First, responding to your question � Several things on copper dissolution in solder are: * A 50um copper wire will dissolve in 60Sn / 40Pb solder at: - 200�C solder in 55 seconds; - 250�C solder in 20 seconds; - 300�C solder in 5 seconds; - 350�C so

Can I replace this broken micro switch and solder the new one like this ?

If I was you, I would use solid copper wire and modify the new switch to have contacts same location and size as the old one. Then solder the same spot a s a full replacement.
