Metal shrapnel (also known as a metal dome, snap dome) is made of ultra-thin (0.05mm-0.1mm thickness) and ultra-thick (generally higher hardness) stainless steel 301 or 304 materials. The metal dome is an important part of the switch. Metal shrapnel is mainly used in membrane switches, contact switches, PCB boards, FPC boards, medical equipment, and other products.

The working principle of the metal shrapnel: the metal shrapnel 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 circuit on the PCB, so as to form a loop, the current passes through, and the whole product can work normally.
