You might get lucky and never have a case of over travel. I and many others werent.

Or when setting up home and limits, you turn them off for a moment and jog the wrong way. Your switch and housing are destroyed.

Though I like the attention to detail you 2 are performing, in this case the switch either needs to be activated by a ramp that can pass by while simultaneously pressing the switch. Or use an opto switch with a gate and blade arrangement. Or even a proximity switch. Those will allow for over travel.
