A limit switch is a switch operated by the motion of a machine part or the presence of an object. They are used for controlling machinery as part of a control system, as safety interlocks, or to count objects passing a point. A limit switch is an electromechanical device that consists of an actuator mechanically linked to a set of contacts. When an object comes into contact with the actuator, the device operates the contacts to make or break an electrical connection.
