The metal shrapnel belongs to the metal stamping parts, and is in the category of electronic hardware materials. It is made of stainless steel or manganese material after heat treatment. It is an important part of the switch. By virtue of the conductivity of the metal spring, it plays a high-quality switch role between the operator and the product. At the same time, the stable elastic force (active return after pressing) and the long service life of the pot piece are used to provide the operator with high-quality tactile response.
The production of metal shrapnel is a special process of processing materials (metal or non-metal) into parts (or semi-finished products) through cold stamping of stamping dies. Stamping is a kind of pressure processing method that uses the die installed on the press to apply pressure on the data at room temperature to make it separate or plastically deform, so as to obtain the required parts.
The elastic piece is a metal component in the thin film switch, which is widely used. At present, many products have a disorder in the use of shrapnel, especially in the flexible circuit, which is only used as an element to supply the hand feeling (tactile response), resulting in many disadvantages to the function of the membrane switch, and even the membrane switch loses its due role.
