A magnetic control valve is to block an outlet end of a water inflow passage and an inlet end of a water outflow passage of a connection pipe by using a rubber ring. A valve of the rubber ring is opened or closed by a magnetic control switch. The magnetic control switch mainly takes a valve rod carrying permanent magnetic force that completely controls direction of electromagnetic pole as a power source for moving. When a valve plug at an end of the valve rod seals the valve, a metal plate capable of being sucked by magnetic force is combined with the rubber ring to allow both to generate magnetic sucking effect, thereby firmly closing.
