I've never been involved with a robot with a limit switch - usually potentiometers dictate anything that would otherwise be limit switched.

Usually, a potentiometer is a good enough limit for most mechanisms, though I prefer to add a limit switch as well, just in case the potentiometer should shift or misread.

When we implement limit switches, we like to set a "hard" (Usually has a little play to cushion the impact) mechanical stop in the same location as well. This saves the body of the switch from seeing any actual force from the mechanism. I believe the most limit switches we've used on a robot was either 3 or 4, though this year it sounds like we may have more than that.
