First, the overview of micro switch
A microswitch is a commonly used electrical switch, also known as a limit switch. It realizes circuit opening and closing through mechanical structure and electrical contacts, and is widely used in home appliances, electronic equipment, automation control and other fields. Micro switch has the advantages of compact structure, sensitive contact, long service life, etc., and is widely used.
Second, the common micro switch model
1. Z-series
The Z Series microswitch is a common model, which has a smaller size and a longer life, and can be used in mechanical and electrical equipment. The Z series can also be divided into single and double blade models to meet the needs of different applications.
2. D2FK series
D2FK series micro switch is a general purpose model, mostly used in electronic equipment. It is available in several different operating forces and assembly forms. D2FK series microswitches can work in harsh environments, such as high temperature and high humidity.
3. V-15 series
The V-15 series microswitches are a highly sensitive model with several different trigger forces to choose from. It has a long life and can be used millions of times. The V-15 series microswitches can be used in home appliances, automation control and other fields, and are widely used in applications requiring high sensitivity and long life.
Third, the selection method of micro switch
The selection method of microswitch mainly includes the following aspects:
1. According to the application to determine the parameters, such as rated voltage, rated current, trigger force, action mode, etc., these parameters in different applications are not the same.
2. According to the reliability and life requirements to determine the model, different models in the life and reliability of the different, according to the actual needs to choose the appropriate model.
3. Refer to the performance curve and data manual provided by the manufacturer, which is of great help for selection, and the advantages and disadvantages of different models can be compared according to the performance curve and data manual.
4. Compare the micro switches provided by different manufacturers. Before selection, we need to understand the performance and price of different manufacturers, and choose the right supplier after comprehensive comparison.
