When the switch is used, it often encounters some problems, which problems are usually more? Let's give you a detailed introduction.
Toggle switch is a very common switching element in our life, so there are many details about switching operation. If the operation is improper, it will lead to problems. So do you know why the common problems of the switch are analyzed? I guess you also know little about these aspects of the switch. Next, I will explain to you the common problems of the switch.
Common problems encountered in switching switches:
Problem 1: Switches are also prone to bump or immovable keys in the process of operation, which is generally caused by two situations. First of all, it is possible that in the daily operation of the switch, accidentally dropping some small debris into the switch will cause the shrapnel of the switch to be jammed by some debris, which will result in the condition that the button of the switch will not move. So just clean up the debris inside the switch. On the other hand, the internal shrapnel is damaged due to the excessive force of operating the key switch. Generally, it is only necessary to replace the shrapnel element without replacing the whole switch.
Question 2: It is easy to cause some electric shock accidents if you don't press the button to operate the switch when your hands are wet. Secondly, if water vapor intrudes into the inside of the switch, it is easy to make the components inside the switch become wet and rusty, which will affect the performance of the switch.
Question 3: In the welding process of the switch, we should pay attention to the fact that it can not add too much flux. Otherwise, it is easy to cause the pin of the switch to be welded through, leading to the failure of operation. Also, after the switch is welded, it is important to remember to remove the solder residue at the terminals of the switch. Otherwise, it will easily affect the performance of the switch operation.
Question 4: It is believed that when you operate the switch, you will usually encounter the condition that the key press is unresponsive. Generally, there are two situations for this problem. First, it is possible that the force of the key switch is too strong, which will lead to the damage of the inductive shrapnel inside the switch, resulting in the phenomenon of no response in the operation of the key switch. Secondly, it is possible that the internal shrapnel of the switch is easily oxidized by dampness in the humid environment, so the switch can be turned on differently or without reaction. Therefore, in the process of switching, we should first pay attention to the operation of key switches, and secondly, pay attention to the moistureproof measures of switches.
Question 5: After the completion of the welding operation, the switch should pay attention to the solidification of the connection points at each end of the switch. Do not touch the connection points of the switch, so as not to easily lead to the disconnection of the switch and lead to unstable welding. Therefore, it is generally necessary to wait for the solder joints of the switch to be completely cooled before the welding condition of the switch can be checked.
The above is about the analysis of five common problems of the switch. The analysis of the common problems of the switch is explained in detail. The key points of attention about the switch can not be ignored in operation.
