Just to clarify - a "limit switch" is not a special kind of switch, it's a switch that we use to limit motion. One doesn't buy a "limit switch", you choose among microswitches, optical switches, magnetic [reed] switches, ..., for a switch that mechanically fits and triggers at that point in the motion of whatever you need to stop on your robot. They are not wired directly to a motor, but to a Digital Input on the roboRIO/cRIO/Arduino, etc. The program running on that computer will sense that the switch has opened/closed and will control that motor's Jaguar/Victor/Talon speed controller appropriately.
