Hi,

I have a camera hooked up to a 9v battery and want to be able to use a
'timer switch' to turn it on at a specific time ( like the ones you
plug into a wall socket and then plug in your light socket and get it
to switch your light on automatically at a certain time when your away
)

Is there such a thing that can do this with a battery as the power
source?

Any help on this would be gratefully appreciated

It's possible, but you'll need to specify how you want to start the
timer, how long the delay will be until it turns on the camera, how
long you want the camera to be turned on (as well as what you mean by
"turned on". That is, is it a simple shutter release, is it a
camcorder of some sort that you want to run for a while, or is it
something entirely different) and anything else you can think of.

Probably the best thing for you to do would be to describe your
application, and that way we can fill in some of the blanks.
