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
Round Snap dome can be divided into below 3 types in accordance with dimple or not
1. Without dimple : NC series
2. Dimple in the center : DC series
3. With multiple dimple (usually three, four, five): SDC series
Round Metal Dome : it’s normally used in the electronic devices with small volume due to less space demand , also has good advantage in the feature of feels ,force and longer lifetime .
