The laser pointer is broken? How to deal with it?
If your Green laser pointer is really broken, it is probably not worth repairing. Unless it is a particularly expensive laser. In this example, a disassembly and inspection process of a conventional red laser pointer is illustrated. The author spent some time in the process of disassembling the small circuit board in the pen cap, and finally the circuit board was removed after the button was removed. After inspection, the fault that caused the failure of the laser pointer was caused by the failure of the micro switch, and the fault was eliminated after replacing the new switch. Reassembly can be reversed and restored according to the process of disassembly.
