The working principle of four legs metal dome

The four legs metal dome is located on the conductive part of the PCB (mostly located above the golden fingers on the PCB). When pressed, the central recess of the dome will be recessed and contact with the circuit on the PCB, thereby forming a circuit, and the current will pass, the whole product can work normally. With the help of metal conductivity, it plays a high-quality switch between the operator and the product. Stable click rate and longer service life can provide operators with high-quality touch.
