Touch the button switch in the use of what needs to know, we will give you a detailed introduction below.
The light touch button switch is a spring-driven magnetic adsorption stroke switch with small size and very sensitive. The light touch switch is a contact mechanism with small contact interval and fast-acting mechanism. It operates with a specified stroke and force. It is covered by a shell. There is a switch with a driving rod outside. Because the contact spacing of the switch is relatively small, the light touch switch is named as the light touch switch. It is also called sensitive switch. The electrical symbol is SM.
The external mechanical force acts on the action reed through the transmission elements (pins, buttons, levers, rollers, etc.). When the action reed moves to the critical point, it produces instantaneous action, which makes the dynamic contact at the end of the action reed connect or disconnect quickly with the fixed contact.
When the action force on the transmission element is removed, the action spring produces the reverse action force. When the reverse stroke of the transmission element reaches the critical point of the action of the spring, the reverse action is completed instantaneously. The contact distance of the light touch switch is small, the action stroke is short, the action speed of the moving contact is small, and the on-off speed is fast. The action speed of the moving contact has nothing to do with the action speed of the transmission element.
The light touch button switch has a small contact interval and a speed mechanism. The contact mechanism operates with the prescribed stroke and force is covered by the shell. The outer part of the switch has a drive, and the shape of the switch is smaller. The figure below is an example of the typical light touch switch structure. The light touch switch consists of five major components.
The light touch button switch is used in many aspects, such as computer mouse, automobile mouse, automobile electronic products, communication equipment, military products, test instruments, gas water heater, gas stove, small household appliances, microwave oven, rice cooker, floating ball equipment, medical equipment, building automation, electric tools and general electrical and radio equipment, 24-hour timer, etc.
People who know about light-touch switches know that there are many kinds of switches in the market, such as ordinary switches that we often see, and professional switches that we seldom touch. These different types of switches have different functions. Basically, these different types of switches have different shapes. We can clearly judge the style of switches from their shapes. When purchasing, we can also judge according to the shape. Touch switch is the most widely used one at present. This kind of switch is not the same as the general switch. Because of its many types and different specifications, it is difficult to judge its function from the appearance, so we are often confused when we understand this kind of touch switch.
The patch touch switch is one of them. Now the patch touch switch has been used more and more widely. It is used in many equipments, which also proves its diversity. Before we buy the patch touch switch, we should know the quality of the patch touch switch. It has good quality and bad quality. What should we do when we accidentally buy a light touch switch with poor quality? Let's take a look at this problem.
In fact, it is not difficult to purchase a good touch switch, the key is to see how you choose, as long as you know the correct purchase method, then you can buy a touch switch in line with your own mind. In fact, there are some ways to buy a patch touch switch. First of all, one way is to look at its quality. A good touch switch is totally different from a general touch switch. Because its material is exquisite, and there will be no rough place, because it is precisely processed, so the switch produced is very beautiful, the various parts of the switch are also very good, such a switch is absolutely worth people to use, patch light touch switch supply.
The second is to look at the use of touch switch feel, good touch switch feel must be very good, we can pick up when selecting, compare these different types of touch switch, see what they have different touch switch, if you understand these different places, then you know where the good touch switch feel better. Yes, it may be because the parts are more advanced, or because the production process is very advanced, so the light touch switch produced is very useful, such a light touch switch is also very attractive.
The third way is to know its size. Generally speaking, the service life of large lightly touched switches is relatively low, because of its high wear and tear, and small lightly touched switches are easy to wear, because of their small size, so they are not easy to cause problems in use, nor are they easy to wear too much, so they can be used for a long time if you touch the lightly touched switch ratio. If you are familiar with it, you must know its pins. Every touch switch has pins, but their pins are different. They are basically made of different materials. The best material is brass. This material is not easy to volatilize and can also reduce the contact resistance. So it is very safe. The touch switch of phosphorus copper is also very good. This touch switch contacts us. It is very similar, and the most used, the worst should be iron, because iron is the most volatile, and easy to oxidize, so we try not to buy iron pin touch switch.
