What is the Metal Dome and its Classification
Triangle Metal Dome : Generally , there an dimple on the center , or three dimples each side , in order to better fix at a certain position point, in addition, it can be divided into two types W/Feet or W/O Feet.
The Working Principle of Metal Dome
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
