Shutter release help - Canon Digital Rebel

I have a Canon Digital Rebel XTI 10MP SLR camera. I am vacationing in
a remote part of the Adirondacks and have no access to any camera
shops that have accessories for my camera. I am interested in doing
some time exposures with my camera. I have found online what appears
to be the remote cable release accessory, Canon part RS-60E3. I have
noticed this accessory appears to be simply just a push button
presumably to close a switch. I cannot understand then why they have
used a 2.5 mm "stereo" type plug that has three terminals rather than
a mono type having two connections. I would have assumed that a push
button switch is just closing a circuit to activate this time delay
function and therefore if that was the case it would appear that we
would only have to use two terminals of the plug. Perhaps that is
what they did but I wouldn't know not having a sample to autopsy. I
have a 2.5 mm plug with a stereo wire on it (3 wires, ground, left and
right). Does anyone think that it would harm anything to short
different combinations of these wires together to try to activate the
time delay function? I only have a few more days out here and the
scenery is breathtaking and I would hate to miss some moon light
shots. However, I really don't want to take a chance and damage my
camera either. If anyone has any information on the RS-60ES,
specifically how it's wired internally (so that I might duplicate it),
I would sincerely appreciate hearing from you. I also own a Nikon
8008s that I was able to build my own time release switch for. (The
Nikon has two pins that when shorted triggers the shutter) and my
simple home made accessory worked just fine. I would really
appreciate it if you could let me know. Thanks very much for any
assistance, Jesse.

Halfway down, all the way down. Just like the shutter.
(Oh, and you can freeze the button in full down position,
sliding a slider.)

Doubt it.

Google for homemade remote canon digital rebel and you shall
find many answers.

The first post didn't seen to go through, so I hope I am not repeating
repeating myself.

Try a universal TV remote. They are available everywhere.

Hello Jesse.

I've just put a test meter across that jack plug and it does use all three
connections.

I suspect that the wiring of the plug may be:

1. Body is common connection,
2. Ring switches on the camera's metering/focussing and
3. Tip fires the shutter.

It's just like the camera's own shutter button - the first pressure on the
RS60-E3's button switches on the metering and focussing systems then a
further pressure actually fires the shutter.
The button on the RS60-E3 can, as another posting said, be slid along to
hold it in the "shutter open" position (assuming that the camera's shutter
is set to Bulb.


Oh - I nearly missed your assumption that the RS60-E3 is for a time-delay.
No, this is not the case. It is simply a remote shutter release.

Hope this helps,

Ian.

Here is the functioning for the Canon Digital Rebel XTi (400D). All you
want to do is connect the ring and tip together permanently, and then short
these two to the sleeve when you want to expose.

If you need a ready source, the 2.5mm 3-way plugs are hidden at Walmart as
various phone and iPod headsets.

Hello Jesse.

We're always happy to help because we, too, learn as we help.

Have fun with photography.

Helps me too. I've been using a home made remote release using two
microswitches built into a pistol grip with trigger that originally had a
mechanical cable release. Built it years ago for use with a film EOS camera,
connections as above. So I was wondering if I could transfer it to a Canon
DLSR - if I bought one...
