Working principle of cross-shaped precision shrapnel

Precision Electronic Technology Co., Ltd. is located in Dongguan City, Guangdong Province. The company was established in 2008. It mainly produces and processes shielding covers, precision shrapnel, hardware terminals, and precision stamping parts. The company can integrate design, production, and processing according to customer requirements, and can also customize according to customer requirements. In line with the business philosophy of integrity, excellence, harmony and innovation. The precision shrapnel of the cross-shaped series is a four-leg shrapnel, referred to as a cross-shaped shrapnel, also called a four-corner shrapnel. Due to the characteristics of its own structure, the cross-shaped shrapnel has a very good feel, high stroke, and long life (1 million times). It is mainly used in membrane switches and control panels, so it is also called membrane switch shrapnel. Widely used in single and double-sided, multi-layer hard boards (PCB), flexible circuit boards (FPC), controllers, etc. The cross-shaped shrapnel on the membrane button is located on the conductive part of the PCB board (mostly located above the golden fingers on the circuit board). When pressed, the center point of the shrapnel is concave and touches the circuit on the PCB, thus forming a loop. When the current passes, the whole product can work normally. The precision shrapnel processing material is stainless steel, which is an important part of the switch. With the help of the conductivity of the shrapnel, it acts as a high-quality switch between the operator and the product. At the same time, the stable resilience of the guozi (automatically return after pressing) and the long lifespan provide the operator with high-quality tactile feedback. The workpieces are mainly used in membrane switches of rigid boards such as printed circuit boards. Precise contact information: Precise wish you all a prosperous business and all the best.
