دانلود کتاب The Boobytrap Recognition Manual - Volume 3 - The F1/F1A1 Combination Switch and its Variants

These publications are a result of my frustration trying to find those little tidbits of information that are spread throughout many books manuals and papers. It is my attempt at putting it all in one place and making it easier to find. I hope you will also find it useful.
The publications will only detail officially manufactured mechanisms, I will not attempt to describe any improvised devices or methods.
It should be noted that the photos are certainly not all mine, I have been collecting photos from other collectors, museums and off the net for years and as a result of poor record keeping in many cases have no idea where I found them. If you find one of your photos in here and your name is not in the credits, please accept my apologies for using it without permission.
This book is not simply my effort, many people have contributed to its completion, have read it over, offered corrections and pointed out blatant errors. You know who you are and my thanks for your help. If you happen to find one of those errors, please let me know so I can correct it.
Enough said, on to the interesting bits…
