Limit Switches for PLCs

An electrical switch is a device that can close and open a circuit. Limit switches are, in general, electromechanical devices and are operated by the motion of some external object such as a machine part. In an HVAC system, a limit switch is often used to monitoring the state of a damper or valve.
