The light touch switches that we learn in everyday life are called button switches, yet the earliest place where they appear is in japan, where we use four feet to touch the switches in such a way that we are able to apply pressure on the switches to perform the opening and closing functions. In accordance with its working principles and the use of its application, we are able to have a comprehensive understanding and mastery of the four-legged light-touch switch so that, in its application, we can maximize its merits. The following is a brief introduction to the working principles, attention, scope of application and selection methods of the four-legged light-touch switch. Details are as follows:
1. The working principles of the four-legged light touch switch
The working method of the four-leg light-touch switch is similar to that of the general button switch, which is a combination of constant contact points and frequent contact points, and in the four-leg light-touch switch, the effect of a frequent contact point is that the circuit becomes connected when pressure is pressured to the frequent contact point; when the pressure was lifted, it was restored to the initial contact point, the so-called disconnection. And this pressure, it's using our hands to turn off the buttons and turn them on. So, the four-legged switch works well to understand and understand。
2. Care to use a four-legged light touch switch
In the case of welding of switches, the conditions at the time of production need to be confirmed. Because of the different conditions and the compatibility of the endpoints, deformation is also possible and this must be taken into account in the process of use. With regard to the thermal stress effects of the four-leg light touch switches, adequate confirmation must be prepared before they are applied; the two welding processes must return to a second welding in a normal state after the first welding, with effects on the outer shape of the four-leg light touch switches if heated continuously, and the end is likely to fall, leading to a decrease in electrical properties. The electrical resistance load of the four feet to the switch is designed in such a way that, when other loads are used, be careful to confirm。
3. Scope of application of four-leg light touch switches
We have also briefly described the application range of four-leg light touch switches, such as electrical wind, electrofat scales, television sets, microwave ovens, rice cookers and electronic kitchen scales in home appliances; monitors, visual walkiephones, etc. In secure products; tape pens, cameras, etc. In computers; sphygmomanometers, call systems in medical equipment, body thermometers, etc., massage chairs in fitness equipment, running machines, etc., in which four feet of light touch switches are used. There are many other aspects, but we can also see from the application of the four-leg switch that it will be more widely used in future developments。
4. Selection method for four-foot light touch switches
In selecting switches, the good or bad of switches will directly affect the use of products. Therefore, when choosing a four-leg light touch switch, weldability, guidance, etc. Should be sensitive to the physical properties of the four-leg light touch switch, whether the touch is rough or not, and the useful life is long and these external surface factors will determine the quality of the four-leg light touch switch。
The above four elements will briefly describe the performance and use of the four-leg light-touch switches, so we should be careful, both in their use and in the selection process, so that we can benefit from the use of the four-leg light-touch switches and create quality security for our work and lives。
