The function and classification of Metal dome

Metal dome is a component made of ultra-thin (0.05mm-0.1mm thickness) and superhard (generally between HV480-550 hardness) stainless steel material, mainly used in products such as film switches, micro switches, PCB boards, printed circuit boards, and rigid boards. Guozi tablets have good conductivity, serving as a high-quality switch between the operator and the product. They also have stable rebound force and a long lifespan, providing the operator with high-quality tactile feedback. In addition, the pot pieces can undergo various surface treatments such as nickel plating, silver plating, and gold plating to meet the needs of different product structures and grades

The classification of Metal dome mainly includes:

Metal spring plate: This is the basic form of pot plate, made of stainless steel, and is an important component of the switch. Through the conductivity and stable rebound force of the metal spring plate, it plays a high-quality switching role between the operator and the product.

Button spring: also known as pot piece or metal dome, snap dome, made of ultra-thin and ultra thick stainless steel 301 or 304 material, is an important component of switches

Mobile phone shrapnel: The shrapnel under the phone buttons, divided into primary and side keys, has a certain curvature, with the convex surface facing up and the concave surface facing down, which contacts the PCB/FPC board and plays a conductive role between the adhesive button and the bottom circuit board.

Metal dome Conductive Film: or Metal Bullet Film, is a PET sheet containing metal bullet (Metal dome), used as a switch on PCB or FPC circuit boards, playing an important tactile switch role between the user and the instrument

Surface treatment cookware: A surface treatment equipment that forms a coating by high-speed spraying of melted powder materials, which can be used for surface treatment and repair of various materials such as metals, ceramics, plastics, etc. This includes metal pot pieces, ceramic pot pieces, and plastic pot pieces.

In summary, metal dome not only plays an important role in the activation and control of electronic products, but also provides a high-quality user experience through its unique physical characteristics. At the same time, according to different application requirements, cookware pieces can undergo diverse surface treatments and classifications to meet the design and functional needs of various electronic products
