Professional production and supply of wholesale micro-switch Mini Slide Switch, complete specifications and models, provide drawings download, parameters and picture understanding. The key to the quality of micro-switch lies in the production process, factory inspection, quality depends on whether it has protective, solderability, reliability of conduction, life, and device size and other factors. What problems should be paid attention to in the production process of micro-switch?
Production process of micro-switch. The final impact on quality is assembly process after having accessories. Assembly process depends on the management ability of manufacturing enterprises, production personnel and quality assurance ability. The final product quality can be different with different guarantees. Now there are manual and machine assembly methods in the market. Because of the current automation, the final product quality can be re-determined. In the process of upgrading, there are advantages and disadvantages: low cost of machine assembly but low quality of goods, high cost of manual assembly but high quality.
Firstly, the pin base material is the pin base material, and the pin base material of the micro-switch is brass or phosphorus copper (high grade is iron). In order to reduce the contact resistance, the pin is treated with silver plating at the root. SO2 in the air is oxidized, which indirectly affects the solderability and contact resistance of the switch. Therefore, the high-quality switch should first be on the pin. The thickness of silver plating and silver plating process of the base material should be controlled in place. Whether the base material of the micro-switch can stop the disposal of maintenance agent after silver plating or whether the switch has the function of dust-proof and water-proof is very important, otherwise, even if the switch is well disposed of by silver plating, the switch will be oxidized.
Secondly, the key factor affecting the reliability of conduction fastness is the structure of contact points. Since the function of the switch is to stop contact and conduction between contact points and shrapnel, the larger the contact surface of contact points, the better the contact surface is. The contact surface is determined by the structure.
Service life of micro-switch. The life of micro-switch is decided by the stroke of switch and the matching of shrapnel. The shorter the stroke, the lighter the sound, the longer the life, and vice versa. In a fixed shrapnel process, the life of switch depends mainly on the stroke or sound resolution. In addition, the key factor of the life of shrapnel is stamping technology.
Factory inspection of micro-switch. This project is also a key step affecting quality, such as appearance, feel, conduction, resistance and other items are spot checked or full checked, for example, the reject rate required by some large factories is weighed by PPM or zero defects, it is necessary to set up spot checks or quality checks after full checks are set up in factory inspection.
