He wired an using two pressure switches. The cylinder remained stubborn, motionless. He pressed the first button—nothing. He pressed the second—nothing. Only when he pressed both did the circuit complete its logic. It was a mechanical pact: cooperation or stillness. Electropneumatics, Basic level (Workbook)
