can some one help me with my homemade Bite Switch?

Recommended Posts

Hello every one!
Im trying to build a bite switch for my canon eos 350d and I think I have all the parts but I have some difficulty connecting the different cables with each other.
If you look at the picture I attached you can see that the first cable have 3 wires and the second cable have 2 wires.
Should I skip the wire with the question mark or do I need all 3 of the wires to get it to work?

Blue skies !

Looks like the wire in question is bare wire? if so there's a good possibility its either a sheild of some kind or a ground. Easy thing to do would be to just strip and connect the 2 insulated wires respectively, try it out and if it works then go ahead and solder them into place. At least that's the approach I would take.

Read these posts where I've written some pretty long explanations:

In short, the 3 wires from your camera are shutter, focus, and ground. Touch shutter and ground together and it opens the shutter. Touch focus and ground together and it focuses. Touch all 3 together and it focuses and fires.

You want to short focus and shutter, and keep ground separate. This way when you press your switch you'll be activating both the focus and the shutter.

Some people like to short their focus to ground so that it's "always focusing"... not only do I think this is unnecessary, when I tried it actually wouldn't fire even when I connected shutter to the focus/ground pair... it would just keep focusing forever and never fire the shutter.

Try it all out before actually soldering/heatshrinking. You can figure out everything I just explained with 10 minutes of trial and error. Good luck.

A monoplug switch (as opposed to a stereo) switch will constantly focus. At least that's the way conceptus sets it up. I find that focusing is better overall (especially exit shots) with the monoplug. The downside is that you cannot access your camera's menu with the monoplug plugged in, as you can with a stereo plug.
