Crown spring contact shrapnel is a mechanical part that uses elasticity to work. Generally made of metal shrapnel steel. It is used to control the movement of mechanical parts, alleviate impact or vibration, store energy, measure the size of force, etc. It is widely used in machines and meters. The types of hardware shrapnel are complex and diverse. According to the shape, they mainly include positive contact, power supply shrapnel, and contact mother shrapnel.
Crown spring contact shrapnel belongs to the category of metal stamping parts and electronic hardware materials. It is made of stainless steel or manganese after heat treatment. It is an important part of the switch. With the help of the conductivity of the metal shrapnel, it can play a high-quality switch between the operator and the product. At the same time, using the stable resilience of the guozi (automatically return after pressing), and the long life, provide the operator with high-quality tactile feedback!
The metal contact shrapnel is very flexible, mainly in the size and shape of the force. These three parameters can be changed according to the requirements of the product. (There must be a limit change).
The metal contact shrapnel has stability, elasticity and excellent conductivity. It is reflected in the low failure probability of electronic button products. Because it has good rebound strength, it is suitable for key switches of electronic products.
Metal contact shrapnel is very durable, stainless steel products are difficult to damage in principle, and surface treatment can extend the life of the workpiece.
The metal contact shrapnel parameters are obvious: such as life, strength, pressure resistance, even temperature resistance, cold resistance, etc., these parameters can be detected by testing equipment. It can also be designed according to the needs of the product. Of course, the better the performance, the more expensive the price. Therefore, customers are based on the actual needs of the product, not too much. For example, electronic button products are estimated to live for ten years, even if there is no mess in ten years. More than 300,000 times many times, so choosing 500,000 metal shrapnel is enough.
