Reverse Ramps???????

Your LIMIT SWITCH should not also be serving as a HARD STOP. Overshooting the limit should not do anything to the switch. If your switch will be damaged by a movement, then your design is incorrect - move the switch out of harm's way.

And that's ANY movement. You'd think that mounting one to stop our arm would be fine. Nope. We mounted it too close to the backside's swing and then went to check the position of the one for the other side. Whirr (motors backdriving) tip (we tilted the bot forwards) click (throw arm hitting the floor). Followed by: "Uh...I think we need a new limit switch..." The switch still worked, but its arm was twisted and out.
