Soldering 'Card Cover Open' Switch Closed

I had the same problem after a little plastic trigger thing fell out of the hole above where it says push to eject. After poking around for a while I took the camera apart (remove 7 screws) which made it much easier to see, with a magnifying glass and lamp, what the problem was. A damaged wire that needed to be connected to something. Only the very end of the wire was visible, inside a small white plastic box thing. The plastic box thing eventually fell apart with my attempts to put in bits of wire of varying shapes. When it came loose I was left with a short stiff bit of wire. I took a strand of copper wire (from an old piece of electrical wire), twisted it so I had a small loop at one end, looped it over the end of the stiff bit of wire, and then curved the rest of the wire (about 3 - 4 cm long) so it was resting on a silver piece of metal just below where the white plastic box had been. Put the cover back on and the camera worked. Needless to say, it won't let me know if I've left the cover off, but then it won't work unless the cover is on, so it doesn't seem to matter. Saved about $100.

Yes, same as above only I didn't have to touch the metel piece. Just took an electric wire (thin) and wrapped it around each little connector after taking the white piece off. Came right on!
