Hi! So where can I get the spring part?
Hey! You can make a fix by bending a bit of stripped copper wire. I uploaded some Images of my fix, it worked reliably you just had to be careful when replacing batteries.
However i have found my original spring. But whiles searing for one to buy i stumble on many on Aliexpress that you could bend to the correct shape, Maybe this FW-DCTHZ9X20 (Seller) would work as the end part of the original spring is as well 9 mm.
