What is the performance of the four-legged touch switch we use? In order to help you understand the four-legged touch switch better and faster, we give you the following introduction, please know and understand more.

Touch switch, also known as button switch, but the earliest place of this kind of switch is in Japan, when we use four feet touch switch, in order to meet the operating conditions, to pressure the switch, thus to carry out the function of opening and closing. According to its working principle and application scope, we can have a comprehensive understanding and grasp of the four-legged touch switch, so that we can make its advantages to the extreme in the process of application.
1. Application scope of four-legged touch switch
We also briefly introduced the application scope of four-legged light touch switch, such as electric wind, electronic fat scale, television, microwave oven, rice cooker and electronic kitchen scale in household appliances, monitor in security products, visual walkie-talkie, recording pen and camera in computer, blood pressure meter, call system in medical equipment, thermometer, fitness equipment, etc. Massage chair, running machine, etc., these areas, four feet touch switch are involved in the application. There are many other aspects, however, from the application scope of the four-legged touch switch, we can also see that this switch will be more widely used in the future development process.
2. Working Principle of Four-legged Touch Switch
In fact, the working principle of four-legged touch switch is similar to that of ordinary button switch. It is composed of normally closed contacts and normally open contacts. In four-legged touch switch, the function of often open contacts is that when the pressure is applied to the normally open contacts, the circuit will be turned on; when the pressure is removed, the original normally closed contacts will be restored, that is, normal closed contacts. The so-called disconnection. This pressure is the action of closing and opening the button with our hands. So, the working principle of the four-legged touch switch is well understood and recognized.
3. Selection Method of Four-legged 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-legged lightly touch switch, we should pay attention to its protection, solderability, conduction and other physical properties, rough touch, long service life, these external surface factors will also determine the quality of the four-legged lightly touch switch.
4. Cautions in the Use of Four-legged Touch Switch
As for the welding of the switch, it is necessary to confirm the conditions at the time of production. Because of the different conditions, the compatibility imposed on the terminals, deformation degradation is also possible, so we must pay attention to this point in the process of use. As for the thermal stress effect of the four-legged lightly touch switch, we should make full confirmation preparation before using it; after the first welding, the two welding processes must be restored to normal temperature for the second welding. If heated continuously, the shape of the four-legged lightly touch switch will be affected, and the terminals may also fall off, resulting in a decline in electrical characteristics. The resistance load of the four-legged lightly touching switch is well designed. When using other loads, please pay attention to the confirmation.
