load pressure is about 40 to 500 grams, Contact resistance less than 150 ohms, silicone material elastic number not less than 1.8 million times, of course, the requirements of data tests are carried out in accordance with the industry standard silicone buttons to choose, for the choice of silicone material tensile test and resistance of the ink has certain correlation, and basic functional can completely conform to the normal use of most of the electronic products to an end of life.
