There are many types of micro switches, and there are various application fields. Today, this article mainly introduces you to waterproof micro switches. For those who want to know the relevant information of waterproof micro switches, and if you need to buy waterproof micro switches people as a reference.
1、what is waterproof micro switch?
As the name suggests, a waterproof micro switch is a micro switch with a certain waterproof function.，Also called sealed micro switch.It is a pressure-actuated quick-change switch with other snap-action structures. It has special characteristics and the interval between the contacts is very small. The switch action is controlled according to the specified stroke and specified force. The waterproof micro switch is tightly covered with a casing. package, which has a kind of microswitch that actuates the lever on the outside.It can be used in water heaters, water dispensers, generators and other machinery. Many diving equipment also has the shadow of waterproof switches.
2.The purpose of waterproof micro switch
The size of the micro switch is small, but its function is very large, and we can see it everywhere in our lives. Such as computer mouse, car mouse, automotive electronic products, communication equipment, military products, testing equipment, gas water heaters, gas stoves, small household appliances, microwave ovens, rice cookers, floating ball equipment, medical equipment, building automation, power tools, etc.
3.The principle of waterproof micro switch
The external mechanical force acts on the action reed through the transmission element (press pin, button, lever, roller, etc.), and when the action reed is displaced to the critical point, an instantaneous action occurs, so that the moving contact at the end of the action reed and the fixed contact point to switch on or off quickly.
When the force on the transmission element is removed, the action reed generates a reverse action force, and when the reverse stroke of the transmission element reaches the action critical point of the reed, the reverse action is completed instantaneously. The contact distance of the micro switch is small, the action stroke is short, the pressing power is small, and the on-off is fast. The action speed of the moving contact has nothing to do with the action speed of the transmission element.
4.Wiring method of waterproof micro switch
When it comes to the wiring method of the micro switch, it is actually very simple. Generally, the micro switch has three points. One of these three points is the common point, the other is the normally open point, and the other is the closed point. The common point is like the one in the socket. The zero line, the normally open point is the point where the switch is opened so that the current flows, and the closing point is the contact that disconnects the current through. Just connect the corresponding point to the corresponding location. Although the micro switch wiring method is simple to open, it is still necessary to make relevant preparations in advance.

5.What are the advantages of waterproof micro switches?
·The first is reliable quality.
The country's requirements in the field of micro switches are very strict, which also makes manufacturers very meticulous in production, so customers will not be troubled by quality problems when using them, and manufacturers have a very complete after-sales system. , even if there is a follow-up problem, the manufacturer is the first to solve it for us.
·The second is adaptability.
Since it rains frequently in many places now, and the micro switches in the equipment must be waterproof, so the waterproof micro switches can still maintain high-intensity work in this rainy weather, and There will be no damage, which is unmatched by other types of micro switches. The important thing is that after the continuous optimization of technology, many waterproof micro switches have many other properties, such as fire prevention and short circuit prevention.
·The third is complete specifications and high selectivity.
Many waterproof micro switches are available in all sizes, and you can buy the model you want on the Internet, but if the size we want is not the current mainstream on the market, we can also ask the factory to customize it. The production of our equipment can be more accurate.
6.How to choose waterproof micro switch
With the advancement of science and technology, the upgrading of instruments and equipment, the waterproof micro switch is also constantly being updated in technology and materials.When choosing, it will consider many aspects such as size, weight, shape, material and so on.Especially for diving equipment or electrical equipment, it must be selected according to the actual application requirements, because in these applications, the discrepancy of some small parameters may cause serious accidents. The selection of the waterproof switch is based on different uses, and also needs to refer to different heat resistance, pressure resistance, and service life. These parameters can be referred to in the product manual.
Epilogue
Waterproof micro switches play an important role in many key aspects of production and life. Choosing the right one is very important for enterprises and individuals. Of course, some people feel that they are not professionals, do not know the knowledge of these switches, and do not know how to choose, then follow our simple idea and choose a large manufacturer with a good reputation, so that you can find a good quality switch relatively easily.
