If you want to choose a good touch button switch, you must understand the principle.
If you want to choose a good touch button switch, you must understand the principle of touch button switch, so we will take you to see these knowledge today.
The light touch button switch is a very small and very sensitive spring-driven magnetic adsorption stroke switch. The light touch switch is a contact mechanism with small contact spacing and quick-acting mechanism, which operates with a specified stroke and force, and is covered with a housing. The outer part of the switch has a driving rod because of its small contact spacing and fast-acting mechanism. Switch contact spacing is relatively small, so the name of light touch switch, also known as sensitive switch, electrical text symbols are: SM, today, small edition for everyone to talk about light touch switch principle is what.
The external mechanical force acts on the action spring through the transmission elements (pin, button, lever, roller, etc.). When the action spring moves to the critical point, it produces instantaneous action, which makes the end of the action spring quickly connect or disconnect the dynamic contact and 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 action critical point of the spring, the reverse action is instantaneously completed. The contact spacing of the light touch switch is small, the action stroke is short, the power is small, and the switch is switched on and off rapidly. Speed has nothing to do with it.
The light-touch button switch has a small contact interval and a quick-acting mechanism. The contact mechanism operated by a specified stroke and force is covered by a housing. The outer part of the switch is a transmission and has a small light-touch switch. The following figure is an example of a typical light-touch switch structure. The light-touch switch consists of five major components.
Light touch button switches are used in many fields, such as computer mouse, automotive mouse, automotive electronic products, communication equipment, military products, test instruments, gas water heater, gas stove, small household appliances, microwave oven, rice cooker, float equipment, medical equipment, building automation, electric tools and general electrical and radio Equipment, 24 hour timer and so on.
Anyone who knows how to tap a switch knows that there are many classifications of switches on the market. For example, we often see ordinary switches, and there are 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 In a very clear way, the switch can be judged according to the shape when purchasing. Light touch switch is the most widely used switch. This kind of light touch switch is not the same as the general switch, because of its many types, and the specifications and sizes are very different, it is difficult to judge from the appearance. Its function is often puzzled when it comes to understanding this kind of touch switch.
The patch touch switch is one of them. The patch touch switch is now used more and more widely. It is used in many devices. This also confirms its diversity. We should know the quality of the patch touch switch before we buy the patch touch switch. It has good quality and bad quality, if we accidentally buy a poor quality light touch switch what to do, we will look at this problem together.
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 right way to buy so that you can buy a light touch switch in line with their own mind, in fact, there are some ways to buy patch light touch switch, the first way is to look at its quality, good quality light touch The switch is totally different from the ordinary light touch switch, because the material is very delicate, and will not have any rough place, because it is processed accurately, so the switch produced is very beautiful, the switch parts are also very good, such a switch is absolutely worthy of people to use, patch. Touch switch supply.
The second is to see 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 switches, see what light touch switches are different, if you know these different places then Knowing where a good touch switch hand feels better may be because the parts are more advanced, or because the production process is very advanced, so the production of a touch switch is very useful, such a touch switch is also very attractive.
The third method is to understand its size, generally speaking, the service life of the large touch switch is relatively low, because it has a high degree of wear and tear, it is easy to be worn, and the small touch switch because the volume is relatively small, so it is not easy to use the problem, it is not easy to appear too much wear and tear, so can For a long time, if you're familiar with the touch switch, you know it's pins. Every touch switch has pins, but their pins are different. They're basically made of different materials, preferably brass, which is not volatile and reduces contact resistance. So it's very safe. Phosphorus and copper light touch switches are also very good. This light touch switch is very similar to what we've been exposed to, and it's the most used one. The worst one should be iron, because iron is the most volatile and very important.
