Multiple Choice

The stop switch is activated by which of the following?

Explanation:
Air pressure powers the stop switch. In air-brake systems, this safety device monitors the level of compressed air in the system, and when pressure drops below a safe threshold, the stop switch activates to stop the engine or prevent further operation. This protects you from driving with brakes that may not function properly. Brake fluid pressure is part of hydraulic brake systems, electrical voltage is not the trigger for this switch, and hydraulic pressure isn’t the control medium used in air brakes.
