I have broken three contactors. The seem to shutter on and off while engaging. Then when i check them later the metal conductor on the contactor is broken off with the spring. Any ideas? What are some possibilities? Any info is very much appreciated. Thanks

Low voltage or possibly some type of electrical interference. Putting a snubber across the coil may help.

Whats A snubber?

R/C Network (combination of a resistor and a capacitor).

Thank you can you point me in the direction of where to find one and how/where to install it. Thanks

Radio Shack is where I get mine, it does not come up much these days. There are several factors that will dictate what capacitor and resistor combination you need. I would search the net and see if any of spa sites sell them.
