Among metal stamping parts, metal shrapnel is a product that we use more. It is an important part of the switch, with the help of the conductivity of the metal shrapnel, it acts as a high-quality switch between the operator and the product.
The working principle of metal dome stamping: The metal dome stamping on the membrane button is located on the conductive part of the PCB (mostly above the gold fingers on the circuit board). When pressed, the center point of the shrapnel is concave and contacts the PCB. Circuit, thus forming a loop, the current passes through, and the whole product can work normally.
