1. Prepare the tools for the switch first. You can use a small handkerchief to repair the watch; you can also use a thin wire to smooth the front end and use it as much as possible, or use a thin blade or bamboo toothpick.
2. One side of the micro switch is next to other components, and it is not easy to remove it. Usually there is no component blocking on one side, you must first squat from this side.
3. Take a closer look before disassembling. There are two clips on the micro switch, and it is stuck. You must use the toothpick to hold the clip of the micro switch, and then gently pick up the cover of the micro switch from the bottom of the micro switch. If the force is too strong, the side of the cover will fall off.
4. Then use a straightened paper clip to insert the clip from the side of the disengagement from the micro switch to the opposite side, and the cover can be taken off!
When removing the top cover of the switch, do not use excessive force. One, it is easy to make the top cover suddenly off the base, which will make the small red button inside pop up. Once the bomb is flying, there are not many opportunities to get back. Because it is too small and difficult to process, the switch is completely scrapped; second, it is easy to split the buckle between the upper cover and the base, causing permanent damage.
