Six Problems to Be Noticed in Using Light Touch Switch

What should be paid attention to when using the light touch switch? We summarize six points. Here we give you a detailed introduction.
The use of light touch switch is relatively common, but there are many problems to be paid attention to in the operation of the switch, so do you have a detailed understanding of the basic elements of attention in the use of light touch switch? This slightly improper use of the switch will lead to the failure of the switch. Presumably, as non-technical personnel, we are sure that usually very little to understand this knowledge, then the following will give you a detailed explanation of the patch touch switch using the basic elements of attention.
In the use of patch light touch switch, please be careful not to let foreign bodies intrude, even some minor impurities or foreign bodies, will lead to a decrease in the sensitivity of the key that affects the switch.
Secondly, in the use of conventional light touch switch, we should try to press the key switch in the center of the switch, not slanting or side pressing the switch, in order to avoid the phenomenon that the switch will cause the key to be stuck and pressed immovably and the key to be convex and subsided.
In the welding process, please pay attention to the welding temperature should not be too high. Otherwise, the added rosin atomization will invade the switch and cause bad internal conditions. At the same time, please pay attention to the control time, so as to avoid the possibility of breakdown or damage of the switch.
When lightly touching the switch during over reflow soldering, it will leave some excess tin in the operation, or at this time, do not use industrial alcohol to clean the switch interior, because industrial alcohol will corrode the metal part of the switch, which will make the switch lose its function. For the treatment method, some rust-proof oil can be used to wipe off the excess tin on the internal contacts of the switch. Secondly, it can also play a certain role in preventing rust in the use of the switch.
When installing the light touch switch, please note that the connecting lines should be arranged neatly and reasonably. Do not stack all the connections of the switches together, so as not to cause accidents such as safety and so on in the frequent use of switches, because the internal circuits of switches may not dissipate heat.
Because of the small distance between the contacts of the patch key switch, it is easy to cause short-circuit fault of the switch if there is oil pollution and water and gas intrusion. Therefore, in general, in the daily use of switches, it is necessary to keep the buttons clean, and at the same time, do not use the buttons in the case of wet hands, so as to avoid the safety accident of electric shock.
Because of the time relationship, today's patch light touch switch use basic attention elements and other common sense, review before also roughly to tell you about light touch switch common fault analysis.
