Dome chips on mobile phones are widely used products. They are generally composed of rings and waist circles. Naturally, with the necessity of design schemes in recent years, it is also found that some triangle and cross shapes occur in mobile phone software, but basically It is rare to see this.

Generally, there are only two types of dome chips on mobile phones without grooves and grooves (one point), but with the necessity of research methods and design plans, the measures are not effective. In 2009, there were many 3 grooves and 4 grooves. 5 grooves come together. A little more pot on the mobile phone can make the touch characteristics of the product more flexible and dexterous, but its service life will be slightly lower than that of a groove. All in all. There are pros and cons

The diameter of the ring is generally 3MM, 3.5MM, 4MM, 4.5MM and 5MM. The waist circle: 5.0*3.7MM, 4.0*3.0MM and 4.5*3.3MM. Naturally, the similar diameter of 4.5MM is what our company needs from customers. The design scheme and research method within the scope are more suitable for mobile phones with smaller indoor space.
