Limit switches are widely used in various industrial applications, specially for automatic and semi-automatic control purposes. Limit switches are designed to control the movement of a mechanical part in order to stop a moving element driven by a motor when a predetermined deflection or end position has been reached. Limit switches can detect a limit of movement of an article and passage of an article by displacement of an actuating part such as a pivotally supported arm or a linear plunger. A conventional limit switch generally has an actuator of a lever type rotatably supported by a hinge. Normally, a limit switch assembly is provided at a stationary position along the path of reciprocation of the part for actuation by limit stops or cams projecting from the part. One type of limit switches serve the function of connecting and disconnecting circuits in a fashion that is related to a given set of inputs. The inputs typically are mechanically derived positions that are linked to the device that is being protected by the limit switch.
