Choosing a good touch button switch is not difficult, as long as you can understand these contents can easily choose to touch the button switch, the specific method described below for you.
The light touch button switch is a kind of magnetic adsorption stroke switch driven by a very small size and very sensitive spring. The light touch button switch is a kind of contact mechanism with a small contact interval and a quick-acting mechanism, which uses a prescribed stroke and a prescribed force for switching action. It is covered with a housing and has a driving rod outside. For its switch contact spacing is relatively small, so the name of touch button switch, also known as sensitive switch, electrical text symbols: SM, today, small edition for everyone to talk about touch button 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 distance between the touch button switch is small, the action stroke is short, the power is small, and the switch is swift to turn on and off. Action speed is independent.
The light touch button switch has a small contact interval and a quick-acting mechanism, and a contact mechanism operated by a specified stroke and force is covered by a housing. The outer part of the switch is driven by a small light touch button switch. Factor composition.
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 button knows that there are many kinds 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 clearly judge the style of the switch from the shape, and we can also judge it according to the shape when we buy it. The light touch button switch is the most widely used. This kind of light touch button switch is not the same as the general switch, because there are so many types, and the specifications and sizes are very different, we are very difficult. Judging from its appearance, it often puzzles you when you understand this touch button switch.
One of them is the patch touch button switch. Now the patch touch button switch is used more and more widely. This kind of touch button switch is used in many devices, which confirms its diversity. We should know it before we buy the patch touch button switch. The quality of the touch button switch is good or bad. It has good quality and bad quality. What if we accidentally buy a touch button switch with poor quality? Let's take a look at this problem together.
In fact, it is not difficult to purchase a good touch button switch, the key is to see how you choose, as long as you know the right way to buy the button switch can be bought in line with their own mind touch, in fact, there are some ways to buy patch touch button switch, the first way is to see its quality. A good quality light touch button switch is completely different from a normal light touch button switch because it is made of exquisite materials and does not have any rough places, because it is precisely processed, so the switch produced is very beautiful, the various parts of the switch are also very good, such switch absolute value People have to use the patch touch button switch to supply.
The second is to look at the use of touch button switch feel, good touch button switch feel must be very good, we can pick up when selecting, compare these different types of touch button switch, see what they have different touch button switch, if you understand these different If you're in the right place, you know where a good touch button switch hand feels better. Maybe it's because the parts are more advanced, or maybe it's because the manufacturing process is very advanced. So the touch button switch is very useful, and the touch button switch is very attractive.
The third method is to understand its size, generally speaking, the service life of the large touch button switch is relatively low, because of its high degree of wear and tear, it is easy to be worn, and the small touch button switch because the volume is relatively small, so it is not easy to cause problems in use, it is not easy to appear too much wear and tear. So it can be used for a long time, if you're familiar with the touch button switch, you know its pins, every touch button switch has pins, but their pins are different, basically made of different materials, preferably brass, this material is not volatile, but also Enough to reduce contact electricity
