ABSTRACT
In a book of this scope, many sources were consulted to prepare the tables of data presented in this chapter. Most of the data, however, were based primarily upon information drawn from the Doduco Data Book (1). I am extremely grateful to the Technitrol Corporation for permission to freely use the data in this book. Other sources of data were used when that information was not available in the Doduco book. In addition, some of these sources were also used to check the values presented in the Doduco book: examples include, Holm's book (2), and other materials reference books (3-7). Other sources of contact data used to check and to add to these tables were information gathered from brochures and books published by a wide range of contact manufacturers (8-13) as well as information from the technical literature (14,15). It was interesting to note that for some data there seemed to be a considerable variability between some of the values from the different sources, while for others there seemed to be close agreement. Where there was disagreement, I have endeavored to use consensus values as much as possible in these tables. I have also purposely left blank spaces where I could not find values to place there. I would expect readers, as they use this book, to fill in these blanks as the information becomes available.
