Working Principle : The snap dome is located at the conductive part on the PCB (most of which is above the gold finger on the PCB). When pressed, the central dimple of the dome is concave and contacts the circuit on the PCB , Thus, the circuit is formed, and the current passes through, and the whole product can work successfully . With the help of the conductivity of the metal metal, it plays a role of high-quality switch between the operator and the product. The stable click ratio & longer life-time are used to provide the operator with high-quality tactile feel

The Cross Metal dome , also called 4 LEG snap dome ,  can be divided into below 4 types :

1. Dimple in the middle : DF Series
2. No dimple: NF series
3. There is a hole in the middle, which is rarely used
4. Four legs with feet, available when higher travel is needed

4-Legged Metal Dome : when designer reserve sufficient space & request bigger stroke travel , C-series metal dome will be prior to select to use , it’s often used in the handheld device、medical device and large banking equipment .

Metal Dome is mainly used for various key products、such as mobile phones、headphones、MP3 / MP4、all kinds of keyboard、remote control、bank Product keys、medical equipment、industrial instruments and other fields, where there are keys to use products, can use metal dome
