What is a Limit Switch?
An electromechanical device called a limit switch is used to track the location of mechanical parts or determine if an object is present or absent. It is activated by sending a signal to control systems, which then uses the detected location to determine whether to start or stop operations. For exact control and safety to be maintained in industrial settings including manufacturing, material handling, and packaging procedures, this feature is crucial.
Telemecanique limit switches are recognized for their reliability, precision, and adaptability
