Place the pushbutton on the breadboard. Most buttons will straddle the center trench on the breadboard. Connect a jumper wire from the 5-volt pin to one side of the pushbutton. Connect a jumper wire from pin 2 to the other side of the pushbutton.
A push button switch is a small, sealed mechanism that completes an electric circuit when you press on it. When it’s on, a small metal spring inside makes contact with two wires, allowing electricity to flow. When it’s off, the spring retracts, contact is interrupted, and current won’t flow.
What are the 3 wires on a starter?
Typically, a starter-mounted solenoid has three terminals with three connections: The “B” or “battery” terminal: The terminal that connects the solenoid directly to the positive battery cable. The “S” or “start” terminal: The terminal that receives power from the ignition switch.

The selector switch usually locks into a position. We will be wiring two illuminated pushbutton switches into our Click PLC. A selector switch will also be wired in. Let’s get started. Additional discrete component connections to PLC include the following:
If the pushbutton or switch activates it, the contacts will close. Red is a normally closed contact block. If the pushbutton or switch activates it, the contacts will open. We will use our Click PLC program from our Wiring Stack Light to Click PLC post.
How is the button on the Arduino connected?
One button’s pin is connected to GND, the other is connected to an Arduino’s pin with a pull-up resistor If the button is pressed, Arduino’s pin state is LOW. If otherwise, Arduino’s pin state is HIGH We can use either an internal or external resistor.
