Some common faults of the light touch switch let us introduce to you, so that you can touch the switch when there are some small faults can be easily handled.
Light touch switch is one of the most common switching elements in our daily life, so there are many details about the use of the switch. If it is not used properly, it will lead to failure. So, do you know the causes of common troubles in tactile switches? Presumably you also know little about these aspects of the switch, the following will explain to you about the light touch switch common fault analysis.
Common troubles of light touch switch
Common faults 1
It is believed that when you touch the switch, you will usually encounter the situation that the key press is not responsive. There are two kinds of problems with this kind of failure. First of all, it is possible that the button switch is too strong, resulting in the damage of the inductive spring inside the switch, causing the button switch to be unresponsive in use. Phenomenon. Secondly, it is possible that the switch in a humid environment, the internal shrapnel is also very easy to be damp will be oxidized, so it is also a switch according to different conduction or non-reaction problems. So we use the switch process, one is to pay attention to the operation of the key switch, the other is to pay attention to do a good job of the switch moisture and other measures.
Common faults two
Generally do not use buttons in the case of wet hands, it is very easy to cause some electric shock accidents. Secondly, if the water vapor intrudes into the inside of the switch, it is easy to make the components inside the switch damp and rust, which will affect the performance of the switch.
Common faults three
When the switch is finished with the welding operation, it should pay attention to the solidification of the terminals of the switch. Do not touch the contact points of the switch, so as to avoid the welding instability caused by the disconnection of the switch. Therefore, it is generally necessary to wait until the solder joints of the switch are completely cooled before the welding condition of the switch can be checked.
Common faults four
Switch in the use of the process is also easy to appear some button bump or press the button can not move the phenomenon, which is generally caused by two cases of failure. First of all, it is possible that in the daily use of the switch, accidentally let some small clutter fall into the switch phenomenon, then it will lead to the switch shrapnel is stuck by some clutter, resulting in the switch button bump not to press. So just remove the debris inside the switch. And compared with the other hand is due to the operation of the button switch too much force caused by the damage of the internal shrapnel, then generally as long as the replacement of this shrapnel component can be, without the whole switch replacement.
Common faults five
In the welding process of light touch switch, it should be noted that the flux added should not be too much, otherwise it is easy to cause the lead pin of switch to be welded through and can not be used. And also for the switch after welding, remember to remove the residual solder in the switch terminal terminal junction, otherwise it is easy to affect the performance of the switch use.
