1. The handle button is malfunctioning. The main reason is that the conductive rubber on the handle is in poor contact with the circuit board. This situation occurs mainly because the part of the circuit board in contact with the conductive rubber is oxidized by air. To remove these oxides, related reports say that chemical cleaning agents are used to remove them, but this method is too complicated. For us, if we encounter this kind of failure, we need to carefully disassemble the game controller, and then use a rubber to wipe the contact point on the circuit board with the conductive rubber carefully. Generally, it can be smoothly removed. Oxide erase. This method is suitable for any game controller, including PS modified controllers that encounter such problems can also be solved by this method. Here, I would like to remind everyone that some PC brand game controllers generally have their warranty period. If it is within the warranty period, you should go to the manufacturer to replace it if you encounter such a problem.

2. Another problem that the handle buttons do not work well is the conductive rubber. Generally speaking, if a handle is used for a long time, the conductive rubber is prone to aging and abrasion. When encountering this kind of phenomenon, we can only replace it by replacing it with a handle that has been used before, or if it is broken (of course, it cannot be damaged by conductive rubber) that cannot be repaired, and replaced with a good conductive rubber. If the model is the same, then the size of the conductive rubber is also the same. If you can't find a suitable one, you can use the conductive rubber cut from a discarded calculator to replace it. Then, my friends, we must come up with various ways to fix it!
