As andy says add debounce and get screened cables , this is typical of noise pickup on low voltage wireing ,and can also be caused by the wire gauge to be smaller than is needed , and therfore your getting voltage and current losses .

while the machine is powered on and sitting idle and axis is running but the machine is off according to axis i do randomly see the override limits button become active for a split second but it is not on long enough to do anything with.
Considering that homing is slow, and a small delay (of a few mS) in detecting the switch is not super-critical, and that false-triggering of the limit switches can ruin parts and/or be annoying, it is probably not a bad idea to add debounce to your limit switches (Mine have it)
