What is PCB with Metal Dome

Metal shrapnel (also known as pot or piece, metal dome, snap dome), made of ultra-thin (0.05mm-0.1mm thickness) and ultra-thick (usually high hardness) stainless steel 301 or 304 material. Metal dome is an important part of the dome switch pcb.

They are momentary switch contacts that become normally-open tactile metal dome switches when used in conjunction with a printed circuit board (PCB).

PCB is also known as printed circuit boards because it is made by electronic printing.  A printed circuit board is a substrate for assembling electronic components and is a printed board on which a point-to-point connection and a printed component are formed on a general-purpose substrate in a predetermined metal core printed circuit board design.

Metal domes can be divided into several groups: round metal dome, triangle metal dome,  rectangular metal dome, four-leg metal dome(cross shape), square shape metal dome and other special shapes. PCB membrane switches are widely applicable. It can be applied in areas including mobile phones, diagnostic equipment, industrial controls, test equipment, and measurement equipment, etc.
