What is a patch key switch? In fact, this is an inductive switch. By touching the button of the switch by hand, the circuit of the switch can be turned on or off. The main principle of this kind of patch button switch is to rely on the force of the metal shrapnel inside the switch. To realize the on-off function of the circuit, if our key switch is used or operated improperly, it is easy to have some use failure problems. In this process, even some very small conditions , it is easy to affect the generation of these major faults, so today Xiaobian will introduce our button patches in detail. What are some common faults that the switch will encounter during use? And what is the solution to these failures?
One of the faults that our patch key switch often encounters is that due to the relatively small size of this product, there will be many deficiencies in the use of the switch For example, when people often press the button of this switch, it is easy to make the internal shrapnel of our switch touch very frequently. After a long time, the shrapnel will be subject to certain wear-resistant fatigue. After reaching a certain number of times, our switch will be damaged, or it will be impossible to use it, so everyone must remember not to press this patch button switch frequently. This is our patch key switch. The first fault that we often encounter is that the second fault of our patch is that the terminal part of our patch will change color or the internal shrapnel will be oxidized. So this kind of failure occurs because of these patch key switches, which have been in a high temperature and high humidity environment for a long time, and this kind of situation is easy to occur. Of course, sometimes direct sunlight can also cause this kind of failure. If so, how can we avoid this failure? You should try to install these patch key switches in a normal temperature environment, so that our switches can be far away from this more extreme environment.
Of course, sometimes the failure of the SMD key switch is not determined by the product itself. Sometimes, when the customer disassembles the product by himself, it is easy to have various problems. Sometimes, when we find ourselves When the response of this switch is not sensitive enough, most people will feel that they can also operate and maintain this switch. In fact, this method is very dangerous. Its maintenance is not very well understood. After all, everyone is not a professional. If you operate it privately, first of all, it will easily cause certain damage to the use environment of our high-end electronic products, because our Electronic products need to be isolated in a dusty environment before they can be operated. After all, it will have a conductive effect in the dust, so we privately repair it, not only can not solve the problem, but also sometimes aggravate the problem. Therefore, when you find that your key switch is faulty, we can directly call the professional maintenance personnel and ask them to help you with the maintenance.
