There are many kinds of microswitches and hundreds of internal structures. There are ordinary, small and super-small integrals by volume. According to the protection performance, there are waterproof, dustproof and explosion-proof types; According to the form of disconnection, there are single connection, double connection and multiple connection. There is also a powerful disconnect microswitch (when the reed of the switch does not work, external force can also close the switch); According to the breaking capacity, there are common type, DC type, micro current type and large current type.

　　According to the use environment, there are ordinary type, high temperature resistant type (250 ℃) and ultra-high temperature resistant ceramic type (400 ℃). The general microswitch is based on the accessory without auxiliary press, which derives the small travel type and the large travel type. Different auxiliary pressing accessories can be added as required. According to the different press accessories added, the switch can be divided into button type, reed roller type, lever roller type, short arm type, long arm type and other forms. There are small, super small and super small in size, and waterproof in function. The common application is mouse button.
　　(1) Miniature microswitch: the general dimensions are 27.8 in length, 10.3 in width, and 15.9 in height. The parameters vary with high capacity and low load.
　　(2) Micro microswitch: generally 19.8 long, 6.4 wide and 10.2 high, with different functions of high precision and long life.
　　(3) Ultra-micro microswitch: the general size is 12.8 long, 5.8 wide, and 6.5 high. This type has ultra-thin design.
　　(4) Waterproof.
　　The design principle of microswitch is very different from that of ordinary switch, and the requirements and details in use seem to be different. So, what is the function of microswitch? It is still necessary to make corresponding analysis from different perspectives to ensure that the role of all aspects will become better and better.
　　1. The control mode is novel. The switch can be realized by sound or touch without manual operation. This control mode reduces the wear phenomenon inside the switch to a certain extent. Therefore, the switch control performance will be more unique, and the superior performance will be better, so that you can feel more comfortable in the process of use.
　　2. The operation requirements are simple and easy to learn and operate. This is also the reason why the microswitch can achieve such excellent results after improving the technical principle. So when we analyze the function of the microswitch, we will find that the operation is constantly simplified, which will be more convenient and efficient to use.
　　3. Realize the function of accurate control without failure. Compared with traditional switches, in fact, the micro-switch control is more accurate and reliable, and there will be no fault, and even the operation requirements will be more strict, so it will be safer and more reliable in the process of use, so only through comparative analysis can we know that their functions will still be different.
