little battery cover switch.

Hello,

my 650D could no longer turn on.

I found on the Internet a note that it could be the battery cover switch (little secure switch when you open the battery-cover). As I pressed the little switch with the screwdriver the eos turned on. :D

In the Internet I was supposed to bend the small switch with the screw in the middle. At the attempt the switch broked : /

Now my questions:

Can this switch or the board be replaced?

If so, what is the description of this board-part?

Can you simply bridge it? (I can solder)

I would like to unscrew the camera when I know more about it.

Thank you.
