Micro switch is a commonly used electronic component, which can sense the small movement of an object and convert it into an electrical signal. It is often used in switch control, circuit unlocking, mechanical induction and other occasions in electronic products. When selecting a micro switch, it is necessary to consider the use environment as well as the required performance and characteristics to ensure that the appropriate micro switch is selected to achieve the desired control effect. First of all, the use environment of the micro switch needs to be considered. For example, if the micro switch needs to work in a humid environment, a micro switch with waterproof performance should be selected. If the micro switch needs to be used in a high temperature environment, a high temperature resistant micro switch should be selected. In addition, micro switches used in vibration or shock environments must also have sufficient mechanical strength to ensure that they are not damaged. Secondly, the performance and characteristics of the micro switch need to be considered to meet the required control requirements. For example, the rated current, rated voltage, contact resistance, contact material, contact gap and other parameters of the micro switch need to be considered. Choosing micro switches with different characteristics will also affect the use effect. For example, you need to choose a micro switch that is momentarily open or momentarily closed. In addition, when selecting a micro switch, its service life and reliability also need to be considered. High-quality micro switches can continue to work in harsh environments and maintain their reliability and stability. In conclusion, choosing the right micro switch plays a very important role in controlling and sensing motion in electronic products. When selecting a micro switch, key factors such as the use environment, characteristics, and reliability need to be considered to ensure that the appropriate micro switch is selected to meet the control requirements and ensure stable performance of the device. For novices, it is a wise choice to choose a brand with reliable quality. At the same time, you need to read the product manual carefully to ensure that you have enough professional knowledge to select and use the micro switch.
