If we want to use the four foot light touch switch, we must select a high quality four foot touch switch. How should we choose it? The following will be taught in detail.
The light touch switch that we know in our daily life is also called the button switch. However, the earliest place of this switch is in Japan. When we use four feet to touch the switch, we pressure the switch to meet the operating force, in order to open and close the switch. According to its working principle and application range, we can have a comprehensive understanding and mastery of the four foot touch switch, so that we can use it in the process of using its advantages to the extreme. Next, Xiaobian briefly introduces the working principle, matters needing attention, application scope and selection methods of the four foot light touch switch. The details are as follows:
Selection of 1, four foot touch switch
In the process of selecting switches, the quality of switches will directly affect the use of products. Therefore, when we choose the four foot touch switch, we should pay attention to the physical properties of its protective, weldability and conduction, whether the touch is rough, the service life is long, and the external surface factors will also determine the quality of the four foot touch switch.
The application range of 2, four foot touch switch
We also briefly introduced the applications of four foot touch switches, such as electric wind, electronic fat scales, TV sets, microwave ovens, rice cookers and electronic kitchen scales in the field of household appliances; the monitor in the security products, visual interphones, and so on; the recording pens and cameras in the computer; the sphygmomanometer and medical equipment. Such as call system, thermometer, massage chair and running machine in fitness equipment, etc. There are many other aspects, however, from the application scope of the four foot touch switch, we can see that this kind of switch will be more widely used in the future development process.
3, four feet light touch switch use attention
As for the welding of switches, it is necessary to confirm the conditions of production. Because of the different conditions, the application of terminals, deformation and deterioration are also possible, so we must pay attention to this point in the process of using. The thermal stress effect on the four foot touch switch should be fully prepared before the application. The two welding process must be restored to the normal temperature after the first welding, and second times of welding. If continuous heating, it will affect the shape of the four feet touch off the close and the terminal is also possible. It will fall off, resulting in a decline in electrical properties. The resistance load of the four foot light touch switch is well designed. When using other loads, please pay attention to the confirmation.
The working principle of 4, four foot touch switch
The working principle of a four foot touch switch is in fact similar to the working principle of the general button switch, which is composed of often closed and often open contacts. In the middle of a four foot touch switch, the function of the contact is often opened. When pressure is pressed to the constant contact point, the circuit will be on the state when the pressure is cancelled. It is restored to the original normally closed contact, which is called disconnection. The pressure is to use our hands to close the button and open the button. Therefore, the working principle of the four foot light touch switch is still well understood and recognized.
