It senses vacuum level and opens or closes its contact at a preset threshold so the pump runs only when needed, reducing motor wear and improving system reliability. The unit ships with a factory-set adjustment and a protective coating for corrosion resistance.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this switch stop the pump from running constantly?\u003c\/h3\u003e\n\u003cp\u003eThe Dracarys switch monitors vacuum and toggles its contact when the factory-set vacuum point is reached. It typically operates through a relay or direct wiring to the pump motor, cutting power when the vacuum is sufficient and reapplying power when vacuum falls below the threshold. That prevents continuous motor operation and reduces heat and component wear.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFactory-preset activation and deactivation points for consistent performance.\u003c\/li\u003e\n  \u003cli\u003eGlue-secured adjustment screw to prevent transit loosening.\u003c\/li\u003e\n  \u003cli\u003eWorks with a pilot relay or direct pump wiring depending on installation.\u003c\/li\u003e\n  \u003cli\u003ePower-coated finish resists corrosion in engine-bay environments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs the vacuum setpoint adjustable and what should I expect at installation?\u003c\/h3\u003e\n\u003cp\u003eThe switch is supplied with a preset vacuum range and the adjustment screw is glued to prevent accidental changes during shipping. That means no field tuning is required and the unit will operate within its designed threshold out of the box.
