Touch switch is basically one of the most common switching elements in our daily life, so there are many details about the use of the switch. If used improperly, it will lead to failure problems. So have you ever known the cause of common faults of light touch switch? I guess you also know little about these aspects of switch. Next, I'll explain to you the analysis of common faults of touch switch.
Common Faults of Touch Switch
Common failures
It is believed that when you touch the switch lightly, you will usually encounter the condition that the key press is unresponsive. Generally, there are two kinds of problems for this kind of failure. 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 and cause the key switch to be unresponsive in use. Phenomenon.  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 using the switch, we should first pay attention to the operation of the key switch, and second, pay attention to the moisture protection measures of the switch.
Common failures II
Usually in the case of wet hands do not press the button to use the switch, it is easy to cause some electric shock accidents. Secondly, if water and gas intrude 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.
Common failures 3
After the completion of the welding connection 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.
Common failures 4
In the process of using the switch, it is also easy to appear some key bumps or keys are not moving, which is generally caused by two kinds of failure reasons. First of all, it is possible that in the daily use of the switch, accidentally some small debris fall into the switch, which will lead to the shrapnel of the switch being stuck by some debris, resulting 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.
Common failures 5
In the welding process of light touch switch, we should pay attention to the fact that the flux should not be too much. Otherwise, it is easy to cause the pin of switch to be welded through, which leads to unusable situation. Also, after the switch is welded, it is important to remember to remove the solder residue in the terminal terminals of the switch, otherwise it will easily affect the performance of the switch.
The above is about the analysis of the common faults of the light touch switch part. The analysis of the common faults of the light touch switch is explained in detail. Therefore, in general, the attention to these details of the switch can not be ignored in the use. If you need to encounter any faults or purchase lightly touched switches when using lightly touched switches, please feel free to consult us.
