Mp3 player power - on/off switch broke

So,I have this mp3 player that is very good for my needs, but its power switch broke off.When I opened the device, I realized that the switch was literally detached from it.This is a photo of the mp3.As the battery was almost detached aswell, I'll weld the it again, that is not a problem...But I'm not sure how I can fix the switch, it can be something improvised, I just need it to work...Any ideas?Thank you so much in advance!!P.S.: Sorry for any english mistakes, it is not my native language.P.S.2.: This is a very old device but a good one, as least for me.

12v 18650 battery with bms but no balance. Can we use 3.7v output from it for powering bluetooth module directly?

I am trying to make Boombox Speaker. The amplifier is 12v and the bluetooth module is 3-5v input. I have a single 12v BMS module, ofcourse with 4.2v, 8.4v, 12.6v dividers. Now suppose I power the amplifier with total output, it works fine. But can I take the output of one single divider i.e. 0-4.2v for the bluetooth module sepeartely and keep using the 12v for the amplifier?
