This might be worth a try if you are having disconnect issues that seem difficult to fix. It requires hacking into the limit switch harness to do, but should provide great isolation on the limit switch cabling, which is not shielded, and will likely pick up a lot of noise off the router.

This works quite nicely- cleaned up some noise I was getting with very long (6ft+) cables.
