How to deal with some problems when the side-press light switch is in use? What are the specific details? Let's give you a detailed introduction.
One of the most common parts of electrical appliances in life is the switch, which is used to control the disconnection and connection of power supply. However, with the development of science and technology, there are also various types of switches. Side press light touch switch is a new type of switch, which is also called key switch. It first appeared in Japan. When it was used, it mainly controlled the connection and disconnection with power supply by satisfying the operating conditions. Next, I will summarize some problems and solutions which are easy to appear.
The side press light touch switch is mainly composed of inserts, shrapnel, buttons and cover plate. Among them, it has the advantages of small contact resistance, accurate operation error and diversified specifications, and is widely used in family life and many work places. But there are also some corresponding problems, such as the hand feeling problem, the touch of the switch and the key force are controlled by the shrapnel. The shrapnel is divided into phosphorus-copper shrapnel and stainless steel shrapnel. Based on the high performance-price ratio of phosphorus-copper shrapnel, the manufacturer will choose to use it in order to save cost. However, phosphorus-copper shrapnel will deform and shrink seriously after high temperature, which leads to the problem of bad hand feeling. Stainless steel shrapnel can be chosen as far as possible.
Adhesion problem. If the light touch switch is ultra-thin, it needs thin film to cooperate. Many thin films have poor temperature resistance and will fall off after the furnace temperature has passed. However, if imported rubber is used, it is not easy to fall off. Some domestic rubber will be more prone to fall off, and attention should be paid to it when choosing and purchasing. The cover of the switch falls off. The cover of the switch is on the back cover. It is mainly fixed by four riveting points. If the riveting points are loose, the cover will fall off easily. So in order to prevent such problems, we should pay attention to two problems. One is that the base is made of heat-resistant materials, and the riveting points should be fixed well. These two measures can solve this problem.
Light press does not lead the problem. Switches are mostly exposed to the air, so in wet weather, the shrapnel of the switch is easy to be oxidized, and then the contact performance will be greatly weakened. If we open the switch, we will find that there is a black spot on the shrapnel, that is, the effect of oxidation, so we usually do not use, electronic products should be placed in a dry place to prevent oxidation.
Above are some problems that are easy to occur when the side-press light switch is used in life, and there are corresponding solutions. In this way, when you buy and use it in your life, you can also have a certain reference and help. Life tips are also derived from it.
