Canon Wired Remote

Step 5 Wiring It Together

Fire up your soldering iron, and get ready to make all the connections. The pictures aren't very clear, so I'll explain how to wire everthing.

Cut off one of the outermost leads of the two-way switch and insulate with a piece of head-shrink tubing. This will ensure that when the switch is slid in this direction, the remote will be "off" and the buttons will not function, preventing accidental triggering of the shutter. Wire one lead from each pushbutton switch to the other outermost lead of the two-way switch (opposite the one you just cut off). Solder one of each of the 3 twisted wires to each of the remaining contacts - one to each pushbutton and one to the center lead on two-way switch. Make sure to insulate everything!

I added a couple schematics-choose whichever you like better.
First Schematic: Switch(that thing in the middle of the drawing) up: buttons focus & take picture. Switch down: remote is off; button's don't have any effect.

Second Schematic: Switch(that thing in the middle of the drawing) up: butons focus & take picture. Switch down: Take picture until switch is slid back up (ideal for bulb exposures!!!).

I wired mine the first way, but I wish I had done the second. =/ Don't make the mistake I did!
