When the stop button is pressed, the control relay will ___.

• A. deenergize and reenergize when the stop button is released
• B. deenergize and stay deenergized until the start button is pressed again
• C. not change states
• D. activate the coil

Answer: (B)

When the stop button is pressed in a control circuit, the function of the control relay is typically to interrupt the power to the coil that energizes it. This action causes the relay to deenergize. Once the stop button has been pressed, the relay remains in a deenergized state, which means that it will not return to its energized position until a separate action, such as pressing the start button, is taken to restart the circuit. This is a fundamental concept in control systems, particularly in safety or operational circuits, where the intentional act of stopping a process should ensure that it does not restart until explicitly commanded. Thus, the relay will remain deenergized and inactive until the start button is pressed again, ensuring controlled operation and safety in the system.
