Another rating that might be useful to you
         - Pull in voltage 66%V for a continuous coil (60% for 
intermittent) or 7.9V for a 12V continuous coil
         - Drop out voltage  10-20%V or 1.2-2.4V

Given your description so far I suspect you could use an SW200 as a line 
contactor, and maybe replace your solenoids with an SW202 (a motor 
reversing set)
