PowerShot A550 shutter button

Hello, does anybody knows where shutter button contacts are located on the A550? I mean, is there any pad or pin on a connector in which I can "intercept" the shutter contact?
Is there a schematics available somewhere?
thanks
Dr.Marten

Please don't cross post the same question in multiple places.  This is a small forum with fairly low traffic and the few people who might be able to help read every post.

As far as your camera goes, I don't think anybody active here has an A550.  It sounds like you could answer the question yourself simply by opening up the camera?  Or am I not understanding the question.

Also, why do you want to know where the contacts are?  If you are planning to attach some sort of remote switch, there are less destructive ways to do that with CHDK :  USB Remote

HTH !

Hello Waterwingz,

yeah I posted twice by error, sorry for that.

anyway, I'm looking for a service manual, in particular I need electronics schematics of the main PCB.
(I like to transform things...in other things)...
thanks for your help

AFAIK Canon do not provide PCB schematics in service manuals. They do not repair PCBs.
