Limit Switches, Their working principle, Application, and Types
Limit switch are switches operated by a machine part's motion of an object's presence. Limit switches use control machinery as a security interlock, a part of an impact system, or to count objects passing to some extent. Limit switches are electromechanical equipment containing an actuator mechanically connected to a group of contacts; when an object comes in-tuned with the actuator, the machine operates the contacts to form or cut an electrical connection. Limit switches are applied in multiple applications and environments due to their ruggedness, simple fitting, and operation reliability. Limit switches can ascertain the proximity or absence, passing, positioning, and travel of an object. Limit switches were first wont to define the limit of travel of an object, hence the name "Limit Switch." Working Principle Limit switches with a roller-lever operator; are connected to a gate on a canal lock and indicate a gate's position to an impact system. Limit switc
