Hasbro Force Action Obi-Wan Kenobi broken PLEASE HELP!!!!

HI! Im from Argentina and I bought a Hasbro Force Action Obi-Wan Kenobi lightsaber in 2007. I tried to replace the batteries compartment, but ended up breaking the hilt to open in the middle the lightsaber. And I lost the switch button. I dont think Hasbro would replace or refund me the lightsaber because of the place where I live, and because its been too long since I bought the lightsaber. My plan is to weld again the small wires, adjust the spring, try to manufacture a new switch by molding some old plastics or with cold porcelain, screw again the saber, and glue the ring that goes under the hilt . It would help me a lot a schematic or photo of the interior of the saber, so I can see where each thing fits and how to specifically manufacture the switch. From already thank you very much...
May the force be with you

Perhaps this would be of help:

Force Action? You mean the plastic sabers? You're probably not gonna be able to fix that.
