| Limit switches are used to detect when some mechanism has hit some form of limit. For instance, a limit switch would be used to detect when an elevator is at its lower limit or when an arm is at its maximum angle. | Limit switches are used to detect when some mechanism has hit some form of limit.

| To [[Designing for Control|design for controllability]], every mechanism that has a limit should have a limit switch on it. Ideally, there should be at least one limit switch and a [[Quadrature Encoder]]. | To [[Designing for Control|design for controllability]], every mechanism that has a limit should have a limit switch on it.
