The flow switch MPS is a safety device used in heating systems to detect the flow of water or other fluids. It ensures that the boiler or pump only operates when there is adequate flow, preventing damage from dry running or overheating. When flow is detected, the switch closes a circuit, allowing the system to function. A faulty flow switch can cause system shutdown or erratic operation, so timely replacement is important for reliable performance.
