WebbA limit switch is a type of switch used mainly used to detect the pre-defined displacement or movement of any object. As the name implied, the limit switch is used to define the endpoint or limit over which an object could travel before being stopped. The limit switch engaged to control the travel at this point. Webb7 maj 2024 · 1. Below shows two simple ladder logic examples written for a PLC: As far as I understand, the - - and - / - above are the symbols we write for the PLC not the actual input switches. But we also need to wire actual switches to inputs as field inputs. Is there any convention or good practice to wire NO switch in case (a) and NC switch for case ...
