How to Connect Pushbutton Switch to PLC

We will connect a lighted pushbutton switch to a programmable logic controller (PLC). Using our Click PLUS PLC, we will be assembling, wiring, programming, and testing our pushbutton switch system. The Fuji Electric pushbutton, normally open (NC) contact, will be wired to the first PLC (X1) input. The LED light will connect to the Click PLC (Y1) first output.
How to Connect Pushbutton Switch to Programmable ControllerFerrules will be discussed and demonstrated as a method of wiring any stranded wire. The use of ferrules applies to any automation devices with screw terminals. A ladder logic program will be developed to start and stop this lighted pushbutton light using just a single input. The output LED will turn on if the button is pressed for three seconds. Pressing the button again will turn the light off. This is the safest way of using one input to start and stop output. Let’s get started.
