In heavy-duty commercial pressure washers, relying on basic pressure switches can lead to erratic pump pulsing and severe mechanical stress when using long hoses or chemical injectors. This premium \u003cstrong\u003eflow control switch\u003c\/strong\u003e operates purely on water movement rather than built-up pressure. When you pull the trigger gun, the water flow physically activates the switch, instantly turning the massive electrical motor on. When you release the trigger, the flow stops, and the switch instantly shuts the motor down, preventing the pump from dead-heading and overheating.\u003c\/p\u003e\n\n\u003cp\u003eEngineered for extreme industrial environments, the newly developed ST-7 entirely replaces fragile, traditional REED-contacts with a formidable, heavy-duty industrial micro switch. This massive upgrade delivers a significantly higher electrical output capacity and a vastly extended operational lifespan. Crucially, the internal hydraulic water chamber and the electrical components are completely separated, guaranteeing maximum operator safety against water ingress and short circuits. Featuring a highly sensitive, low switch-on point of just 1.5 L\/min and creating a minimal pressure drop (only 1.5 bar at 30 L\/min), this essential \u003cstrong\u003epressure washer part\u003c\/strong\u003e is the ultimate upgrade for custom extraction rigs and heavy-duty wash bays.\u003c\/p\u003e\n\n\u003ch3\u003eWho Is The ST-7 Flow Switch Ideal For?\u003c\/h3\u003e\n\u003cp\u003eThe ST-7 delivers industrial micro-switch reliability and completely separated hydraulics.
