The battery of mosquito swatter is broken. You only need to master this skill to easily repair it. From the point of view of maintenance practice, most of the failures of the battery box are battery leakage, which causes corrosion, oxidation and poor contact of the positive copper plate or negative spring, resulting in the failure of the mosquito swatter to work, and the rust can be completely scraped off with a knife. If the mosquito swatter is not used for a long time, it is suitable to unload the battery, which is a good way to prevent the electrode from rusting and oxidizing Zui.

　　The battery consumes electricity for a long time. If the voltage of each battery is lower than 1V (the brightness of the indicator LED is dark), the high voltage will be insufficient and the mosquito killing effect will be poor. Replace two new batteries.

　　If there is something wrong with the power switch of the mosquito swatter, you can repair it as follows:

　　The power switch of mosquito swatter is usually 6x6mm touch type micro key switch, which works under the condition of 120-200ma. Due to frequent operation to turn on and off the power supply, it is easy to damage. There are two types of damage:

　　What should I do if the battery of mosquito swatter is broken? It's too easy to maintain.

　　(1) The contact point is in poor oxidation contact, the indicator light is not on, and the mosquito swatter does not work.

　　(2) The reed is tired, the contact is stuck, and the indicator light is always on. Once the battery is installed, the mosquito swatter will work. The micro switch is small in size and troublesome in maintenance. It is usually replaced with a new one.
