Hello Tibono,

There are indeed reed switches, but fortunately they are on the top of the PCB. It is not necessary to disassemble the PCB to replace them, as you can cut the pins and solder new ones.

Also attached is a photo of the wheel with the magnets. I once found one of these magnets detached.

Best,
Gerardo
