hello i am looking for this power button if you can tell me the model and where i can buy it. thank you
Probably this:
https://www.amazon.com/Davitu-Self-locking-Switches-PS-22F03-Latching/dp/B07L938ZPD
No idea if it fits 100% correctly, if it's rated for the same power, etc but they're so cheap it's worth a try... Do it at your own risk.
Let us know how it goes and good luck.
(PS edited your huge pics, hope you don't mind)
