What is the method to prevent excessive loss of micro-switch, and what is the specific operation method, the following will give you a detailed introduction.
The biggest technical feature of the design of micro-switch is to prevent loss and prolong its service life. The wear of micro-switch can be divided into wear and fatigue. The wear of micro-switch means the wear of contact surface or the loss of material. The fatigue of micro-switch refers to the generation of fatigue cracks or the decrease of fatigue life of metal and other materials.
1. Increasing the surface strength of contact elements is the main way to reduce the loss. Through various surface treatments, such as physical (laser, ion implantation and other hardening techniques to change the surface microstructure), chemical (carburizing, nitriding and other surface hardening techniques), mechanical (shot peening, rolling and other methods to increase the surface residual compressive stress), the material surface can obtain special composition, structure and properties, in order to improve its properties. Wear resistance and fatigue resistance. In addition, there are ways to enhance the electrical capacity of fatigue-prone metal reeds and contacts, such as using silver, alloy and other metal materials.
2. The structural design of micro-switch can also reduce the loss. For example, by changing the geometrical structure, clamping mode and contact size of components, as well as the pressure distribution and contact mode at the contact surface, fretting damage resistance can be improved to varying degrees. Another effective measure to reduce the loss of Dongguan micro-switch is to reduce the friction coefficient (friction), which can be achieved by increasing the lubricating medium.
