I've never seen inside the remote but my guess is that they incorporate a reed switch to reduce contact bounce. I made my own remote and used switches with a very positive click so as to avoid partial contact or bounce. You should have little trouble building a long wired remote, following is a part of a post of mine from June 04 relating to building a *ist D remote: I found a very inexpensive source for suitable pre-moulded cables in a universal hands free mobile phone kit which uses the 2.5mm stereo plug (AU$1). I cut the mic and earpiece off, found some suitable momentary switches and a small piece of Vero board. I shaped the board and fitted the switches, I then soldered it and covered the assembly in epoxy cement to smooth the surfaces and to strengthen and protect it. http://home.swiftdsl.com.au/~distudio/temp/_igp4669.jpg It works well, the red button is the shutter and the black AF. It's perfect for inclusion in my pack as it's just over 16mm x 29mm x 11mm excluding the cable. It has no shutter lock however I really don't need one in this case (but it would be really easy to incorporate one). Total cost about AU$5.00 excluding labour :-) I intend to simply modify a Cable Switch F by fitting one on these cheap cables as my studio bound cable release.
