According to the number of dimples, mental dome can be divided into 1 dimple, 3 dimples, 4 dimples( “Pin” font or “Kou” font)/5 points, and NIPPLE.- Concave point can improve the good contact between metal dome and the contact interface of main product, so as to achieve more stable Conduction effects.

-

Metal Domes with point have a bulge in the middle to the point, when connecting with circuit and dust entering, the dust will only bump around, and not bump on the effected area. In case there is dust on bulge, just press more times, so dust off and fragment automatically, effectively decrease the percentage of bad contact, to achieve the reliability of conduction.

-

(Therefore Metal domes with points are popularly and widely used now)- Circle series metal domes are mainly used for mobile phones, U disk, card reader, MP3/4, membrane switch, etc… Common specifications are between Φ3mm and Φ12mm, the force is in the range of 80G-500G. C-series metal dome have simple structure and less destruction in the process of punching, so life cycles is generally more than 100 million times. Because cell phones are mostly used C-series metal dome, it is also known as mobile dome.

-

Our metal domes has below chief advantages:
1.-Best elastic resilience: elastic tolerance within +-20g,
advantage of ± 30g than the industry
2.- Feel good: feel 40%-60%, can be adjustable according to clients' request.
